First, you have assumed I know little of the Catholic Church and it’s teachings. I’ve studied your teachings for years and when I study it, I check the teachings with my Bible in hand. I highly suggest that instead of accepting everything ANY religious teacher says, to search God’s Word to insure you are receiving His teachings and not that of fallen man. Now, concerning communion:
Biblical Disharmony
When John 6:53 is interpreted literally it is in disharmony with the rest of the Bible. “Unless you eat the flesh of the Son of Man and drink His blood, you have no life in you,” gives no hope of eternal life to any Christian who has not consumed the literal body and blood of Christ. It opposes hundreds of Scriptures that declare justification and salvation are by grace through faith in Christ.
For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God—not by works, so that no one can boast. 8
It Produces A Dilemma
It is stated that the “eating and drinking” in verse 6:54 and the “believing” in verse 6:40 produce the same result - eternal life. If both are literal we have a dilemma. What if a person “believes” but does not “eat or drink”? Or what if a person “eats and drinks” but does not “believe?” This could occur any time a non-believer walked into a Catholic Church and received the Eucharist. Does this person have eternal life because he met one of the requirements but not the other? The only possible way to harmonize the interpretation of these two verses is to accept one as figurative and one as literal.
It Was Figurative in the Old Testament
The Jews were familiar with “eating and drinking” being used figuratively in the Old Testament to describe the appropriation of divine blessings to one’s innermost being. It was God’s way of providing spiritual nourishment for the soul (Isaiah 55:1-3; Ezekiel 2:8, 3:1).
When your words came, I ate them; they were my joy and my heart’s delight, for I bear your name, O Lord God Almighty. 9
Jesus Confirmed It To Be Figurative
Jesus informed His disciples there were times when He spoke figuratively and He often used that type of language to describe Himself. The Gospel of John records seven figurative declarations Jesus made of Himself: “the bread of life” (6:48), “the light of the world” (8:12), “the door” (10:9), “the good shepherd” (10:11), “the resurrection and the life” (11:25), “the way, the truth and the life” (14:6), and “the true vine” (15:1). He also referred to His body as the temple (2:19).
"Though I have been speaking figuratively, a time is coming when I will no longer use this kind of language but will tell you plainly about my Father. 10
