Earlier this month on Speaking of Faith, Krista Tippet played an interview with Jaroslov Pelikan on the history and importance of creeds in religious communities. Pelikan, who recently died, was a History Professor at Yale and a renown writer and scholar on the history of creeds and religion. The interview is incredibly interesting as Pelikan talks about how creeds are markers of identity and faith and how creeds such as the Nicene Creed or the Maasi Creed were developed.
