Of course, this is a better way to put it, and what I should have gone for in the first place. Thanks, Cavaradossi.
On the other hand, I do not think it is wrong to call particular saints even of the first millennium “Orthodox” or even “Orthodox Catholic”, as the whole point of sticking to such saints – at least my whole point of doing so in the context of the post in which I used them as examples – is to show that these saints held to the faith that was once in common between both East and West, and therefore much liturgical patrimony thought of as “Western” by Western Christians (i.e., as evidence that the Latin Church is so much better or substantial on a world level than the Eastern, in the mind of the person I was writing to) is not in fact rooted in the West at all. St. Athanasius the Apostolic, whether you consider him an exclusively “Catholic” or “Orthodox” saint or not, was certainly not a Westerner. He was not a Latin. Ditto St. Pachomius. Of course, there is nothing wrong with being a Latin, but again, in context, I think this a distinction that should be made. If the Eastern church is so inconsequential, how come so much of the supposedly superior Western church’s practice and theology is based on what they received from the East? They’ve just largely forgotten that that’s actually what it is, is all.
