In the first place, in order that we might safely and happily attain to a true and free knowledge of this sacrament, we must be particularly careful to put aside whatever has been added to its original simple institution by the zeal and devotion of men: such as vestments, ornaments, chants, prayers, organs, candles, and the whole pageantry of outward things… All the rest is the work of man, added to the word of Christ and the mass can be held and remain a mass just as well without them.
