Interesting that you limit God to one means. I see him as able to bestow his gifts by any and all means he chooses, not merely by repentant faith.
Sorry but you will not find anyone converted in the NT who did not repent and believe on the Lord Jesus Christ to save them, nor will you find souls being born again by taking part in the Lord's Supper (though you will find some dead because they did so hypocritically).
That you cannot even accept this is consistent with your recourse to rejecting contextual systematic theology as "jumping thru hoops."
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.

Never said I believed that. RCC teaches that rebirth takes place at baptism.

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.
