Using the Bible, something which should be taken into account; The True Presence and the Greek Word “trogo” In John Chapter Six.
“Jesus therefore said to them, Amen, amen I say to you, Unless you eat (φάγητε | phago) the flesh of the Son of man, and drink his blood, you shall not have life in you. He that eateth (τρώγων | trogo) my flesh, and drinketh my blood, hath life everlasting: and I will raise him up in the last day. For my flesh, is meat in deed: and my blood is drink in deed: He that eateth (τρώγων | trogo) my flesh, and drinketh my blood, abideth in me, and I in him. As the living father hath sent me, and live by the father: and he that eateth (τρώγων | trogo) me, the same also shall live by me. This is the bread that came down from heaven. Not as your fathers did eat (ἔφαγον | (e)phago) Manna, and died. He that eateth (τρώγων | trogo) this bread, shall live for ever.” (John 6, 53-58).
Throughout the sacred Scriptures we find many examples of where the English does not render the complete and full meaning of the Greek. This is especially true in the Greek word “trogo” (τρώγων) found in John Chapter six. The word trogo (τρώγων) is translated in most English versions of the Bible as simply “eat” or “eateth.” When we examine the Greek meaning of the word, we realize that it is a very descriptive word, and is more accurately rendered in the concept of aggressively and loudly munching, gnawing and chewing, as a animal would eat.
The inspired Apostle John specifically chose to use this highly descriptive word, rather than the generally used Greek words “esthio” (ἐσθίω,v) or “phago”(ἔφαγον) (both of which simply mean to eat), for a reason. St. John was attempting to drive home the thought of a very real and physical eating of actual flesh. His inspired word usage clearly shows that Christ was not speaking figuratively, Christ was in fact commanding his listeners to gnaw and chew his flesh. The Jews understood that Christ was being literal, and were disgusted at the thought (vs.52), many of Christ's own disciples were so shocked and dismayed by his words that they left him (v.66).
From the Greek we see the very literal meaning of our savior's words, The bread he was offering them is indeed the body blood soul and divinity of Jesus Christ.
