My 2 cents. There are a lot of opinions, but few provable facts.
Emperor Constantine had a real political problem in the province. It was a turning point in history. The Roman's had many "gods". The uprising of the "Christians" and the many factions there of. He needed a consensus to calm the crowds and fighting.
He called together some 20+ Catholic Bishops to put an end to political unrest. The Counsel of Nicaea.
Arius showed up. Arius had largely been dismissed as he preached against the divinity of Jesus and against the Trinity. Not only did they kick him out, they banished him to the north and ordered all of his works to be burned. The entire NT was very specifically collected around the concept of the Trinity - if nothing else to prove Arius very wrong. His works were considered completely dead by 380AD.
Until Charles Russell picked them up somewhere around 1875 and thought they were cool.
The Adventist, and JW/Watchtower descendants are still known as the Arianism. The rejectors of Jesus.
There was such persecution of there ideas that they had to plagiarizer their own version of the Bible to quell questions about their own publishing to their own congregation.
"There are a lot of opinions, but few provable facts." - but everyone knows that the JW/WT has deliberately changed worlds in the Bible to the NWT to conceal the facts.
Cha ching another million books sold by a "publishing company"..... every couple of years.
