Trinity Sunday

Trinity Sunday celebrates the central Christian understanding of God as one God in three persons, Father, Son, and Holy Spirit. It comes after the great events of the church year (Christmas, Easter, Pentecost) as a moment to worship the God revealed through all of them. The Trinity is a mystery the church confesses rather than fully explains, a God who is love in his very being, an eternal relationship of self-giving love.

Matthew 28:19

“Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.”

Trinity Sunday is observed with worship focused on the nature of God, often using the historic creeds. It opens the long season of Ordinary Time that follows.

Trinity Sunday is one thread in the wider rhythm of the church year.
