Who'd partake of the Eucharist if they didn't believe in Christ? (I mean in those days, not present days where some do so to profane the Holy Sacrifice of the Mass or steal the precious body of the Lord for black masses.) Faith in Jesus and repentance for one's sins don't preclude Jesus from manifesting himself in the Eucharist as he said. If Jesus chooses to bring us additional grace via his presence in the Eucharist, I believe he is fully capable of doing so. You are free to disbelieve if you choose.
nor will you find souls being born again by taking part in the Lord's Supper
Never said I believed that. RCC teaches that rebirth takes place at baptism.
That you cannot even accept this is consistent with your recourse to rejecting contextual systematic theology as "jumping thru hoops."
Actually I was not willing to waste more of your time or mine trading scriptures back and forth because it appears likely we'd reject each other's interpretations. You are free to disbelieve the Lord's words about his presence in the Eucharist. For me, discounting his words takes more faith than simply believing what he said, therefore my reference to hoops. If my choice of words was insulting to you, I apologize. Peace be with you.

The context continues to be that of how one receives life in them, versus have no life, (Jn. 6:53) and it remains that it is not by taking part in the Lord's supper, but by repentance and faith in the gospel message. This will result in doing more things, but this is not how one obtains life in them

No one is discounting his words, but what is discounted is proven principles of sound exegesis, as such "plain meaning" literalism would also literally turn John the Baptist into Elijah, ("this is Elias:" Mt. 11:14; Mk. 9:11-13) or believers into literal water fountains, (Jn. 7:37) and require actual cutting off of one's hand if it causes you to sin.(Mk. 9:43) Which makes a mockery of Biblical hermeneutics. Meanwhile RCs will expend great effort in trying to disallow the normal "plain meaning" of Mt. 1:25 from even possibly meaning that.
