If the suffering servant in Isaiah 53 is Israel, then it means God was the instigator of the suffering upon Israel.
[Isa 53:4 KJV] 4 Surely he (Israel) hath borne our griefs, and carried our sorrows: yet we did esteem him (Israel) stricken, smitten of God, and afflicted.
[Isa 53:6 KJV] 6 All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him (Israel) the iniquity of us all.
[Isa 53:10 KJV] 10 Yet it pleased the LORD to bruise him (Israel); he hath put [him] (Israel) to grief: when thou shalt make his soul an offering for sin, he shall see [his] seed, he shall prolong [his] days, and the pleasure of the LORD shall prosper in his hand.
There is no other greater suffering in the modern era that the Jews have suffered than the Holocaust. Between 5 to 6 million Jews were killed, roughly one third of the entire Jewish worldwide population at that time. Millions more had endured the concentration camps and even tortured.
So, it would mean God was involved in causing the Jews to suffer during the Holocaust.
There are several problems with this. The immediate problem is it puts God as the institagor of evil, which is contrary to God being an omnibenevolent God.
The person who first proposed this idea was Ignaz Maybaum.
He is most frequently remembered for his controversial view in The Face of God After Auschwitz (1965) that the suffering of Jews in the Holocaust was vicarious atonement for the sins of the rest of the world. He was connecting the Jewish people to the figure of the "suffering servant" of Isaiah 52 and 53 in the Tanakh (the Christian Old Testament). In the same work he employed Christian imagery, speaking of Auschwitz as the new Golgotha and the gas chambers as replacing the cross.
His comparison of the Jews dying in the Holocaust and Jesus dying on the cross has several problems.
1. In the Jewish law, the animal that bore sin had to be perfect. Jews are not sinless, whereas Jesus was sinless.
[1Pe 1:19 KJV] 19 But with the precious blood of Christ, as of a lamb without blemish and without spot:
2. The Jews had no concept they were suffering for the sins of the world. Jesus knew he would be suffering for the sins of the world.
[Mat 16:21 KJV] 21 From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day.
3. The Jews went to concentration camps and died against their will. Jesus willingly laid down his life to die on the cross.
[Jhn 10:18 KJV] 18 No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.
4. The Jews were not joyful going to their death. Jesus endured the cross for the joy set before him of the salvation of mankind.
[Heb 12:2 KJV] 2 Looking unto Jesus the author and finisher of [our] faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
5. There was no victorious moment for the death of the Jews. Jesus was victorious over death because he resurrected from the dead.
[Jhn 11:25 KJV] 25 Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live:
Another problem with the view the Jews underwent vicarious suffering during the Holocaust is it is a minority view among Jews. I'll post more about that in a separate post.
