ISB ~ 1 Corinthians 11 v23

I received from the Lord:Paul learned of the Last Supper through the Church’s liturgical tradition stretching back to Jesus and the first apostles. His account agrees in substance with the narratives of the Gospels, especially Luke’s version (Lk 22:19-20). Paul is confident that divine revelation is safely passed on through the tradition of the Church.

he was betrayed:By Judas Iscariot (Mk 14:43-46; Jn 13:26-30).
