I found an interesting article written by a Presbyterian Minister who became a Roman Catholic, the article is all about the similarities between Calvinism and Catholicism and how you can basically be a 3-ish point Calvinist while being a Catholic (closer to Calvin than the Methodists are). I really like the article alot, as I find myself leaning strongly Augustinian/Thomistic on views of the fall, predestination, unconditional election, and irresistible grace (even though it got killed at Trent).
Here it is: http://www.cin.org/users/james/files/tulip.htm
It’s nice to be reminded that of all the good doctrines Catholics can hold – even though the Church at large seems to hide quite well or water down quite a bit the doctrines of grace.
