The following video has some great Biblical exegesis as to why the Eucharist is literal, not figurative. Among other things, it compares the “bread of life discourse” in John 6, to other Bible passages where Jesus was speaking figuratively, people thought he was speaking literally or they did not understand him, and he corrected them (“We brought no bread,” “I am the door,” “Destroy this temple and I will raise it in three days.”). No correction happened in John 6 when the people indicated that he was speaking literally, but correction happend at those other times.
Plus, in every other passage regarding the Eucharist (ie, Last Supper, Paul’s admonition at 1 Cor 11), there is no indication that that the Eucharist was figurative. 1 Cor 11 is especially interesting to me. Since St. Paul was correcting the Corinthians anyway for the way they were treating the Lord’s Supper, it would have been a good time to explain or at least indicate somehow that it was not literal. But he didn’t do that.
I don’t know who this guy his, but I’ve watched a number of his videos. The name of his YouTube channel is “How To Be Christian.” He argues each topic thoroughly, and completely from the Bible. Check him out and see if you agree.
