The author is himself an Orthodox layman. It's concepts like the Orthodox conception of theology that usually take a long time for converts (which I would guess the author is, by his name at least) to integrate in to the rest of their thinking. Something I'm just beginning to work out myself. Still a wonderful article.
On another note, the current issue of Touchstone has a wonderful article on St. Benedict. Considering that he lived 500 years before the Catholic/Orthodox schism, I would think he should be honored as an Orthodox saint as well - and that Orthodox would benefit from studying his writings. It's a shame that even in the West most Orthodox - myself included - are not exposed more to pre-Schism Western saints.
St John Maximovitch of Shanghai and San Francisco who spent some time in France, was very interested in such. He passed that down to Father Seraphim Rose, of blessed memory, and there are a few collections for the Orthodox yet available.
