How could a perennialist argument for God be developed?

Roughly, metaphysical perennialism is the thesis that the great religious traditions converge upon a shared set of core metaphysical claims. Without getting into all of the different strands of perennialism available, there has been very little written on how one can reason to God from perennialist truths. This paper sketches out how one could go about reasoning to God from perennial truths. Toward the end of the paper, I raise an important objection to perennialist style arguments and argue that perennialists are not without a response.
