Is the God of Calvinism a Moral Monster? [Calvinist Caucus]
No. Next question?
Seriously, I can think of a couple ways to go at this. 1)Creator-creature distinction. And, 2)noting that one of the usual examples, the conquest of Caanan, should serve as an illustration of, and warning of, the final judgement. Google on "intrusion ethics".
is a God who only saves some of His children a moral monster?
Note the assumption in the question.
I'll have to look this post, and thread, over in more detail later.
