Rorate Caeli

The first "liturgists" - I

We allow the vestments, altars, and candles to remain in use until they are used up or it pleases us to make a change. But we do not oppose anyone who would herein do otherwise. In the true Mass, however, of real Christians, the altar could not remain where it is and the priest must always face the people as doubtless Christ did in the last Supper. But let that await its own time.
Martin Luther
