Canon 81 No addition to the Thrice-Holy Hymn

Since we have learned that in certain regions, in the Thrice-Holy Hymn, there is proclaimed by way of addition, after "Holy Immortal", the words "Who was crucified for us, have mercy on us"; and this was driven out of that hymn by the holy Fathers of old as foreign to piety, together with the lawless heretic who invented such a phrase; we also, confirming what was formerly piously enacted by our holy Fathers, anathematise those who, after the present definition, still receive such a phrase in churches, or in any other way join it to the Thrice-Holy Hymn. And if the transgressor of what has been decreed is of priestly rank, we command that he be stripped of the priestly dignity; and if a layman or a monk, that he be excommunicated.
