Nay, dear sir, if I utilizeth brevity and say “Jesus inaugurated the Eucharist and told all of us, His followers, to eat of His body and to do this in memory of Him”
Then you would say “that’s not enough, give me more information”
And there would be post 38 - giving you the exhaustive evidence from the Bible that Jesus told us to celebrate the Eucharist, and to eat of His body.
Ok. I’ll use little words. Don’t clog up the rest of FR with your crap.
