Trinity Sunday

Trinity Sunday is celebrated on the first Sunday after Pentecost when Christians celebrate the mystery of the Holy Trinity, one God in three persons. In scripture, God reveals himself in three persons: God the Father, Jesus the Son, and the Holy Spirit. Our prayers are offered to the Father, through Jesus the Son, in the power of the Holy Spirit.

The term Trinity is used to to signify the central doctrine of the Christian religion that in the unity of the Godhead there are Three Persons, the Father, the Son, and the Holy Spirit, these Three Persons being truly distinct one from another.  The Father is God, the Son is God, and the Holy Spirit is God, and yet there are not three Gods but one God.  In this Trinity of Persons the Son is begotten of the Father by an eternal generation, and the Holy Spirit proceeds by an eternal procession from the Father and the Son. Yet, notwithstanding this difference as to origin, the Persons are co-eternal and co-equal: all alike are uncreated and omnipotent (Athanasian Creed c. 5th Cent.)

There are references to the Holy Trinity in Scripture. John begins his gospel, 'In the beginning was the Word, and the Word was with God, and the Word was God. All things came to be through him, and without him nothing came to be (John 1:1-3).'

The Psalmist sings, ‘By the Lord ’s word the heavens were made; by the breath of his mouth all their host (Psalms 33:6).'

When Jesus was baptized, "On coming up out of the water he saw the heavens being torn open and the Spirit, like a dove, descending upon him. And a voice came from the heavens, “You are my beloved Son; with you I am well pleased (Mk. 1:10-11)."'  

Most holy Trinity, one God in three Persons, we praise you and thank you for all of the favors you have bestowed upon us. We offer our whole being, especially our thoughts, words and deeds, so that we may be pleasing to you. Glory be to the Father, and to the Son, and to the Holy Spirit, God forever and ever. Amen!
