I'll be honest: Origen's commentary on Romans has had a huge impact on my decision to become Catholic, but in ways I did not expect. It was actually the soteriological continuity (in a sacramental synergism) between he and Augustine (yes, you'll be fine, just breathe) that has made it tons easier to see, understand, and believe what the bishops taught at the Council of Trent, which is itself a restatement of Thomas Aquinas, applied to those present difficulties. Once I saw that Thomas, though brilliant in any case, was not the product of some corrupt medievalism but instead simply built upon what had always been believed, it was all academic from there. Hey Reformed people: That Paul Helm dude is good; I definitely enjoyed reading that guy's blog. Regent; I should have known.
