He does not like this idea of this debate and he wants to help unify the Christians. So in 325, he calls the Council of Nicaea to help resolve this controversy, which gets known as the Arian Controversy, named after Arius of Alexandria. Now, it's worth mentioning, Arius wasn't the first person to make this argument that the Father in some way was more divine than the Son because he begat the Son. He existed before the Son. But this controversy really revolves around Arius because he was especially persuasive about spreading this view of the relationship between the Father and the Son manifested by Jesus. And at the Council of Nicaea, many of the bishops throughout Christendom are in attendance. It's known as the First Ecumenical Conference.
