78 EpisodesProduced by Mark Cain, UCA memberWebsite

The Trinity doctrine is perplexing. Many Christians prefer explicit Scriptures on the one God over catholic creeds. Mark Cain explores living as a lower-case-u unitarian amid a trinitarian majority with insights and stories from unorthodox guests.
