They come up with the Nicaean Creed. A lot of the debate is whether Jesus as son of God should be considered equal to God or as God or a little less as being the son. Maybe if he's a son, maybe there was a time where there wasn't a son and there was just God. But the Nicaean Creed says no, they are one and the same. These two things are equivalent. And then Constantine on his deathbed famously gets baptized and becomes a Christian, the first Christian emperor of this gigantic Roman empire. And so you can imagine, you have more and more followers of Christianity, but now this is, so to speak, prime time.
