Christ used unleavened bread simply because it was at that moment on the paschal table. Wine, and no other liquid, is to be used ( Matthew 26:26-29 ). Believers "feed" on Christ's body and blood, (1) not with the mouth in any manner, but (2) by the soul alone, and (3) by faith, which is the mouth or hand of the soul.

This is a permanent ordinance in the Church of Christ, and is to be observed "till he come" again.
