"There is just now a fashion for upholding something called 'Nicene' Christianity. But the great creeds of the fourth and fifth centuries were never intended as a complete teaching syllabus, and when used that way they screen out the central theme of the four Gospels: How God Became King (aka The Kingdom of God). Western Christianity has thus lurched between a faith based on incarnation and cross (but without 'kingdom') and a social-gospel 'kingdom'-movement (but without incarnation and cross). How can we put back together what the Gospels were trying to tell us all along?"
From the January Series at Calvin College in 2012.
