Hi, GTW27.
Thanks for bringing this up. Let me comment on Jesus word's during the Last Supper.
What festivity were Jesus and his disciples celebrating?
The Passover. The first Passover implied eating a lamb and applying blood to the doors. The Passover implied going from the condition of slavery in Egypt to the condition of free men. Blood, in Jewish imagery, meant life. That's why it was considered sacred.
So,
what Jesus did was to apply those symbols to his mission. The new, spiritual Passover, meant to go from the slavery of sin to a new life free of sin. Jesus was giving us life... and although the
symbol of such life is his blood, in
reality, such life, as we have seen in other texts, is in his
WORDS. Specifically, in obeying his words, in
knowing God.
In summary. In the Last Supper, when referring to his body as the bread and to his blood as the wine...
- Jesus was not giving a sermon nor setting an example on how God forgives sins. We already reviewed 3 parables and the Lord's Prayer where He specifically addressed the subject. We have mentioned that Jesus never requested any sinner to believe in a substitutionary atonement as a requisite to be healed or forgiven
- Jesus was not saying that the purpose of his mission was to perform a blood atonement. In other texts of the Gospel we will review what He Himself claimed ot be his mission.
- The Passover was taking place, and the symbolism of body and blood was appropriate.
- The disciples didn't take Jesus words as meaning a requisite for forgiveness. This is why they didn't preach that doctrine after that Last Supper... nor after, crucifixion, resurrection and Pentecost.
