The reason these things, brothers and sisters, are called sacraments is that in them one thing is seen, another is to be understood. What can be seen has a bodily appearance, what is to be understood provides spiritual fruit. So if you want to understand the body of Christ, listen to [Paul] telling the faithful, You, though, are the body of Christ and its members (1 Cor 12:27). So if it’s you that are the body of Christ and its members, it’s the mystery meaning you that has been placed on the Lord’s table; what you receive is the mystery that means you. It is to what you are that you reply Amen, and by so replying you express your assent. What you hear, you see, is The body of Christ, and you answer, Amen. So be a member of the body of Christ, in order to make that Amen true.
So why in bread? Let’s not bring anything of our own to bear here, let’s go on listening to [Paul] himself, who said, when speaking of this sacrament, One bread, one body, we being many are (1 Cor. 10:17). Understand and rejoice. Unity, truth, piety, love. One bread; what is this one bread? The one body which we, being man, are. Remember that bread is not made from one grain, but from many. When you were being exorcised, it’s as though you were being ground. When you were baptized it’s as though you were mixed into dough. When you received the fire of the Holy Spirit, it’s as though you were baked. Be what you can see, and receive what you are.
