I have been wondering for a while what would change if the Arians managed to become the dominant Christian sect. If at Nicea the word "homoousios" was not used or if Constantius II and his wife were able to have children and ingrain an Arian belief system in him, or if the Goths and Vandels decided to continue in the Arian belief instead of converting to the Trinity. Would there be that big of difference, if the split continued, it would be much stronger in the east, (and Germany) then in the West, and would you see a much earlier scism.
I think the biggest chance would be the lack of "homoousios" in the Council of Nicea since that was the sticking point for most of the opposition, and a much higer rate of conversion for many of the German tribes then in OTL, besides a lack of the centralization of the Catholic Church, dont think it would affect the conversion of pagans to Christianity, it may even hasten it, (since almost every Germanic tribe converted to Arianism first and then Catholism) The Arabs would be more devastating since its power was so much stronger in the east then Catholisim was.
