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.
Raphael, Disputation of the Holy Sacrament (1509–1510), Stanza della Segnatura, Vatican City
"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
