Agreed. So why do Protestants cling to beliefs that are provably contrary to scripture and have no pedigree before the 12th Century, like Luther's warped concept of grace as a merely extrinsic and forensic concept?
I recommend reading the confession of Patrick of Hibernia. He sounds a lot like Paul of Tarsus than Thomas Aquinas. His command of the NT, Psalms, Torah and Prophets is a testimony for us all.
