Apologetics

Apologetica · The Reasoned Defense of the Faith

Apologetics is not argument for argument's sake. It is an act of charity — a willingness to give an honest account of what we believe and why.

"But sanctify the Lord Christ in your hearts, being ready always to satisfy every one that asketh you a reason of that hope which is in you." — 1 S. Peter 3:15, Douay-Rheims
