He sure likes to throw around the “Heretic” comment, doesn’t he?
Well, from the eastern perspective all westerners are hairyticks, starting with what they call the mother of all heresies, the filioque clause Rome unilaterally added to the Nicene Creed, which was in violation of the two ecumenical councils of Nicea and Chalcedon, by the way.
I am using the word "heretic" in the proper Greek context. It is not derogatory and you are more than welcome to look up the correct meaning. Heresy is that which is not taught by the Church.
