to Epiphanius Patriark of Constantinople; We preserue in all things the estate of the vnitie of the holy Churches, with the holy Pope of old Rome. And in the lawe ad∣dressed to the Pope; We haue had care to vnite and submitt all the Bishops of the East to the Sea of your Holynesse, 〈◊〉〈◊〉 who are the head of all the holy Churches. This apperes by Menas Patriarke of Constantinople, who said in the Coun∣cell of Constantinople; Wee follow the Sea Apostolicke and obey it, and communi∣cate with those that communicate therewith, and condemne those that it condemnes. This appeares by the forme that saint GREGORIE left vs of the abiura∣tion, that the Bishopes returning from Schisme, to the communion of the Church, made into the handes of the Apostolicke Procurators, which haue these wordes: I Bishop of such a Cittie, hauing discerned the trapp of diuision wherein I was caught, after a longe and mature deliberation, I am returned by Gods grace with my pure and free will, to the vnitie of the Sea Apostolick, and that I may not be esteemed to returne maliciously or sainedly, I vowe and promise vnder paine of falling from myne Order, and vnder obligation of 〈◊〉〈◊〉 to thee, and by thee, to the holy Prince of Apostles, Peter, and to his Vicar the most Blessed GREGORIE, or to his Successors, that by anie perswasion whatsoeuer, or in anie other manner, I will neuer returne to Schisme, from whence by our Redeemers mercy I haue bene deliuered, but that I will alwaies remaine in the vnity of the Ca∣tholique Church, and in the Communion of the Bishop of Rome:
And this finally appeares by the extract of the Councell of 〈◊〉〈◊〉 which is to be read at the end of the latine edition of the Councell of Chalcedon vnder the name of the extract of the Councell of Nicea for the composi∣tion of formed letters made by Atticus Bishop of Constantinople; but some manuscripts of the sixt Councell of Carthage testifie they were sent into the west by the same Atticus, with the other decrees of the Councell of Nicea, when the Asrican Bishops requested them of him. For this extract ordained, that they should take the number of the firste Greeke letters of the names Father, Sonn, and Holy Ghost, the number of the first letter of the Apostle Peters name, and of the author that writt, and of him to whom he writt, and of the bearer of the letter, and of the place from whence it was written, and the day of Paske, and adding them to the number of the indi∣ction which then was currant, they should thereof make a summe, whose cipher should be added to the Epistle, to serue it for a forme and chara∣cter. By meanes whereof when there was noe more occasion to doubt, who was either in communion with the Roman Church or saint Peters sea, or out of it, as the diligence of the Catholicke Emperors, and Kings haue in the West left noe subiect of that doubt this many ages, the necessity of these kind of letters hath ceased. And therefore soe farr off is it, that the vse of the letters formed or cōmunicatory whereof antiquity made vse, was a marke to shew, that the Church was then more manifest then nowe, as contrarywise it was a testimonie, that she was much harder to be discerned then she is at this present. For that which constrained them to vse this meanes, was the multitude, and confusion of heresies which were then in soe great number and soe mingled in aboade, and habitation amidst the Catholicke Church, as there was almost noe Towne, where there was not to bee found, besides the true Church, a dozen Sects, and he∣resies, and the most of them agreeing in forme, and outward worship with the Catholicke Church; Arians, Donatistes, Pelagians Nouatians Macedo∣nians, Appolinaristes, and other such like plagues.
