The First Council of Nicaea (/naɪ’si:ə/; Greek: Νίκαια /’ni:kaɪja/) 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.

The council dealt with the matters of writing Roman constitutional decrees that were designed to control and govern the Christian Church.

Its main accomplishments were settlement of the Trinitarian issue of the nature of The Son and his relationship to God the Father, the construction of the first part of the Creed of Nicaea, settling the calculation of the date of Easter found in the Easter table was written specific details, so that it may counterfeit the Jewish Passover. 

The council of Nicaea was responsible for the promulgation or the putting into force of the early canon law. The council also initiated the Ecumenical council.

And thus; the Roman laws of Edom which were hostile and Antisemite against the Jewish nation were used to govern and control the Christian church.
