Holy Trinity

On this Holy Trinity Sunday, we explore the foundational doctrine of the Christian faith: one God in three persons—Father, Son, and Holy Spirit. Today’s sermon unpacks Jesus’ conversation with Nicodemus in John 3, showing how the Triune God is not a mystery invented by theologians, but the God who reveals Himself in Word and Sacrament. We confess the Trinity not because it is reasonable, but because it is biblical—and because in this God, we find life and salvation.
