Celebrated one week after Pentecost each year, Trinity Sunday marks the conclusion of the first half of the Church Year (the "festival half," including Christmas, Easter, and Pentecost). It is also particularly significant to our congregation, as we bear the name Trinity.
Trinity Sunday is a celebration of the great mystery that God has revealed to us regarding His divine nature, that He is one God in three persons: the Father, the Son, and the Holy Spirit. This mystery cannot be fully comprehended by fallen man, yet we confess what God has spoken to us in His work and worshipo Him as He was revealed Himself to us.
Trinity Sunday includes the confession of the Athanasian Creed the longest of the three ecumenical creeds. In the Athanasian Creed we repeat the tructh of the divine nature, that God is Father, Son , and Holy Spirit, ad yet there are not three gods but one God.
Among the many hums of praise that the church sings to the Lord is a special category known as doxology. The word doxology comes from the Greek , meanig "a wod of glory. A doxology is a hymn, or more commonly, one verse of a longer hymn, that is a song of praise directly addredssed to the Trinity. God the Father, Son, and Holy Spirit.
