CS Lewis on Trinity

Some people want a God who is simpler than His creation. But that isn’t the God of the Bible. The Trinity is a concept we can’t truly understand, but can only get a faint idea of. C.S. Lewis summed it up well in Mere Christianity when he said:

“On the human level one person is one being, and any two persons are two separate beings – just as, in two dimensions (say on a flat sheet of paper) one square is one figure, and any two squares are two separate figures.

On the Divine level you still find personalities; but up there you find them combined in new ways which we who do not live on that level, cannot imagine. In God’s dimension, so to speak, you find a being who is three Persons while remaining one Being, just as a cube is six squares while remaining one cube.

Of course, we cannot fully conceive a Being like that: just as, if we were so made that we perceived only two dimensions in space we could never properly imagine a cube. But we can get a sort of faint notion of it. And when we do, we are then, for the first time in our lives, getting some positive idea, however faint of something super-personal – something more than a person.”
