In this episode of 'Passages,' Joshua and Caleb are joined by Dr. Michael Horton and Dr. Fred Sanders to discuss some of the backstories behind the article in the Nicene Creed that we says the One God is the "maker of heaven and earth, of all things visible and invisible." Listen in to hear commentary on Gnosticism, Marcionism, and Tertullian.
