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. If the Church is to continue to transform and humanize the world, how can she dispense with beauty in her liturgies, that beauty which is so closely linked with love and with the radiance of the Resurrection? No, Christians must not be too easily satisfied. They must make their Church into a place where beauty — and truth — is at home. Without this the world will become the first circle of hell…. A theologian who does not love art, poetry, music and nature can be dangerous. Blindness and deafness toward the beautiful are not incidental: they necessarily are reflected in his theology.
Joseph Cardinal Ratzinger (1985)
