The Doctrine of the Trinity is a teaching which affirms that:

The Latin 'Trinitas' is a translation of a Greek word first found in Theophilus of Antioch about 180 AD. The first creed in which it appears in that of Gregory Thaumaturgus in his work of 270 AD.
After much bitter controversy, the teaching was finally accepted by the Christian Churches at the Council of Nicea in 325 AD. The Creed agreed upon at Nicaea remains the basic statement of Christian faith. It is the formula still used today by The Eastern and Oriental Orthodox, the Lutheran, Anglican, Roman Catholic, and many Protestant Churches.
According to a Roman Catholic Encyclopaedia article entitled 'Dogmatic Theology' :

"The dogma of God's threefold personality, traces of which may be found in the Old Testament, can be conclusively proved from the New Testament and Tradition."
