Abstract
The Nicene-Constantinopolitan Creed begins with the affirmation “I believe in one God.” There is also the belief that this one God is incorporeal, outside both time and space, and beyond our comprehension. Yet at the same time, this unknowable God has revealed himself to us in many ways. Orthodoxy, like other faiths, struggled to reconcile these two seemingly contradictory beliefs. ‘“I believe”’ explains that what makes Christianity distinct from the other Abrahamic faiths is the belief that the one God exists as a Trinity of persons—the Father, Son, and Holy Spirit. It also describes the concept of theosis (or deification) that is central to Orthodox thinking about the human person and his/her destiny.
