What is Trinity Sunday?
Quick answer
Trinity Sunday is celebrated the Sunday after Pentecost, set aside specifically to worship and confess the Triune God — Father, Son, and Holy Spirit, one in being, three in person.
Most of the Christian year focuses on one act of God; Trinity Sunday steps back to adore the eternal life of God himself.
The Nicene Creed, hymns to the Trinity, and texts like Matthew 28:19 anchor the day.
For believers, it is a reminder that the gospel is not just a transaction but an invitation into the eternal love of the Triune God.
