I am the vine, I am a shepherd (not a carpenter?), a stone the builder’s rejected, a door to a sheepfold, true bread from heaven, high priest, Bright and Morning Star. Symbols. Many names are prophetic. One is ultimate, the Son of God. Just saying that we do not eat His flesh or drink His blood. A wafer and wine do not contain His DNA and His resurrected body would not be compatible with ours.
Also, at that point the apostles would not have been asked to break God’s law.
