St. Augustin, the bishop of Hippo said about Taizé songs:

So now, my brethren, let us sing, not to delight our leisure, but to ease our toil. In the way that travellers are in the habit of singing, sing, but keep on walking. (…) If you are going onward, you are walking; but always go onward in goodness, onward in the right faith, onward in good habits and behavior. Sing, and walk onwards.

Modo ergo, fratres mei, cantemus, non ad delectationem quietis, sed ad solacium laboris. Quomodo solent cantare viatores; canta, sed ambula; laborem consolare cantando, pigritiam noli amare; canta et ambula. (…) Tu Si proficis, ambulas, sed in bono profice, in recta fide profice, in bonis moribus profice: CANTA ET AMBULA.
(S. Augustinus, Sermo 256, 3)
