Was Jesus made divine by vote at the Council of Nicaea…?
Not quite correct. The earliest Christians didn’t think about the nature of Jesus. They were too busy getting ready for his imminent return. When that didn’t happen, they calmed down and had time to think about just what Jesus must have been. In Paul’s earliest letters, he says that Jesus was RAISED from the dead. That’s passive tense. It appears that God “adopted” Jesus as his son after his death and brought him back to life. When Mark wrote his gospel, he clearly depicted the moment when God adopted Jesus, at his baptism by John. Before that point, there was no story. A few years later, Matthew and Luke clarified things still further by depicting Jesus as God at his birth. (The fact that their details didn’t agree was not important.) By the time John got around to his gospel, Jesus was nothing less than co-creator with God the Father. But there were still problems. More stuff was being written and it didn’t all agree. How could Jesus be God AND pray to God? Was he really human at all
