“I dont see the ECFs or those councils appeal to the original languages that often.”
They used Greek, even for the OT (the Septuagint). Even the Jews used Greek then. I’ve been told that some of the Fathers used Aramaic but I’ve never been able to confirm that.
You’re sure of this?
It's always been my understanding the the Greek Orthodox used the Old Latin Bible (not Jerome's Vulgate) and the church still has some copies of that translation...I also understand that the Old Latin matches the KJV and not the Septuagint...
