The Council of Nicea (Nicaea) was held in 325 AD in what is now Iznik, Turkey. Roman emperor Constantine invited all Christian bishops to convene, at his expense, to settle some theological conflicts. There are a lot of urban legends about what happened.
One of the most common objections about the Bible is that it was supposedly created by Roman Emperor Constantine at the Council of Nicea in AD 325. Of course, that's not true. It's mythology, not history. So what really happened at the council of Nicea?
