I recently engaged in a debate with Jason Pratt who heavily emphasized that he is a Trinitarian, and who considers himself an "Evangelical Universalist." I argued from five passages that judgment is coming, that it will be eternal, and that some people will experience it. Chris Date moderated the debate and has hosted the debate in the form of three podcasts:
Resolved: Some people will not be saved from their sins according to the following
passages and their contexts: 2 Thess. 1:9, Matt. 25:41/46, Matt. 18:8,
Romans 9:22 and Jude 1:6.
Chris Date's own podcast pages can be found here (first, second, third), which also contains links to the "raw" audio and other information.
