Article by by Mike Riccardi (original source here with helpful comment thread). Questions such as these are answered:

1. Why should I bother myself with learning about metaphysics?
2. Does the incarnation “interrupt” the simplicity of God? And relatedly, does the Son remain incarnate forever?
3. Does a denial of simplicity go hand in hand with holding to a doctrine of the eternal functional subordination of the Son to the Father, that topic that was vigorously debated last summer?
4. What about Scott Oliphint’s notion of “covenantal properties” in God?
5. How does the difference between a classical versus presuppositional view of epistemology bear on this discussion?
