It Teaches Less one religion than a family of them. Common threads: an ultimate reality (Brahman), conceived by some schools as an impersonal Absolute with which the soul is finally identical, by others as a personal Lord served by devotion; countless gods and avatars as manifestations; the soul bound to samsara, the wheel of rebirth, driven by karma; liberation (moksha) sought through knowledge, works, or devotion across many lifetimes.
The Church Affirms A profound and ancient testimony that this visible world is not the whole of reality; disciplined asceticism, meditation, and the instinct that man's restlessness seeks the divine (Nostra Aetate 2). The devotional schools' hunger for a gracious, personal Lord is a true seed of the Word.
It Contradicts The first article of the Creed and the last. Against pantheism and monism, the Church teaches that God is really distinct from His creation — the world is His work, not His substance, and the soul is His creature, never to “become” God by nature. Against the many gods and avatars, there is one God and one Incarnation, unique and unrepeatable. Against reincarnation, Scripture is explicit: “it is appointed unto men once to die, and after this the judgment” (Heb. 9:27) — each person is a unique creation, not a recycled spark. And against karma as cosmic bookkeeping, the Gospel proclaims what no law of karma can conceive: forgiveness — guilt not worked off across lifetimes but freely remitted through the Cross.

Buddhism
Siddhartha Gautama, the Buddha, India · the Pali Canon and later sutras
It Teaches The Four Noble Truths: existence is suffering; suffering is caused by craving; craving can be extinguished; the Eightfold Path extinguishes it. There is no creator God and — the doctrine of anatta — no permanent self or soul at all; what reincarnates is a stream of consequences, not a person. The goal is nirvana: the “blowing out” of craving and of the illusion of self, escaping the wheel of rebirth.
The Church Affirms An honest diagnosis half-right: that disordered desire enslaves, that the world cannot satisfy the heart, that discipline, detachment, and compassion are necessary — truths every Catholic ascetic would recognize (Nostra Aetate 2 acknowledges Buddhism's testimony to the world's “radical insufficiency”).
It Contradicts Almost every remaining article. It is, in its classical form, atheistic: no Creator, no providence, no prayer that is heard. It denies the immortal soul the Church defined at Lateran V — there is no one to save. Its remedy for suffering is the extinction of desire; the Gospel's is the redemption of the sufferer — Christ did not teach escape from the Cross but took it up, and made suffering itself, offered in love, redemptive (Col. 1:24; see the Mystical Body). And where nirvana is the cessation of the self, heaven is its consummation: the beatific vision is not a candle blown out but a face finally seen (1 Cor. 13:12). Salvation, finally, is not self-achieved enlightenment but grace: “without me you can do nothing” (John 15:5).

Sikhism
Guru Nanak, Punjab · the Guru Granth Sahib
It Teaches One formless God, remembered through His Name; equality of all; honest work and charity; the soul subject to karma and rebirth until union with God; ten Gurus, the scripture itself now Guru.
It Contradicts The Incarnation expressly — God, it holds, does not take human form — along with the Trinity, the Cross, and salvation by grace; and it retains reincarnation against Hebrews 9:27. Its noble monotheism and ethics are, from the Church's view, natural religion at its best, still awaiting the Gospel.

Taoism, Confucianism, Shinto
Lao-tzu; Confucius (c. 500 BC); Japan's native tradition
It Teaches Taoism: harmony with the impersonal Way (Tao) beneath all things. Confucianism: less a religion than a moral order — filial piety, ritual propriety, the cultivation of virtue. Shinto: reverence of the kami, spirits of nature, ancestors, and nation, with purity rites but no creed, moral code of salvation, or doctrine of the hereafter.
It Contradicts Chiefly by what it lacks: an impersonal Tao or a multitude of kami is not the living, personal Creator; ancestor veneration shades into worship owed to God alone; and Confucian ethics, admired by the Church's own missionaries, seeks virtue without grace, sanctity's scaffolding without its life. These traditions show how far natural wisdom can climb — and where it stops.
