You mention C. S. Lewis attempting to explain the Trinity. I heard another “explanation” in Bill Maher’s Religulous, in that the Father, Son and Holy Ghost are three aspects of the same thing, much like ice, water and steam are three aspects of H20. Elegant, but nonetheless nonsense.

I find myself constantly at odds with believers of many stripes, and this is a puzzle. I’m of average education and intellect, so how come my own beliefs about the nature of the universe are so contrary to the majority’s? It’s this puzzle that keeps me reading the writings of rational authors. But to read what theologians write, to hear what they say, is to be party to a mode of thinking so alien it defies comprehension. Do they really believe this stuff? I’ll grant that many people give little thought to their beliefs – they just believe what they’ve always believed, but theology is studied at learned institutions, with the result that we have theologians spouting palpable absurdities that no ordinary believer would even understand.

I do however sympathise with your view, as you are no doubt aware.

CS Lewis’s defense is yet another version of the three-parts defense, and an erroneous defense, since a cube has six sides, not three. Or does he use some special accounting, like counting two opposite-side faces as one face?
