"The iconoclasts were not Orthodox and were defeated."
Irrelevant. They were baptized Orthodox Christians who held responsible and important positions in the Orthodox Church when they developed their heresy. Nothing I said goes contray to that and you can't change those facts either.
"The Orthodox celebrate their defeat on a designated feast day."
Yes, I know. Been there, done that.
"By the way - the Orthodox Church also considers itself to be Roman. 'Orthodoxy and Romiosini'."
It can consider itself Martian. The Turks think the EC is Roman after all!!! Is it Roman? No. It's not even really Constantinople anymore either.
"The Franks did change church teaching - see Filioque."
Uh, you do realize that 1) filioque didn't start with the Franks right? I mean, you did know that it was discussed in Toledo in 447 didn't you? You do realize that the Franks were not EVEN BAPTIZED CHRISTIANS AT THAT POINT RIGHT? 2) it isn't a change in doctrine (even some EOs admit this).
A change in doctrine would be like when some EOs renounced the Assumption of Mary for no other reason than the fact that the Catholic Church defined it as doctrine in 1950!!! How disgusting! That's the sort of lunacy that follows in the wake of anti-Catholic hatred.
So were the Catholic Germans who sided with Father Martin Luther.
