The Holy Trinity

One God in three coequal, coeternal persons: Father, Son, and Holy Spirit

The doctrine of the Holy Trinity confesses that God is one essence, or ousia, in three coequal and coeternal persons, the Father, the Son, and the Holy Spirit. Early terms appear in Theophilus and Tertullian, and the faith was confessed at the Council of Constantinople in 381. It is affirmed across all the major Christian communions, though questions of the inner relations, such as the filioque, are contested separately.
