Did Constantine decide the contents of the Bible at the Council of Nicea in 325 AD?

We speak every so often to people who make the claim that the contents of the Bible were decided or changed by the Emperor Constantine at the Council of Nicea. Here is an article by Dr. James R. White addressing the issue of what really happened at Nicea. I hope it will be instructive to you.

What Really Happened at Nicea? by James R. White

Summary
The Council of Nicea is often misrepresented by cults and other religious movements. The actual concern of the council was clearly and unambiguously the relationship between the Father and the Son. Is Christ a creature, or true God? The council said He was true God. Yet, the opponents of the deity of Christ did not simply give up after the council’s decision. In fact, they almost succeeded in overturning the Nicene affirmation of Christ’s deity. But faithful Christians like Athanasius continued to defend the truth, and in the end, truth triumphed over error.
