This is just a quick summary that might be useful regarding the threads about the trinity currently on the board.
In 325 ce, the Nicene council was called by Constantine to settle schisms within the christian church. The argument about the nature of Jesus in relation to God was one of the big problems that needed resolution. At first, Constantine told the 2 main players, Alexander and Arius to sort it out between themselves, as he, Constantine didnt see it as overly important. However, it wasnt settled and was starting to cause political problems for Constantine within his empire.
From the start, there were a lot of people on each side of the debate, some believing Jesus was like God and didnt have a beginning and the other side, believing he was created by God. This wasnt a case of a small, fringe group with a crazy idea, going against the established belief, it had been a debated topic for a long time, over a large part of the Roman Empire.
The eventual outcome of the 300 people at the council is that the consensus agreed with Alexander and the trinity doctine was made the standard to be followed. Anyone that didnt agree to the new belief was threatened with ex-communication and exile, which is what happened to Arius.
The question is, where is God in all this decision making? There is no suggestion that any of the opposing camps were ungodly, or werent living their lives as Christians. This was a purely political decision, voted on by men, under the threat of exile and overseen by the Emperor to maintain control of the state religion. The nature of Jesus was a legitimate question then and it is now, which is why it cant be explained easily as either side has pro's and con's to their argument. And really, who gets to dictate the answer? An Emperor that lived around 2000 years ago and has the power to stop thought and debate to this day?
This next part is pure speculation. Only bits and pieces of the NT have been discovered from after 100 ce. There is nothing from the 1st century and the first complete bible didnt arrive until the early 4th century at best. Thats almost 400 after Jesus died. 400 years is a long time. Perhaps, once the offical doctrines had been adopted from 325 onwards, any surviving early manuscritps were destroyed by the early church to remove as many opposing ideas as possible? This also allows the new testament to be subtly altered to capture the ideas of the newly adopted doctrines. This isnt far-fetched as this is exactly what the JW's do right now, in plain sight.
