Interesting that when Christ says "He who eats (trogon) My flesh and drinks My blood has eternal life . . ." He uses the Greek word trogon which means, "to gnaw, munch or crunch." Trogon is also used in the context of eating flesh (sarx). This doesn't seem to be the words of merely symbolism. Otherwise, He would have used the word phago as He does when speaking to the Israelites about eating the manna.John 6:54 - "He who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day."
