The liturgy of my Episcopal church goes like this:
“Jesus, our Passover is sacrificed for us. Therefore, let us keep the feast (communion.)”
I’ve discussed this with my priest, and it does seem to be Anglican theology that Jesus’ death is for the forgiveness sins.
But I don’t agree with this idea. As has been pointed out, Jesus had the power to forgive sins, so why would He need to undergo death by torture in order to persuade YHWH to forgive? It just doesn’t make sense.
Another issue is that our Creator is just, and having one person undergo torture for another’s shortcomings is not just.
My opinion is that Jesus was setting an example for mankind as to the extremes that YHWH expects men to go in following His Law. Jesus practiced what He preached, loving His enemies, returning good for evil, turning the other cheek, and, above all, trusting in His Father. His following the Law perfectly resulted in His brutal treatment, but even then He would not waver.
This is a profound teaching, and we should all prepare ourselves to follow His example if called to so so.
