The Council decided that Christ was consubstantial with the Father. This was in the year A.D. 325. We are thus indebted to a wife-murderer for settling the vexed question of the divinity of the Savior. Theodosius called a council at Constantinople in 381, and this council decided that the Holy Ghost proceeded from the Father. Theodosius, the younger, assembled another council at Ephesus to ascertain who the Virgin Mary really was, and it was solemnly decided in the year 431 that she was the Mother of God.
In 451 it was decided by a council held at Chalcedon, called together by the Emperor Marcian, that Christ had two natures -- the human and divine. In 680, in another general council, held at Constantinople, convened by order of Pognatius, it was also declared that Christ had two wills, and in the year 1274 it was decided at the council of Lyons that the Holy Ghost proceeded not only from the Father, but from the Son as well.
Had it not been for these councils, we might have been without a Trinity even to this day. When we take into consideration the fact that a belief in the Trinity is absolutely essential to salvation, how unfortunate it was for the world that this doctrine was not established until the year 1274. Think of the millions that dropped into hell while these questions were being discussed."

And Andres Celsius gave us water freezing at 100 degrees in his own scale!
We moved on from there too...
Interesting comment by Mr. Ingersoll.
All of these "decisions" were not the time that these facts were established. It's just the particular time in history a group proclaimed them to be true.
The fact of the Trinity was established thousands of years ago and became more evident about 2 thousand years ago.
