A few comments about this philosophy question:
I believe I agree with squirt…that theism and atheism are too broad to each be considered a philosophy. For instance, some theists could be empiricists in that they believe all that they hold true should be empirically proven, and perhaps the proofs for Jesus’ resurrection and other various miracles is sufficient evidence to warrant a belief in God. Others, I’m sure, just believe in God for no reason at all. Athiests, for instance, might be complete relativists who believe no truth exists at all, while others might be naturalists who believe that some truth exists but only that which can be perceived by the senses.
So I don’t know if that actually has any importance in this discussion, but I thought I’d throw my two cents in on that.
As far as a belief in God goes…couldn’t God be seen as a posited explanation for the universe? For instance, there are the classic Scholastic arguments by cosmology, causality, morality, etc (with some updated variations to them) that indicate that God exists. Now I would imagine that James might reply by saying: “Sure, sure but my point still stands because you don’t know anything about this metaphysical God, and therefore, you’re not really believing in anything.”
But I think the importance of the classic “proofs” for God is their role in the calculation of an antecedent probability that God raised Jesus from the dead on the first Easter Sunday (if you have no clue what I’m talking about here we should talk about this in more detail).
I don’t know how familiar everyone here is familiar with the proofs for the Resurrection but they are very convincing in my opinion. I think they are rendered even more convincing by taking into account the probable existence of this metaphysical God.
If Jesus truly was God made flesh, then he truly could have given the Apostles some knowledge of the true God. Granted, this is nowhere near complete knowledge, but I have nowhere near complete knowledge of anyone on this forum but I do believe (justifiably) that you all actually exist and that my belief is about a real you. What is interesting too is that if Jesus really were God made flesh, then the words that the prophets were told by the Spirit of God must also be true. The prophets also, then, give us real knowledge of what this metaphysical God is like.
And finally, if this metaphysical God Incarnate did establish this Church on Earth, we can also know him through Her.
