It was slow, but I remember a major crack occurring watching Stephen Fry being interviewed when he paraphrased David Hume, paraphrasing Epicurus.

If God is unable to prevent evil, then he is not all-powerful. If God is not willing to prevent evil, then he is not all-good

Things start to fall apart from there. All the other Bible stuff can be explained away as being recorded by imperfect beings, but the core notion of a good God worthy of worship ends with the trilemma.
