On the Sunday of Orthodoxy, Greek priest Archpriest Theodore Zisis announced that he was ceasing commemoration of his ruling bishop, Metropolitan Anthimos of Thessaloniki, believing that his support of last year’s Pan-Orthodox Council on Crete, which acknowledged the term “church” for other Christian confessions, constitutes a fall into the heresy of ecumenism, which denies that the Orthodox Church is the one, true Church. The next day the metropolitan suspended Fr. Theodore from his priestly duties, reports AgionOros.ru.
Fr. Theodore explained his decision by appealing to Canon 15 of the First-Second Council held in Constantinople in 861, presided over by St. Photios the Great. This canon states that if a bishop clearly preaches a heresy previously condemned by either a council or the holy fathers, then priests are allowed to cease commemorating him in the Liturgy, and are to face no canonical penalties.

The EP has asked Greek Orthodox hierarchs to defrock all priests who protest the recent "Pan-Orthodox Council on Crete". This problematic council raised several issues which are heretical, the worst is its bareheaded promotion of ecumenism. Furthermore, it did not have enough representatives to qualify it as a "Pan-Orthodox Council" as many prelates and delegates refused to participate.
