For God’s sake don’t pay any attention to John 6, 1st Cor 10:16, & 11:23-29 or any of the last supper passages… (like Matt 26:26-28, Mark 14:22-24, Luke 22:17-20 and 24:30-35)
Oh yeah…and read around Matthew 16:13-19, John 20:24 & 25,
Luke 22:31-32, and John 21:15-17 because you might just see the NT basis for the things that the Catholics believe.
Then ignore passages like James 5:13-16 because it fits into the context of John 20:19-23 and 2nd Corinthians 5:17-20.
Please feel free to pick any one set of topical verses and have at it until you feel like you’ve exhausted that topic then pick up another or spin off your own threads.
Remember what was said of the early Christians by those who persecuted them: “See how these christains love one another.”
