The three Gospel narratives of the Last Supper are absolutely consistent. Matthew: 26:26 "This is My Body." 26:27 "This is My Blood…" Mark: 14:22 "This is My Body." 14:24 "This is My Blood…" Luke: 22:19 "This is My Body." 22:20 "This … is the New Covenant in My Blood." Jesus' next words instituted the Catholic priesthood: Lk 22:19 "Do this in remembrance of Me."
Jesus assured the Apostles that the Holy Eucharist is a reflection of the heavenly banquet. Mt 26:29 "I tell you I shall not drink again of this fruit of the vine until that day when I drink it new with you in my Father's kingdom."
After His resurrection, Jesus walked with two disciples to Emmaus. When they arrived, He celebrated the Holy Sacrifice of the Mass for them; Lk 24:30 "While He was at table with them, He took the bread and blessed, and broke it, and gave it to them."
I KNOW what Communion is HOWEVER it is NOT a requirement to be saved. Christ clarified that on the cross. He told the thief next to him, he would be with Him in paradise. Thief was NOT baptized, nor did he have communion. So unless Christ is a liar(unlikely) this should clarify that Communion is NOT a requirement for eternal life.
