Christians believe that God is experienced as three persons, the Father, the Son and the HolySpirit. The Father, Son and Spirit are all equal, all eternal and all God, yet they are distinct persons.
The Catechism of the Catholic Church states, "The mystery of the Most Holy Trinity is the central mystery of Christian faith and life. It is the mystery of God in himself."
Significance of the Trinity in Christian belief and worship
• Priests bless their congregations “In the name of the Father, the Son and of the Holy Spirit.”
• People are baptised and married “In the name of the Father, the Son and of the Holy Spirit.”
• Most traditional worship services include the reciting of either the Nicene Creed or the Apostles’ Creed, both of which describe belief in the Trinity.
