III. And asks for another Synod to be summoned.
And now that this confession is being godlessly impugned by some few men, all the churches of our parts and all the priests implore your clemency with tears in accordance with the request which Flavian makes in his appeal, to command the assembling together of a special Synod in Italy, in order that all opposition may be expelled or pacified, and that there may be no deviation from or ambiguity in the Faith: and to it should also come the bishops of all the Eastern provinces, that, if any have wandered out of the way of Truth, they may be recalled to their allegiance by wholesome remedies, and they who are under a more grievous charge may either be reduced to submission by counsel or cut off from the one Church.
So that we are bound to preserve both what the Nicene canon enjoins and what the definitions of the bishops of the whole world enjoin according to the custom of the Catholic Church, and also (to maintain) the freedom of our fathers' Faith, on which your tranquillity rests. For we pray that when those who harm the Church are driven out, and your provinces enjoy the possession of justice, and vengeance has been executed on these heretics your royal power also may be defended by Christ's right hand.
