This portion of your post evidences a severe misunderstanding of the nature of the council.The concept of the trinity comes from the Council of Nicea and other councils that God is three persons in one. This council was called in 325 AD by Constantine, a pagan leader of Rome. He wanted to make Christianity a state religion and was desirous that the christians agreed on some basic concepts including the nature God. It is this disagreement on the nature of God that we are referred to as a cult.
Trinitarian Christianity was already present - it was the minority of writers before the council, but was extant. (There are hints of it even in the Gospels.) After the council, the majority of the Council Fathers, much to the surprise of several groups, affirmed the Trinity, the full participation in divinity of Christ
This is the core teaching of the Nicene Council:
We believe in one God, the Father Almighty, Maker of all things visible and invisible.
And in one Lord Jesus Christ, the Son of God, begotten of the Father the only-begotten; that is, of the essence of the Father, God of God, Light of Light, very God of very God, begotten, not made, being of one substance with the Father;
By whom all things were made both in heaven and on earth
Who for us men, and for our salvation, came down and was incarnate and was made man;
He suffered, and the third day he rose again, ascended into heaven;
From thence he shall come to judge the quick and the dead.
And in the Holy Ghost.
But those who say: ‘There was a time when he was not;’ and ‘He was not before he was made;’ and ‘He was made out of nothing,’ or ‘He is of another substance’ or ‘essence,’ or ‘The Son of God is created,’ or ‘changeable,’ or ‘alterable’—they are condemned by the holy catholic and apostolic Church.
An earlier council following the council at Jerusalem in about AD 50, would have been unlikely - persecution of the Christians had started in 58 or so, and ended only 12 years before Nicea, and it would take a decade or longer for many to not believe it a mere trick of the Roman state to gather and execute the leadership of the church.
The Definition of “Christian” was passed at Nicea, as well - and Mormons don’t fit it. The Empire adopted it… but the counil devised and passed it.
