This one. My point was to emphasize that the concepts, the mechanisms, are present in both Lutheranism and Roman Catholicism. The fundamental understanding of the soteriological process is essentially shared between our two western traditions (as my Eastern Orthodox priest buddy would say, perhaps even more clearly than with the Orthodox and their understanding of Theosis… but that’s another thread…). Yet the terminology and the approach to the concepts is not.
Luckily, we are blessed with incredible minds like Benedict XVI who can see multiple approaches simultaneously and harmonize what, at first glace, may appear to be contradictory – and not with poo-poo ecumenical speak, but with a firm, solid understanding of both approaches. If only a man like him were pope 500 years ago.
