He [Antony Flew, then-atheist] took part in cordial debates with theists, which included one in 1985 with philosopher and theologian Dr Gary Habermas on the most important reported deed of all, the proposition that Jesus Christ conquered death itself. This debate was held in Dallas in front of a crowd of three thousand people. It was judged by two panels of experts from leading American universities: one panel comprised five philosophers who were asked to judge the content of the debate, and the other comprised five professional debate judges who were asked to judge the quality of the arguments.
Four of the five on the philosophers panel voted that Habermas had won, i.e. the case he made for the Resurrection was stronger than Flew’s attempts to refute it, and one scored it a draw. The panel of professional debate judges voted three to two to Habermas.
