THE MYSTERY OF THE MOST HOLY TRINITY IS THE CENTRAL MYSTERY OF CHRISTIAN FAITH AND LIFE. IT IS THE MYSTERY OF GOD IN HIMSELF. IT IS THEREFORE THE SOURCE OF ALL THE OTHER MYSTERIES OF FAITH, THE LIGHT THAT ENLIGHTENS THEM.
The doctrine of the Holy Trinity is the central pillar of the Catholic faith.
The Trinity denotes the unity of the Godhead as one Being but having three Persons - God the Father, God the Son, and God the Holy Spirit. The doctrine of the Trinity apart from being the central doctrine of the Catholic Church, also holds an important place in the history of the Christian Church as a whole. In the Council of Nicaea (325 AD) the matter of the Trinity was reaffirmed by the Church as the fundamental doctrine of the Christian faith, hence rejecting the teachings of Arianism that held that since Jesus was begotten of the Father, He is not of equal status in divinity but was a created being. Arianism also held that since Jesus was created, He was not co-eternal with the Father. The Athanasian creed that proceeded from the decision of the Council of Nicaea affirmed the doctrine of the Trinity. It succinctly states in its relevant part thus:
"And the Catholic Faith is this, that we worship one God in Trinity and Trinity in Unity. Neither confounding the Persons, nor dividing the Substance. For there is one Person of the Father, another of the Son, and another of the Holy Ghost. But the Godhead of the Father, of the Son and of the Holy Ghost is all One, the Glory Equal, the Majesty Co-Eternal."
