Whose Epistemology?

Post­mod­ernism, like mod­ernism before it, is built around the Carte­sian idea that all knowl­edge begins with the “I” that exists (cog­ito, ergo sum: I think, there­fore I am — Descartes).  Post­mod­ernism dif­fers from mod­ernism in the sense that the “I” is con­stantly chang­ing (this leads into per­spec­tivism). Pre­mod­ernism, how­ever, holds to the idea (cor­rectly) that knowl­edge starts with God, thus, all human knowl­edge is ‘merely’ a sub­set of God’s knowledge.

To beg the ques­tion, why must Chris­tian­ity adopt post­mod­ernism to sur­vive, if, pre­sup­po­si­tion­ally, the adop­tion being pro­posed is at it’s core, wrong?
