Prager stated that, "God hates divorce", as if it were from Torah, which I don't think it is.
Torah however, does specifically endorse marriage - and "monogamous" marriage, by which I believe that many of those contemporaneous with Moses and after were in error by polygamy.....
But I diverge.
That God does specifically endorse marriage, would seem to suggest His unhappiness at marriage breaking apart. Though if it should, were that it were done, with the best interests of all parties - and particularly young children - at heart.
To answer the rabbinical Jesus' paraphrase, being a sinner I couldn't cast the first stone.
Thus I must take Prager at least at his initial word.
God's grace on one who's philosophy has likwise added so much to my own.
I think Jewish law considers divorce a tragedy, but not necessarily a disaster and not necessarily immoral.
