There are corroborating stories of this in Greek that can be found at the NFTU site. It is not surprising that things have escalated as Constantinople has made it clear that the Crete event is not to be spoken badly of and Fr. Theodoros has made it clear that ecumenism in general and Crete in particular are invitations to ruin. I've posted many of his videos before (visible here) if you have interest in many of the salient points he has made in the past.
(NFTU) - This past First Sunday in Lent, the Sunday of Orthodoxy, was marked by the prominent New Calendar priest, Protopresbyter Theodore Zisis, becoming a non-commemorator. The announcement was met with marked applause and cheers from the congregation with the announcement. The former Bishop of Fr. Theodore Zisis,Archbishop Antimos of Thessalonika, gave instruction that Fr. Theodore Zisis was no longer to express any criticisms of the Pseudo-Synod of Crete, nor express any anti-modernist and anti-ecumenist thought or face consequences. Fr. Theodore reacted by ceasing commemoration.
This is the implementation of the order given by the Ecumenical Patriarchate that all opponents of ecumenism and modernism must be silenced, or face deposition and excommunication; in fact, Fr. Theodore was named, among others, in particular, for silencing, or face deposition. Some clergy have even left Greece over the hostile attitude being propagated against any vocal anti-modernist and anti-ecumenist State Church clergy (especially in Thessalonika).
Fr. Theodore Zisis had previously beena prominent supporter of the Ecumenical Patriarchate’s ecumenical and modernist ventures, however, beginning in the 1980s he more and more turned against them as contrary to Orthodoxy. This latest move represents the first prominent move among the conservative clergy of the State Church of Greece in opposing measures being taken to completely suppress anti-modernist and anti-ecumenist thought among State Church clergy once and for all. In Romania, the situation has become even more severe, since the official position of the Romanian Patriarchate is that the Pseudo-Synod of Crete is the official position, and opponents will face suspension and deposition.
