We govern ourselves and thumb our noses at Rome when we think it exceeds its bounds.
Rome says there are 21 Ecumenical Councils, but our Church only accepts 7. Rome’s not about to do anything about it because it doesn’t want to antagonize the Orthodox.
Our Holy Synod proclaimed its union with Orthodoxy in the 1990s, but the Orthodox said “No thanks.” And Rome said unity with the Orthodox on a corporate level must come first.
