Christ - Body and Blood

As to the second meaning: He said, "I am the living bread which came down from heaven." It was not the body of Christ which came from heaven. His body came from the womb of Mary, but the Christly perfections descended from heaven; the reality of Christ came down from heaven. The Spirit of Christ and not the body descended from heaven. The body of Christ was but human. There could be no question that the physical body was born from the womb of Mary. But the reality of Christ, the Spirit of Christ, the perfections of Christ all came from heaven. Consequently, by saying He was the bread which came from heaven He meant that the perfections which He showed forth were divine perfections, that the blessings within Him were heavenly gifts and bestowals, that His light was the light of Reality. He said, "If any man eat of this bread, he shall live for ever." That is to say, whosoever assimilates these divine perfections which are within me will never die; whosoever has a share and partakes of these heavenly bounties I embody will find eternal life; he who takes unto himself these divine lights shall find everlasting life. How manifest the meaning is! How evident! For the soul which acquires divine perfections and seeks heavenly illumination from the teachings of Christ will undoubtedly live eternally. This is also one of the mysteries of sacrifice.

For instance, it is recorded in the Gospel that Christ said, "I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever." He also said, "This [wine] is my blood ... which is shed for many for the remission of sins." These verses have been interpreted by the churches in such a superstitious way that it is impossible for human reason to understand or accept the explanation.
