CANON XV
The rules laid down with reference to Priests and Bishops and Metropolitans are still more applicable to Patriarchs. So that in case any Priest or Bishop or Metropolitan dares to se-cede or apostatize from the communion of his own Patriarch and fails to mention the latter’s name, in accordance with custom duly fixed and ordained, in the divine Mystagogy, but, before a synodal verdict has been pronounced and has passed judgment against him, creates a schism, the holy Synod has decreed that this person shall be held an alien to every priestly function if only he be convicted of having committed this transgression of the law. Accordingly, these rules have been sealed and ordained as respecting those persons who under the pretext of charges against their own presidents stand aloof and create a schism and disrupt the union of the Church.
But, as for those persons, on the other hand, who, on account of some heresy condemned by holy Synods or Fathers, withdrawing themselves from communion with their president who, that is to say, is preaching the heresy publicly and teaching it bareheaded in church, such persons not only are not subject to any canonical penalty on account of their having walled themselves off from any and all communion with the one called a Bishop, before any synodal verdict has been rendered, but also, on the contrary, they shall be deemed worthy to enjoy the honor which befits them among Orthodox Christians. For they have defied not Bishops, but pseudo-bishops and pseudo-teachers; and they have not sundered the union of the Church with any schism but, on the contrary, have been sedu-lous to rescue the Church from schisms and divisions.
