Which words were inflammatory and why? By inflammatory do you mean statements you disagree with? Is it inflammatory to say Aquinas can’t be wrong?
Yes, but some people believe his classical theism is rubbish, has been harmful, and has no place in Christianity. I’m still not sold on his views on war and slavery for example, but hey maybe we can try them again, see how that goes.
Yes. His metaphysics are largely an apologetic for his theology. I have no hesitation junking his metaphysics, and no hesitation junking his theology.
