Well, yeah, that's pretty much what I said, isn't it?Not really. The Christian would separate their individual morality and what they perceived as God's morality.
Skeptical theism and utilitarianism are similar in that it they both take into account other criteria than just a prima facie glance in order to determine the morality of an action. A utilitarian could just justify drowning babies and owning slaves so long as those situation justified some moral end.
We all, for the most part, share a human morality that we, individuals, hold collectively to be true
We all, atheist and Christian alike, recognize when God is in violation of our said standard of right and wrong
It's just that Christians insist, for some bizarre reason, that He is not subject to our standard - that He is separate, as you say
Me, I categorize this phenomena of making excuses for God as a suppression of the individual's own better judgment
Alright, so a utilitarian might be able to justify drowning babies IF AND WHEN there is no other way to remove babies from a wicked world and deliver them to Heaven
However, there is NO moral justification for God to drown babies because He CAN remove them from a wicked world and deliver them to Heaven WITHOUT inflicting the harm of drowning upon them!
