1. The most misunderstood form of Christianity.
2. Used as slang by Fundamentalists towards anyone who includes all people into salvation, and not just their small cult.
3. The original belief from Jesus time till the 500's when the Church became imperialized by Rome. Most Christians in the East and the West believed this, such as Pantaneus, Clement of Alexandria, Origen, St. Gregory of Nyssa, St. Macrina the Younger, Theodore Montepusa, Diodore of Tarsus, and other such figures. It is also believed that St. John Crystostom, St. Ambrose, St. Basil and St. Gregory Nazanieth. Both Augustine and Basil admitt that most Christians believed in Universal Salvation. The belief was deemed heretical because the emperor Justinian demanded a council to condemn the belief as a heresy in the 500's.
4. They believe that by Jesus death and resurrection, that all will eventually come to salvation. They study the bible in its original context and understand the original greek words in their original use, not the church defined use. Contrary to popular belief, Universalism does not in any way give one a free pass to sin, or underestimate Jesus work on the cross. They still believe in punishment, but not that it is endless and is for corrective purposes. In fact, Universalism is the only form of Christianity that teaches both an all powerful and all loving God who will get rid of sin once and for all, and died not for a few, but insured everyone salvation.
Christian Universalism is the most loving form of Christianity, because they act like the real Jesus, not this angry Jesus the traditionalist teach.
