Your source and post gives the impression that Greek Orthodox teaching is compatible with Reformed Theology. It is not. This is not in any way an attempt to trash the five solas and it would be interesting to understand why the doctrine did not gain a foothold in the East.
Are the five solas strongly Western? How does the influence of the writings of Saint Augustine on Calvin prejudice Eastern theologians of the 16th century? When Cyril Lucaris wrote about the “Church” did he mean a visible church?
You did list this as an Eastern Orthodox caucus so I think a discussion of Eastern Orthodox beliefs is not out of place nor is it trashing.
Are you Eastern Orthodox. If not, why is it so hard to follow the rules?
