Some time ago, I read the short book Are We Together? A Protestant Analyzes Catholicism written by the late Reformed preacher R.C. Sproul. It was a good read; I thought that Sproul treated this controversy with a degree of fairness and accuracy that was not present in other books that I have read on this subject. He basically laid the Catechism of the Catholic Church and the Westminster Confession side-by-side as he worked through the major differences. Sure, there were some snarky comments here and there but I overlooked these since it was clear that the book was being targeted...
