Apologetics

1. "There is no evidence God exists."

Objection

God's existence cannot be demonstrated. There is no empirical proof, and belief in God is a matter of blind faith, not reason.

Reply

The Catholic Church teaches that the existence of God can be known with certainty by the natural light of human reason from the things that have been made. This is not blind faith but reasoned inference.

Scripture itself attests to this: "For the invisible things of him, from the creation of the world, are clearly seen, being understood by the things that are made; his eternal power also, and divinity: so that they are inexcusable." — Romans 1:20

St. Thomas Aquinas presented five ways (quinque viae) of demonstrating God's existence through reason: from motion, from efficient causality, from contingency, from degrees of perfection, and from the governance of things toward an end. These are not "proofs" in the mathematical sense but philosophical demonstrations that show the existence of a First Cause, Necessary Being, and Intelligent Designer is the most rational conclusion from what we observe in the world.

The Psalmist writes: "The heavens shew forth the glory of God, and the firmament declareth the work of his hands." — Psalm 18:2 (Douay-Rheims numbering)

And again: "The fool hath said in his heart: There is no God." — Psalm 13:1

2. "The Bible is unreliable and full of contradictions."

Objection

The Bible was written by men, copied and translated countless times, and contains internal contradictions. It cannot be trusted as the Word of God.

Reply

The Church teaches that Sacred Scripture is inspired by God: "All scripture, inspired of God, is profitable to teach, to reprove, to correct, to instruct in justice." — 2 Timothy 3:16. The human authors wrote under the inspiration of the Holy Spirit, so that God is the principal author of Scripture.

The manuscript evidence for the New Testament is extraordinarily strong. We possess over 5,800 Greek manuscripts, more than 10,000 Latin manuscripts, and thousands more in other ancient languages — far surpassing any other ancient text. The earliest fragments date to within decades of the originals.

Apparent contradictions typically arise from failing to account for literary genre, historical context, or the distinction between different accounts of the same event told from different perspectives. The Church has always held that Scripture, properly understood in its literal and spiritual senses, is without error in what it affirms regarding faith and morals.

Our Lord Himself treated Scripture as authoritative: "The scripture cannot be broken." — S. John 10:35. And: "Till heaven and earth pass, one jot, or one tittle shall not pass of the law, till all be fulfilled." — S. Matthew 5:18

3. "The Bible alone is sufficient — sola scriptura."

Objection

Scripture alone is the sole rule of faith. All doctrine must be found explicitly in the Bible. Tradition is merely a human addition.

Reply

The doctrine of sola scriptura is itself not found in Scripture — making it self-refuting. The Bible nowhere claims to be the sole rule of faith. On the contrary, it commends Tradition alongside Scripture:

"Therefore, brethren, stand fast; and hold the traditions which you have learned, whether by word, or by our epistle." — 2 Thessalonians 2:14

"And the things which thou hast heard of me by many witnesses, the same commend to faithful men, who shall be fit to teach others also." — 2 Timothy 2:2

The Church existed and taught for decades before the New Testament was completed, and for centuries before the canon of Scripture was formally settled (at the Councils of Hippo in 393 and Carthage in 397). During that entire period, the Faith was transmitted through the living Tradition of the Apostles and their successors.

As St. Basil the Great wrote: "Of the dogmas and messages preserved in the Church, some we possess from written teaching and others we receive from the tradition of the Apostles, handed on to us in mystery. In respect to piety, both are of the same force." (On the Holy Spirit, 27.66, c. 375 A.D.)

Scripture and Tradition are not opposed but form a single sacred deposit of the Word of God, entrusted to the Church. See also Objection 20 on Tradition below.

4. "Jesus never claimed to be God."

Objection

Jesus was a great moral teacher, but He never explicitly claimed to be divine. His followers invented the idea of His divinity.

Reply

Jesus made claims that, in a Jewish context, could only be understood as claims to divinity:

"I and the Father are one." — S. John 10:30. His hearers understood this perfectly, for they immediately took up stones to kill Him for blasphemy, "because that thou, being a man, makest thyself God" (S. John 10:33).

"Before Abraham was made, I am." — S. John 8:58. Jesus here applies to Himself the divine name revealed to Moses at the burning bush ("I AM WHO AM", Exodus 3:14). Again, His hearers took up stones (S. John 8:59).

He forgave sins, a prerogative belonging to God alone: "Son, thy sins are forgiven thee." — S. Mark 2:5. The scribes correctly recognized this as a divine claim: "Who can forgive sins, but God only?" (S. Mark 2:7).

He accepted worship: When Thomas fell before Him and said, "My Lord, and my God" (S. John 20:28), Jesus did not correct him — He affirmed him.

St. Paul, writing within twenty-five years of the Crucifixion, calls Christ "God… blessed for ever" (Romans 9:5) and says He existed "in the form of God" and "thought it not robbery to be equal with God" (Philippians 2:6).

5. "The Resurrection is a myth."

Objection

The Resurrection was invented by the early Church. People do not rise from the dead; the story grew through legend and wishful thinking.

Reply

The Resurrection is the central fact of Christian faith: "And if Christ be not risen again, then is our preaching vain, and your faith is also vain." — 1 Corinthians 15:14

St. Paul's account in 1 Corinthians 15:3–8, written around A.D. 55, preserves a creedal formula that scholars date to within three to five years of the Crucifixion. This is not legend developed over centuries — it is testimony from the generation that witnessed the events. Paul lists over five hundred witnesses to the risen Christ, most of whom were still alive when he wrote and could have been questioned (1 Corinthians 15:6).

The Apostles, who fled in fear at the Crucifixion, were transformed into men willing to suffer and die for their testimony that Christ had risen. People may die for what they sincerely believe to be true; they do not die for what they know to be a fabrication.

The empty tomb was never denied by the earliest opponents of Christianity. The Jewish authorities did not claim the tomb was occupied — they claimed the body was stolen (S. Matthew 28:13), thereby conceding the tomb was empty.

The first witnesses were women (S. Mark 16:1–8; S. Luke 24:1–10), who in first-century Jewish culture were not considered credible legal witnesses. If the account were fabricated, no inventor would have chosen women as the primary witnesses.

6. "Christ never founded a visible Church."

Objection

Jesus came to establish a personal relationship between individuals and God, not an institutional Church with hierarchy, rules, and authority.

Reply

Jesus explicitly spoke of founding His Church — using the singular: "And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it." — S. Matthew 16:18

He appointed twelve Apostles (S. Mark 3:14–19), gave them authority to bind and loose (S. Matthew 18:18), to forgive sins (S. John 20:21–23), and to teach all nations (S. Matthew 28:19–20). He instituted sacraments — Baptism (S. Matthew 28:19), the Eucharist (S. Luke 22:19–20), Confession (S. John 20:23) — which require visible ministers and a visible community.

He established a procedure for settling disputes within the community: "And if he will not hear them: tell the church. And if he will not hear the church, let him be to thee as the heathen and publican." — S. Matthew 18:17. One cannot "tell the church" if the church is invisible.

St. Paul calls the Church "the pillar and ground of the truth" (1 Timothy 3:15) and compares it to a body with many members but one head (1 Corinthians 12:12–27; Ephesians 1:22–23; Colossians 1:18). This is not a loose collection of individuals but an organized, visible community.

7. "Apostolic succession is a human invention."

Objection

There is no biblical basis for the idea that bishops are successors of the Apostles with inherited authority. This is a power structure the Church invented.

Reply

Scripture shows the Apostles appointing successors and transmitting their authority. Paul and Barnabas "ordained… priests in every church" (Acts 14:22). Paul instructs Titus: "For this cause I left thee in Crete, that thou shouldest… ordain priests in every city, as I also appointed thee." — Titus 1:5. He tells Timothy: "Impose not hands lightly upon any man" (1 Timothy 5:22), indicating the power of ordination was itself handed on.

The earliest post-apostolic writings confirm this understanding. St. Clement of Rome, writing around A.D. 96 (within living memory of the Apostles), states: "Our Apostles also knew, through our Lord Jesus Christ, that there would be strife on account of the office of the episcopate. For this reason… they appointed those already mentioned, and afterwards gave instructions that when these should fall asleep, other approved men should succeed them in their ministry." (Letter to the Corinthians, 44)

St. Irenaeus of Lyons (c. A.D. 180) used the unbroken succession of bishops from the Apostles as a test of authentic teaching, tracing the line of Roman bishops from Peter to his own day.

For the sacrament itself, see Holy Orders →

8. "Peter was never given authority over the other Apostles."

Objection

Peter was just one of the twelve Apostles. The idea that he was the "first Pope" with supreme authority is a later invention with no basis in Scripture.

Reply

Christ singled out Peter repeatedly and in unmistakable terms:

"And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven." — S. Matthew 16:18–19

The "keys of the kingdom" evoke Isaiah 22:22, where the key of the house of David is given to Eliakim as a sign of viceregal authority — the office of prime minister under the king. Jesus is the King; Peter receives the keys as His chief steward.

After the Resurrection, Christ charged Peter alone with the universal pastoral office: "Feed my lambs… Feed my lambs… Feed my sheep." — S. John 21:15–17. The threefold commission mirrors Peter's threefold denial and restores him as chief shepherd of the flock.

Jesus prayed specifically for Peter's faith: "Simon, Simon, behold Satan hath desired to have you, that he may sift you as wheat: but I have prayed for thee, that thy faith fail not: and thou, being once converted, confirm thy brethren." — S. Luke 22:31–32

In every list of the Apostles in Scripture, Peter is named first (S. Matthew 10:2–4; S. Mark 3:16–19; S. Luke 6:14–16; Acts 1:13). Matthew even calls him "the first" (S. Matthew 10:2) — not first called, for that was Andrew, but first in rank.

Peter acts as spokesman and leader throughout Acts: he presides over the election of Matthias (Acts 1:15–26), preaches at Pentecost (Acts 2:14–41), and pronounces the definitive judgment at the Council of Jerusalem (Acts 15:7–11).

9. "Papal infallibility means the Pope can never be wrong."

Objection

Catholics claim the Pope is infallible — that he can never make a mistake. This is obviously absurd, since Popes have been sinners and have held wrong opinions.

Reply

This is a misunderstanding of what infallibility means. Papal infallibility does not mean the Pope is sinless (that would be impeccability) or that he is always right about everything. It means that when the Pope teaches ex cathedra — that is, when he speaks in his official capacity as pastor and teacher of all Christians, defining a doctrine concerning faith or morals to be held by the whole Church — he is preserved from error by the Holy Spirit.

The conditions for an infallible definition are strict and have been invoked rarely. The Pope must be: (1) speaking as supreme pastor and teacher (ex cathedra), (2) defining a doctrine, (3) concerning faith or morals, (4) binding the universal Church. A Pope's personal opinions, private conversations, off-the-cuff remarks, or even encyclicals do not carry the charism of infallibility unless these conditions are met.

This charism is rooted in Christ's promise that the gates of Hell would not prevail against His Church (S. Matthew 16:18) and His prayer that Peter's faith would not fail (S. Luke 22:32). It protects the Church from binding the faithful to error in matters of salvation — it does not make any individual Pope impeccable, omniscient, or beyond criticism.

10. "The Eucharist is only a symbol."

Objection

The bread and wine of Communion are symbols of Christ's body and blood. Catholics take Jesus' words too literally.

Reply

Jesus' language in instituting the Eucharist is unambiguous: "This is my body, which is given for you." — S. Luke 22:19. "This is my blood of the new testament, which shall be shed for many." — S. Mark 14:24. He says "is," not "represents" or "symbolizes."

In the Bread of Life discourse (S. John 6:48–69), Jesus insists on the literal meaning with increasing force: "I am the living bread which came down from heaven. If any man eat of this bread, he shall live for ever; and the bread that I will give, is my flesh, for the life of the world." — S. John 6:51–52. When His hearers objected, He did not soften the language — He intensified it: "Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you." — S. John 6:54. The Greek verb used (trōgō) means to gnaw or chew — as physical and literal as language can be.

Many disciples left Him over this teaching (S. John 6:67). If He had meant it symbolically, the moment to clarify was when people were walking away — yet He did not retract a word. He turned to the Twelve and asked if they too would leave.

St. Paul confirms the Real Presence: "Therefore whosoever shall eat this bread, or drink the chalice of the Lord unworthily, shall be guilty of the body and of the blood of the Lord." — 1 Corinthians 11:27. One cannot be "guilty of the body and blood" of someone by misusing a symbol.

The early Church understood this literally from the beginning. St. Ignatius of Antioch (c. A.D. 110), a disciple of the Apostle John, condemned those who "abstain from the Eucharist and from prayer, because they do not confess that the Eucharist is the flesh of our Saviour Jesus Christ" (Letter to the Smyrnaeans, 7).

11. "Confession to a priest is unnecessary — we can confess directly to God."

Objection

Only God can forgive sins. There is no need for a human intermediary; we can go directly to God in prayer.

Reply

God absolutely can and does forgive sins — and He has chosen to exercise that power through human ministers. On the evening of the Resurrection, Jesus appeared to the Apostles and said:

"As the Father hath sent me, I also send you. When he had said this, he breathed on them; and he said to them: Receive ye the Holy Ghost. Whose sins you shall forgive, they are forgiven them; and whose sins you shall retain, they are retained." — S. John 20:21–23

This is a judicial act. The Apostles are given the power both to forgive and to retain sins. In order to exercise judgment — to know whether to forgive or retain — they must hear the sins confessed. A judge who cannot hear the case cannot render a verdict.

St. James instructs the faithful: "Confess therefore your sins one to another: and pray one for another, that you may be saved." — S. James 5:16. And the early Christians practiced confession: "And many of them that believed, came confessing and declaring their deeds." — Acts 19:18

God uses human instruments throughout salvation history: Moses mediated the covenant, prophets spoke God's word, and Christ Himself — God made man — is the supreme mediator. That God uses priests to confer His forgiveness is consistent with His established pattern of working through human agents.

12. "Infant baptism has no biblical basis."

Objection

Baptism requires a personal profession of faith. Infants cannot believe, so they should not be baptized. The Bible only shows adult baptisms.

Reply

Scripture records the baptism of entire households, which in the ancient world would typically include children and infants: Lydia and "her household" (Acts 16:15), the jailer at Philippi "and all his house" (Acts 16:33), the "household of Stephanas" (1 Corinthians 1:16).

Baptism is the New Covenant counterpart to circumcision, which was performed on infants on the eighth day (Colossians 2:11–12). If God included infants in the Old Covenant, it would be strange to exclude them from the New, which is greater.

Jesus Himself welcomed children and rebuked those who tried to keep them away: "Suffer the little children to come unto me, and forbid them not; for of such is the kingdom of God." — S. Mark 10:14

Peter, at Pentecost, declared the promise to be "to you, and to your children" (Acts 2:39). Baptism remits original sin, from which infants are not exempt. The Church has baptized infants from the earliest centuries. St. Irenaeus (c. A.D. 180) speaks of the Church baptizing "infants and small children." Origen (c. A.D. 233) states that "the Church received from the Apostles the tradition of giving baptism even to infants."

For the sacrament of Baptism, see Baptism →

13. "Catholics worship Mary."

Objection

Catholics give Mary titles like "Queen of Heaven," pray to her, and treat her as a goddess. This is idolatry and violates the First Commandment.

Reply

The Catholic Church has always clearly distinguished between latria (adoration or worship), which is due to God alone, and dulia (veneration or honour), which may be given to the saints. The special veneration given to Mary is called hyperdulia — a higher degree of honour than given to other saints, but infinitely less than the worship owed to God.

Honouring Mary is biblical. The angel Gabriel greets her with unique honour: "Hail, full of grace, the Lord is with thee: blessed art thou among women." — S. Luke 1:28. Elizabeth, filled with the Holy Spirit, exclaims: "Blessed art thou among women, and blessed is the fruit of thy womb." — S. Luke 1:42. Mary herself prophesies: "From henceforth all generations shall call me blessed." — S. Luke 1:48. Catholics fulfill this prophecy; those who refuse to honour her do not.

To ask Mary to pray for us is no different in principle from asking a friend on earth to pray for us — except that Mary is alive in Christ in Heaven, closer to God, and free from sin. When we say "pray for us sinners," we are asking for her intercession, not worshipping her.

The title "Queen" reflects the Old Testament practice in which the queen mother (gebirah) held a position of honour in the Davidic kingdom. As Christ is the King in the line of David, Mary is the Queen Mother.

For a deeper treatment, see The Assumption of Mary →

14. "Praying to saints is unbiblical."

Objection

There is only one mediator between God and man — Christ (1 Timothy 2:5). Praying to dead saints is necromancy, forbidden in the Old Testament.

Reply

The saints in Heaven are not dead — they are more alive than we are. Christ declares: "God is not the God of the dead, but of the living." — S. Matthew 22:32. And: "He that believeth in me, although he be dead, shall live." — S. John 11:25

Asking the saints to pray for us does not contradict Christ's unique mediation any more than asking a living friend to pray for you does. St. Paul repeatedly asks others to pray for him (Romans 15:30; 2 Thessalonians 3:1; Colossians 4:3). 1 Timothy 2:1 urges "supplications, prayers, intercessions, and thanksgivings be made for all men." If the living can intercede for one another, why not the saints who are alive in Christ?

The Book of the Apocalypse (Revelation) shows the saints in Heaven actively presenting the prayers of the faithful to God: "And the smoke of the incense of the prayers of the saints ascended up before God from the hand of the angel." — Apocalypse 8:4. The twenty-four elders hold "golden vials full of odours, which are the prayers of saints" (Apocalypse 5:8).

In 2 Maccabees 15:14, the deceased prophet Jeremias is seen praying for the people of Israel — a clear instance of a holy person interceding for the living from beyond this world.

Asking the saints to pray for us is simply asking fellow members of the Body of Christ, who are alive in Heaven, to pray for us. There is no conjuring, no séance, no divination.

15. "The Immaculate Conception contradicts Scripture."

Objection

The Bible says "all have sinned" (Romans 3:23). Mary was just an ordinary woman. The idea that she was conceived without sin has no biblical support.

Reply

The Immaculate Conception does not mean Mary saved herself. It means God, in view of the merits of Christ, preserved her from original sin from the first moment of her conception — a singular grace and privilege.

Romans 3:23 ("for all have sinned") is a general statement about humanity's condition, not an exhaustive catalogue that admits no exceptions. Christ Himself is human and did not sin. Infants who die before the age of reason have not personally sinned. The verse describes the universal need for redemption, which Mary also needed — and received, in an anticipatory way, at the moment of her conception.

The angel's greeting to Mary is telling: "Hail, full of grace" (kecharitōmenē) — S. Luke 1:28. This is a perfect passive participle indicating a completed state. Mary was already "fully graced" before the Annunciation. The greeting replaces her name, as though "Full of Grace" is her identity.

Mary is the New Eve, as the Fathers consistently taught. St. Irenaeus (c. A.D. 180) wrote: "The knot of Eve's disobedience was untied by Mary's obedience." Just as Eve was created without sin and then fell, Mary was preserved without sin and remained faithful.

It was fitting that the vessel chosen to bear the Son of God in her womb — the new Ark of the Covenant — should be free from all stain of sin. The original Ark was overlaid with pure gold and no unclean thing could touch it. How much more fitting that the living Ark, who carried not the tablets of the Law but the Lawgiver Himself, should be immaculate.

16. "We are saved by faith alone — sola fide."

Objection

Ephesians 2:8–9 says we are saved by grace through faith, "not of works." Catholics add works to salvation, contradicting the Gospel of grace.

Reply

The only place in the entire Bible where the phrase "faith alone" (sola fide) appears is in James 2:24 — and it denies it: "Do you see that by works a man is justified; and not by faith only?" — S. James 2:24

Catholics absolutely affirm that we are saved by grace. No one can earn or merit salvation on their own. But grace, received through faith, must bear fruit in works of love — otherwise faith is dead: "For even as the body without the spirit is dead; so also faith without works is dead." — S. James 2:26

Ephesians 2:8–9 excludes boasting, not obedience. The very next verse says: "For we are his workmanship, created in Christ Jesus in good works, which God hath prepared that we should walk in them." — Ephesians 2:10. Grace produces works; works are the evidence of living faith.

Jesus Himself teaches that works matter for salvation. At the Last Judgment, He separates the saved from the damned based on works of mercy: "Come, ye blessed of my Father… for I was hungry, and you gave me to eat." — S. Matthew 25:34–36. And: "Not every one that saith to me, Lord, Lord, shall enter into the kingdom of heaven: but he that doth the will of my Father." — S. Matthew 7:21

St. Paul, whom Protestants cite for sola fide, also says: "And if I should have all faith, so that I could remove mountains, and have not charity, I am nothing." — 1 Corinthians 13:2. And: "For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision: but faith that worketh by charity." — Galatians 5:6. Faith that works through love — this is the Catholic position.

17. "Purgatory is not in the Bible."

Objection

The word "Purgatory" never appears in Scripture. It is a medieval invention designed to frighten people and raise money for the Church.

Reply

The word "Trinity" never appears in Scripture either, yet the doctrine is clearly taught there. The absence of a word does not mean the absence of the reality.

Scripture teaches a purification after death. In 2 Maccabees 12:42–46, Judas Maccabeus orders sacrifice and prayer for soldiers who died wearing pagan amulets: "It is therefore a holy and wholesome thought to pray for the dead, that they may be loosed from sins." — 2 Maccabees 12:46. Praying for the dead implies they are in a state where prayer can help them — neither in Heaven (where they need no help) nor in Hell (where no help avails).

St. Paul speaks of a purifying fire: "If any man's work burn, he shall suffer loss; but he himself shall be saved, yet so as by fire." — 1 Corinthians 3:15. This describes a person who is saved but only after a painful purgation.

Jesus speaks of sins that will be forgiven neither "in this world, nor in the world to come" (S. Matthew 12:32), implying that some sins can be forgiven in the next world — an implication that points directly to Purgatory.

The early Church prayed for the dead from the beginning. Inscriptions in the Roman catacombs from the second and third centuries include prayers for the deceased. Tertullian (c. A.D. 211) speaks of annual offerings for the dead. St. Augustine (c. A.D. 421) prayed for his mother Monica after her death.

For the full doctrinal treatment, see Purgatory →

18. "Indulgences are selling forgiveness."

Objection

The medieval Church sold indulgences for money, and the practice proves the Church is corrupt. Buying your way out of punishment is unbiblical.

Reply

An indulgence is a remission of the temporal punishment due to sins that have already been forgiven. It is not the forgiveness of sin itself (that comes through the Sacrament of Penance) and it cannot be purchased.

The Church's power to grant indulgences flows from Christ's grant of the power to bind and loose (S. Matthew 16:19, 18:18). The spiritual treasury of the Church — the infinite merits of Christ and the superabundant merits of the saints — can be applied to the faithful by the authority of the Church to reduce the temporal punishment they would otherwise undergo in Purgatory.

Were there abuses in the late medieval period? Yes — and the Church herself condemned them. The Council of Trent explicitly forbade all financial transactions connected with indulgences: "All evil gains for the obtaining of them be wholly abolished." The abuse of a practice does not invalidate the practice itself, any more than counterfeit money proves that all currency is fraudulent.

Today, indulgences are obtained through prayer, works of charity, and acts of penance — never through payment. The conditions typically include sacramental confession, Eucharistic Communion, prayer for the Pope's intentions, and the specific work prescribed.

For a detailed treatment of indulgences, see On Indulgences →

19. "Religious images and statues are idolatry."

Objection

Exodus 20:4 forbids the making of graven images. Catholics fill their churches with statues, icons, and paintings, violating the Second Commandment.

Reply

The prohibition in Exodus 20:4–5 is against making images to worship them as gods: "Thou shalt not make to thyself a graven thing… thou shalt not adore them, nor serve them." The sin condemned is idolatry — worshipping a created thing instead of God — not the making of images as such.

God Himself commanded the making of religious images elsewhere in Scripture. He ordered Moses to make two golden cherubim for the Ark of the Covenant (Exodus 25:18–20). He commanded the making of a bronze serpent to be lifted up for the healing of the people (Numbers 21:8–9). If all images were forbidden, God would be contradicting Himself.

Catholics do not worship statues or images. A statue of a saint is like a photograph of a loved one — it is an aid to memory and devotion, not an object of worship. The honour given to the image passes to the person represented, not to the material object.

The Incarnation itself transformed the relationship between God and images. The invisible God made Himself visible in Christ: "He that seeth me seeth the Father also." — S. John 14:9. Because God took on visible, material form, He can be represented in art. As St. John Damascene argued: "Previously God, who has no body and no face, absolutely could not be represented by an image. But now that He has made Himself visible in the flesh and has lived with men, I can make an image of what I have seen of God."

20. "Catholic Tradition is merely human tradition."

Objection

Jesus condemned human traditions in Mark 7:8: "Leaving the commandment of God, you hold the tradition of men." Catholic traditions are exactly the kind of human additions Jesus rejected.

Reply

Jesus in Mark 7 condemns human traditions that contradict God's commandments — specifically, the Pharisees' practice of using the corban oath to evade the duty of honouring one's parents. He does not condemn all tradition, only traditions that nullify the Word of God.

Sacred Tradition (with a capital T) is not a human invention. It is the living transmission of the Word of God entrusted by Christ and the Holy Spirit to the Apostles, handed on to their successors in its full purity. The Gospel was preached before it was written; the Tradition preceded the text.

St. Paul explicitly commands fidelity to Tradition: "Therefore, brethren, stand fast; and hold the traditions which you have learned, whether by word, or by our epistle." — 2 Thessalonians 2:14. Note: "by word" — oral tradition — stands alongside "our epistle" — written Scripture — as equally authoritative.

"Now I praise you, brethren, that in all things you are mindful of me: and keep my ordinances [paradoseis — traditions] as I have delivered them to you." — 1 Corinthians 11:2

Many foundational Christian beliefs are preserved in Tradition and not stated explicitly in Scripture: the canon of Scripture itself (which books belong in the Bible), the doctrine of the Trinity as defined at Nicaea, Sunday worship replacing the Sabbath, and the perpetual virginity of Mary. Christians who claim to follow "the Bible alone" unknowingly rely on Tradition for the very Bible they hold.
