Paleo-orthodoxy (from Ancient Greek παλαιός "ancient" and Koine Greek ὀρθοδοξία "correct belief") is a Protestant Christian theological movement in the United States which emerged in the late 20th and early 21st centuries and which focuses on the consensual understanding of the faith among the ecumenical councils and Church Fathers. While it understands this consensus of the Church Fathers as orthodoxy proper, it calls itself paleo-orthodoxy to distinguish itself from neo-orthodoxy, a movement that was influential among Protestant churches in the mid-20th century.
