I for one completely agree with that priest. “Thomism” as written by St. Thomas Aquinas (if it can really be called Thomism at all, since really he was more of a pan-Patristic theologian who used Aristotlean terminology) was actually heavily influenced by Eastern Fathers, perhaps moreso than any other Latin theologian in history.
Later Thomists turned his writings into a systematic thing, and approached questions from a much different angle than St. Thomas himself (he was big on contemplative prayer and meditation, and could be considered a mystic with a knack for utilizing philosophical and scientific terminology to express mystical reality).
That being said, I also think Mardukm’s point has merit. Thomism, and Scholasticism in general, was a big hitter in Eastern Orthodox theology until the Neo-Palamite movement of the past century or so.
Personally I have no problems rectifying to the two theological approaches, and I find them much easier to reconcile than most other Latin approaches and Eastern Orthodoxy (many great Eastern Orthodox theologians felt the same way, which is why the Summa was translated into Greek
after the big breach post-Council of Florence.
Now I should read the article!
Peace and God bless!
