The Faith of the Three Hundred and Eighteen Fathers assembled at Nice in Bithynia shall not be set aside, but shall remain firm. And every heresy shall be anathematized, particularly that of the Eunomians or [Anomoeans, the Arians or] Eudoxians, and that of the Semi-Arians or Pneumatomachi, and that of the Sabellians, and that of the Marcellians, and that of the Photinians, and that of the Apollinarians
The bishops are not to go beyond their dioceses to churches lying outside of their bounds, nor bring confusion on the churches; but let the Bishop of Alexandria, according to the canons, alone administer the affairs of Egypt; and let the bishops of the East manage the East alone, the privileges of the Church in Antioch, which are mentioned in the canons of Nice, being preserved; and let the bishops of the Asian Diocese administer the Asian affairs only; and the Pontic bishops only Pontic matters; and the Thracian bishops only Thracian affairs. And let not bishops go beyond their dioceses for ordination or any other ecclesiastical ministrations, unless they be invited. And the aforesaid canon concerning dioceses being observed, it is evident that the synod of every province will administer the affairs of that particular province as was decreed at Nice. But the Churches of God in heathen nations must be governed according to the custom which has prevailed from the times of the Fathers
The Bishop of Constantinople, however, shall have the prerogative of honor after the Bishop of Rome; because Constantinople is New Rome.
Concerning Maximus the Cynic and the disorder which has happened in Constantinople on his account, it is decreed that Maximus never was and is not now a Bishop; that those who have been ordained by him are in no order whatever of the clergy; since all which has been done concerning him or by him, is declared to be invalid.
(Probably adopted at a Council held in Constantinople the next year, 382. Vide. Introduction on the number of the Canons.)
As concerning the tome of the Westerners [Bishops], we have accepted also those in Antioch who confess a single divinity of the Father and of Son and of Holy Spirit.
(Probably adopted at a Council held in Constantinople the next year, 382. Vide Introduction on the number of Canons.)
Forasmuch as many wishing to confuse and overturn ecclesiastical order, do contentiously and slanderously fabricate charges against the orthodox bishops who have the administration of the Churches, intending nothing else than to stain the reputation of the priests and raise up disturbances amongst the peaceful laity; therefore it seemed right to the Holy Synod of Bishops assembled together in Constantinople, not to admit accusers without examination; and neither to allow all persons whatsoever to bring accusations against the rulers of the Church, nor, on the other hand, to exclude all. If then, any one shall bring a private complaint against the Bishop, that is, one relating to his own affairs, as, for example, that he has been defrauded, or otherwise unjustly treated by him, in such accusations no examination shall be made, either of the person or of the religion of the accuser; for it is by all means necessary that the conscience of the Bishop should be free, and that he who says he has been wronged should meet with righteous judgment, of whatever religion he may be. But if the charge alleged against the Bishop be that of some ecclesiastical offence, then it is necessary to examine carefully the persons of the accusers, so that, in the first place, heretics may not be suffered to bring accusations touching ecclesiastical matters against orthodox bishops. And by heretics we mean both those who were aforetime cast out and those whom we ourselves have since anathematized, and also those professing to hold the true faith who have separated from our canonical bishops, and set up conventicles in opposition [to them]. Moreover, if there be any who have been condemned for faults and cast out of the Church, or excommunicated, whether of the clergy or the laity, neither shall it be lawful for these to bring an accusation against the bishop, until they have cleared away the charge against themselves. In like manner, persons who are under previous accusations are not to be permitted to bring charges against a bishop or any other clergyman, until they shall have proved their own innocence of the accusation brought against them. But if any, being neither heretics, nor excommunicate, nor condemned, nor under previous accusation for alleged faults, should declare that they have any ecclesiastical charge against the bishop, the Holy Synod bids them first lay their charges before all the Bishops of the Province, and before them prove the accusations, whatsoever they may be, which they have brought against the bishop. And if the comprovincials should be unable rightly to settle the charges brought against the bishop, then the parties must betake themselves to a greater synod of the bishops of that diocese called together for this purpose; and they shall not produce their allegations before they have promised in writing to undergo an equal penalty to be exacted from themselves, if, in the course of the examination, they shall be proved to have slandered the accused bishop. And if anyone, despising what has been decreed concerning these things, shall presume to annoy the ears of the Emperor, or the courts of temporal judges, or, to the dishonor of all the Bishops of his Province, shall trouble an Ecumenical Synod, such an one shall by no means be admitted as an accuser; forasmuch as he has east contempt upon the Canons, and brought reproach upon the order of the Church.
Those who from heresy turn to orthodoxy, and to the portion of those who are being saved, we receive according to the following method and custom: Arians, and Macedonians, and Sabbatians, and Novatians, who call themselves Cathari or Aristori, and Quartodecimans or Tetradites, and Apollinarians, we receive, upon their giving a written renunciation [of their errors] and anathematize every heresy which is not in accordance with the Holy, Catholic, and Apostolic Church of God. Thereupon, they are first sealed or anointed with the holy oil upon the forehead, eyes, nostrils, mouth, and ears; and when we seal them, we say, "The Seal of the gift of the Holy Ghost." But Eunomians, who are baptized with only one immersion, and Montanists, who are here called Phrygians, and Sabellians, who teach the identity of Father and Son, and do sundry other mischievous things, and [the partisans of] all other heresies-for there are many such here, particularly among those who come from the country of the Galatians:-all these, when they desire to turn to orthodoxy, we receive as heathen. On the first day we make them Christians; on the second, catechumens; on the third, we exorcise them by breathing thrice in their face and ears; and thus we instruct them and oblige them to spend some time in the Church, and to hear the Scriptures; and then we baptize them.
