Jay Dyer (Eastern Orthodox) had a debate with Shabir Ally (Muslim):
Overall, I believe Dyer won the debate (scoring the debate, it would be 7-3 in his favour). While as a Latter-day Saint, I would disagree with Dyer on issues relating to Trinitarianism, but not as many as those who hold to the Latin formulation thereof (e.g., Dyer believes that the person of the Father alone is autotheos; rejects the filioque).
