Trinity Sunday

This Sunday, May 31, we celebrate Trinity Sunday, one of the seven principal feasts of the Church Year. Always observed on the First Sunday after Pentecost, Trinity Sunday invites us to glorify the mystery of God’s own life: Father, Son, and Holy Spirit—in Trinity of Persons and in Unity of Being.

The feast has been observed in the Western Church since the 14th century and is associated with Saint Thomas Becket, who was consecrated bishop on Trinity Sunday in 1162. His martyrdom helped popularize the feast, especially in England, where the Sundays following were once named “Sundays after Trinity," a tradition preserved in older prayer books and the Sarum Missal.

"Almighty God, you have revealed to your Church your eternal
Being of glorious majesty and perfect love as one God in
Trinity of Persons: Give us grace to continue steadfast in the
confession of this faith, and constant in our worship of you,
Father, Son, and Holy Spirit; for you live and reign, one God,
now and for ever. Amen."
(Collect of the Holy Trinity, BCP pg. 251)
