The eucharistic bread and wine are real bread and wine, . . nonetheless different from our ordinary bread and wine, for they are restored to their true end, they secretly justify and hallow all the food of this world by the promise of the Messianic banquet which they carry.
It is the same with Sunday which restores time to its true end, of doxological duration, and secretly it justifies and hallows all the other days.
—Jean-Jacques von Allmen, Worship: Its Theory and Practice, 223-4
