“I am the liuing bread, which came downe from heauen. If any man eate of this bread, he shall liue for euer: and the bread that I will giue, is my flesh, which I will giue for the life of the world.”
1611 King James Version (KJV)
6:51 If any eat of this bread - That is, believe in me: he shall live for ever - In other words, he that believeth to the end shall be saved. My flesh which I will give you - This whole discourse concerning his flesh and blood refers directly to his passion, and but remotely, if at all, to the Lord's Supper.
