FIRST COUNCIL OF NICAEA

The first Council of Nicaea was when the church officially discarded their Hebraic Roots and began to embrace paganism.

The First Council of Nicaea was a council of Christian bishops convened in Nicaea in Bithynia (present-day İznik in Turkey) by the Roman Emperor Constantine I in AD 325. This first ecumenical council was the first effort to attain consensus in the church through an assembly representing all of Christendom.

Its main accomplishments were settlement of the Christological issue of the relationship of Jesus to God the Father, the construction of the first part of the Nicene Creed, settling the calculation of the date of Easter, and promulgation of early canon law.

EasterAnother result of the council was an agreement on when to celebrate Easter, the most important feast of the ecclesiastical calendar, decreed in an epistle to the Church of Alexandria in which is simply stated:

We also send you the good news of the settlement concerning the holy pasch, namely that in answer to your prayers this question also has been resolved. All the brethren in the East who have hitherto followed the Jewish practice will henceforth observe the custom of the Romans and of yourselves and of all of us who from ancient times have kept Easter together with you.
The first Sunday after the 1^st full moon after the spring equinox, not before March 22^nd."At the council we also considered the issue of our holiest day, Easter, and it was determined by common consent that everyone, everywhere should celebrate it on one and the same day. For what can be more appropriate, or what more solemn, than that this feast from which we have received the hope of immortality, should be kept by all without variation, using the same order and a clear arrangement? And in the first place, it seemed very unworthy for us to keep this most sacred feast following the custom of the Jews, a people who have soiled their hands in a most terrible outrage, and have thus polluted their souls, and are now deservedly blind. Since we have cast aside their way of calculating the date of the festival, we can ensure that future generations can celebrate this observance at the more accurate time which we have kept from the first day of the passion until the present time...." — Emperor Constantine, following the Council of NicaeaAs early as Pope Sixtus I, some Christians had set Easter to a Sunday in the lunar month of Nisan. To determine which lunar month was to be designated as Nisan, Christians relied on the Jewish community. By the later 3rd century some Christians began to express dissatisfaction with what they took to be the disorderly state of the Jewish calendar. They argued that contemporary Jews were identifying the wrong lunar month as the month of Nisan, choosing a month whose 14th day fell before the spring equinox. Christians, these thinkers argued, should abandon the custom of relying on Jewish informants and instead do their own computations to determine which month should be styled Nisan, setting Easter within this independently computed, Christian Nisan, which would always locate the festival after the equinox. They justified this break with tradition by arguing that it was in fact the contemporary Jewish calendar that had broken with tradition by ignoring the equinox, and that in former times the 14th of Nisan had never preceded the equinox. Others felt that the customary practice of reliance on the Jewish calendar should continue, even if the Jewish computations were in error from a Christian point of view. Constantine:"Resplendent in purple and gold, Constantine made a ceremonial entrance at the opening of the council, probably in early June, but respectfully seated the bishops ahead of himself." As Eusebius described, Constantine "himself proceeded through the midst of the assembly, like some heavenly messenger of God, clothed in raiment which glittered as it were with rays of light, reflecting the glowing radiance of a purple robe, and adorned with the brilliant splendor of gold and precious stones." He was present as an observer, and did not vote. Constantine organized the Council along the lines of the Roman Senate. Hosius of Cordoba may have presided over its deliberations; he was probably one of the Papal legates. Eusebius of Nicomedia probably gave the welcoming address.
