There has been a discussion for how Reformed Christians should understand the usefulness and the errors in the philosophy of Thomas Aquinas. I think like every thinker that he is a mixed bag and you will have to weight aspects and arguments. I’ll provide some materials that explain where Christian thought and the thought of Thomas Aquinas differ. They also will discuss where they correspond.
