The only really effective apologia

The only really effective apologia for Christianity comes down to two arguments, namely the saints the Church has produced and the art which has grown in her womb. Better witness is borne to the Lord by the splendor of holiness and art which have arisen in the community of believers than by the clever excuses which apologetics has come up with to justify the dark sides which, sadly, are so frequent in the Church’s human history

—Joseph Cardinal Ratzinger
