Christians do not believe that there is one God and three Gods. Nor do we believe that God is one person and three persons. That would clearly be contradictory and therefore logically impossible. Rather, the doctrine of the Trinity is that there is one God who eternally exists as three distinct persons. We believe that The Father, The Son, and The Holy Spirit are each individual persons in their own right, but they all share the same divine essence. Saying that "God is one being who consists of three persons" is no more contradictory than saying that "There's one triangle that consists of three corners
