They did read from 1 Corinthians... Right before passing each emblem
But Corinthians is not part of the gospels... Supposed first hand accounts (if you believe in the Bible) of the apostles who lived along side Jeseus and witnessed his ministry and death.
Early on in the talk, our speaker directed us to Luke 22:19 and began reading. When he stopped at the end of v. 20, my SO leans over and whispers "Guess he needed to stop before he got the verse about Judas being there", and smiled. Later on when the speaker directed us to the verses to be read while the emblems were passes, my SO leans over again and says "yeah, because why would we want to read it from the Gospels?" and proceeded to look at the Matt - John accounts, while the speaker read from 1 Cor.
