"I appeal to you, brothers, by the name of our Lord Jesus Christ, that all of you agree, and that there be no divisions among you, but that you be united in the same mind and the same judgment."
(1 Corinthians 1:10)
2025 is a significant anniversary year, celebrating 1700 years since the eccumenical Council of Nicaea first gathered. Christian identity and theology has been fundamentally shaped by the Council of Nicaea.
The year 325 is accepted without hesitation as that of the First Council of Nicaea. The council likely met on or around the 20 May. Later on the 14 June, after the Roman Emperor's arrival, the sessions properly began, with the 'symbol' being formulated on 19 June, after which various other matters were dealt with, and the sessions came to an end 25 August.
The formulation of the symbol of the First Ecumenical Council, of which the following is a literal translation:
We believe in one God the Father Almighty,
Maker of all things visible and invisible;
and in one Lord Jesus Christ,
the only begotten of the Father,
that is, of the substance [ek tes ousias] of the Father,
God of God, light of light,
true God of true God, begotten not made,
of the same substance with the Father [homoousion to patri],
through whom all things were made both in heaven and on earth;
who for us men and our salvation descended,
was incarnate, and was made man,
suffered and rose again the third day,
ascended into heaven and cometh to judge the living and the dead.
And in the Holy Ghost.
Those who say: There was a time when He was not,
and He was not before He was begotten;
and that He was made out of nothing (ex ouk onton);
or who maintain that He is of another hypostasis or another substance [than the Father],
or that the Son of God is created, or mutable, or subject to change,
the Catholic Church anathematizes.
