Kosta, I'm pleasantly in awe.
You're making an absolutely beautiful Providentialist argument for God's Election and Preservation of the True Canon of the Holy Scriptures in the Eastern Orthodox Church. (And especially therein, as opposed to the corrupt Vulgate of the Latins, which is why the "textus receptus" Western Reformers tried to get back to the Byzantine Greek texts as best they were able).
Certainly, the "synergistic" participation of the blessed Saints was part of the equation; Athanasius contra mundum, and all the rest. But you do good justice to the Eastern Orthodox appreciation of "The Monarchy of the Father" in asserting the Father's divine superintendance overall in the Election and Preservation of the Scriptures generally, and in the Byzantine Greek textus receptus particularly.
I would only reserve, as a Calvinist -- that I believe that the Father does not exhibit any less particular Election and Preservation in regard to His Saints, than He does in regard to His Scriptures.
If Calvinists and Orthodox can ever get on the same page in that point of discussion, it will be a good time for Reformed and Presbyterian Christians to join the Lutherans and Orthodox in their ecumenical conversations!!
Interesting stuff. Thanks for the Post. :-)
best, OP
