I simply want to point out that there is no reason why Christian universalism should be treated any differently within the Christian community than Calvinism or Arminianism. At least on the surface, there are biblical passages that seem to support all three theological viewpoints about the fate of non-Christians. This is not to say that all interpretations are equal, but it is to say that universalism is in very much the same boat as the other two options: all three positions have some passages that seem to support them, and they all must find ways to interpret difficult passages that seem to support other views….
Christian universalism simply affirms with Calvinists that God can and will do whatever God desires to do, and with the Arminians that God desires to save all people. Put those premises together, and you get the conclusion that God will save all people.
