It is no accident that much of the most beautiful art and music in the Western tradition has been religious, and that a good deal of that has been produced for use in the sacred liturgy.William Schaefer
Evangelization isn’t just giving people a set of propositions, or a rulebook to follow. It’s inviting them into a relationship with the living God. But first we must get their attention. Human beings are by nature drawn to beauty. If we want people to fall in love with God, we must give them a glimpse of His loveliness.
Of course, love is the primary way we do this. But it’s a mistake to think that the outward forms of the Faith—liturgy, music, art, architecture—are superfluous. Nothing could be farther from the truth. These outward manifestations of beauty reveal something of the great love of God for us. They are also a sign of our love for Him.
There’s so much ugliness and banality all around us—it’s the hallmark of our post-Christian age. The Church must provide a refuge from all that.
