Universalism has biblical and historic support. Four of the six theological schools in the first five or six centuries of Christianity were Universalist. Unfortunately, the one school (Carthage or Rome) taught endless punishment of the wicked. They were the ones who gave us our biased Bible.

German theologian- Philip Schaff writes :
"In the first five or six centuries of Christianity there were six theological schools, of which four (Alexandria, Antioch, Caesarea, and Edessa, or Nisibis) were Universalist, one (Ephesus) accepted conditional immortality; one (Carthage or Rome) taught endless punishment of the wicked. Other theological schools are mentioned as founded by Universalists, but their actual doctrine on this subject is not known."
