Reformed Scholasticism

Reformed theology is supposed to be grounded in exegetical theology. Only revealed truths merit the status of articles of faith. That includes correct interpretations of revealed truths as well as valid inferences from revealed truths. That's based on the sola scripture principle. 

Even at that level, Reformed interpretations must remain open to exegetical scrutiny. We need to be able to defend our interpretations.

Reformed theology is quite stable. However, it's necessary to distinguish between Reformed theology and philosophical schools of thought that are deployed to expound and defend Reformed theology. 

The problem is when Reformed theology becomes aligned with a particular philosophical paradigm, like Thomism, so that affirming Reformed theology becomes inseparable from affirming the philosophical tradition that sponsors it. 

Thomism should never be elevated to an article of faith. That idolizes philosophy. Philosophical theology must remain subject to rational scrutiny, insofar as philosophical theology relies on natural reason in the first place. 

Philosophical theology ought to be more eclectic and discriminating. Not form an exclusive alliance with any particular philosopher or philosophical school of thought.
