This is, entirely unironically, the central tenant of the Catholic teaching on the subject.
It really does just boil down to “You can’t adjudicate the morality of the Divine.” And, for the most part, its a line of reasoning that hierarchical social structures condition us to accept. God is just the CEO of the Universe. If you accept that your boss at the toxic waste and murder machines factory is Beyond Good and Evil, believing it about God is downright trivial.
I mean, dealing with the Problem of Evil (or Suffering or however you want to describe it) isn’t unique to Christianity. It certainly isn’t one that’s gone unanswered. Hell, a cornerstone of the orthodoxy is that the Original Sin of defiance of God’s Will is at the root of all evil.
I think there’s a superficial knee-jerk response to these beliefs that boil down to “No, that sounds like some made up bullshit”. But you can dig deeper and talk about the fundamental impulses toward pride and gluttony and conclude there’s a kernel of truth over the religious pastiche.
God is, at the end of the day, an unproveable/unrefutable hypothesis. But the immediate causes of human suffering are knowable, tangible, and preventable. Whether you’re blaming a god or snubbing one, if you’re doing so on the grounds that nobody stopped one human from abusing or neglecting another it would seem like your accusation is misplaced.
Human suffering doesn’t just come from human actions.
It also comes from natural causes, genetic defects, disasters, disease and parasites
I tell this story a lot but as an escaped Xtian the thing that marks the moment I was fully off board with the church was hearing those magic words ‘God works in mysterious ways’. I had heard it so many times because of course they say it all the freaking time but that was the time it really clicked for me that I won’t be getting any real answers and can stop pretending.
