Christian theology is a dialogue through the ages among mostly friends and sometimes enemies. However, the best and longest lasting theological perspectives were among friends. Would we have the works of Irenaeus, and dare I say the canon, if not for his friend and mentor Polycarp? How would we understand the Trinity apart from the friendship of Gregory Nazianzus and Basil of Caesarea? Of course, there are great antagonistic relationships in Church history as well. Augustine and Pelagius come to mind. However, Augustine was not at his best arguing with Pelagius, and perhaps he was at his worst. Thus, in my opinion, it is a fact of history that theology is best suited for friendly and critical discussion.
