The practice had been followed by Polycarp, who was a disciple of John the Apostle and bishop of Smyrna (c. 69 – c. 155) - one of the seven churches of Asia, and by Melito of Sardis (d. c.
"[26] Sozomen also wrote: As the bishops of the West did not deem it necessary to dishonor the tradition believed to be handed down to them by Peter and by Paul, and as, on the other hand, the Asiatic bishops persisted in following the rules laid down by John the evangelist, they unanimously agreed to continue in the observance of the festival according to their respective customs, without separation from communion with each other.
They faithfully and justly assumed, that those who accorded in the essentials of worship ought not to separate from one another on account of customs.A modern source says that the discussion between Polycarp and Anicetus in Rome took place within the framework of a synod.
[29] According to Eusebius, in the last decade of the 2nd century a number of synods were convened to deal with the controversy, ruling unanimously that the celebration of Easter should be observed and be exclusively on Sunday.
[9] The council in Rome, presided over by its bishop Victor, took place in 193 and sent a letter about the matter to Polycrates of Ephesus and the churches of the Roman province of Asia.
He fittingly admonishes Victor that he should not cut off whole churches of God which observed the tradition of an ancient custom.In the short following chapter of the account by Eusebius, a chapter headed "How All came to an Agreement respecting the Passover", he recounts that the Palestinian bishops Narcissus and Theophilus, together with the bishops of Tyre and Ptolemais, wrote a lengthy review of the tradition of Sunday celebration of Easter which believed "had come to them in succession from the apostles", and concluded by saying: Endeavor to send copies of our epistle to every church, that we may not furnish occasion to those who easily deceive their souls.
[30] As shown, for instance, by the Sardica paschal table, it was quite common at that time that the Jewish calendrical year started before and after the equinox according to Exodus 12:2 and Deuteronomy 16:1.
In a letter to the bishops who had not been present, Emperor Constantine I said that it had been decided to adopt a uniform date, rejecting the custom of the Jews, who had crucified Jesus and whose practice often meant that two passovers were celebrated in the same solar year: (Even though there is a commandment to keep a second passover in Numbers 9:10-12 if found unclean to keep the first) It was resolved by the united judgment of all present, that this feast ought to be kept by all and in every place on one and the same day.
For what can be more becoming or honorable to us than that this feast, from which we date our hopes of immortality, should be observed unfailingly by all alike, according to one ascertained order and arrangement?
And first of all, it appeared an unworthy thing that in the celebration of this most holy feast we should follow the practice of the Jews, who have impiously defiled their hands with enormous sin, and are, therefore, deservedly afflicted with blindness of soul.
For we have it in our power, if we abandon their custom, to prolong the due observance of this ordinance to future ages, by a truer order, which we have preserved from the very day of the passion until the present time.
Beloved brethren, let us with one consent adopt this course, and withdraw ourselves from all participation in their baseness... being altogether ignorant of the true adjustment of this question, they sometimes celebrate Pascha (Passover) twice in the same year.
It is, then, plainly the will of Divine Providence (as I suppose you all clearly see), that this usage should receive fitting correction, and be reduced to one uniform rule.It is not known how long the Nisan 14 practice lasted.
Wilfrid, the 7th-century bishop of York in Northumbria, styled his opponents in the Paschal/Easter controversy of his day "quartodecimans",[35] though they celebrated Pascha (Easter) on Sunday.
Many scholars of the 19th and 20th centuries thought that the dispute over Pascha (Easter) that was discussed at Nicaea was between the Nisan 14 practice and Sunday observance.
[37] A new translation, published in 1999, of Eusebius' Life of Constantine suggests that this view is no longer widely accepted;[38] its view is that the dispute at Nicaea was between two schools of Sunday observance: those who followed the traditional practice of relying on Jewish informants to determine the lunar month of the Nisan in which Passover would fall, and those who wished to set it using Christian computations using the spring equinox on the solar calendar.
Laurent Cleenewerck suggests that the East-West schism could even be argued to have started with Victor's attempt to excommunicate the Asian churches.
