Holy Trinity Sunday is a Christian feast day celebrating the doctrine of the Holy Trinity - the three Persons of God: the Father, the Son, and the Holy Spirit. Observed on the Sunday following Pentecost, it honors the triune nature of God. This day emphasizes the mystery and unity of the Godhead. Liturgical readings and hymns on this day reflect on the Trinity. Holy Trinity Sunday invites the faithful to contemplate the profound reality of one God in three divine Persons.
