The Most Holy Trinity is a central doctrine in Christianity, describing the nature of God as three distinct persons in one divine essence: God the Father, God the Son (Jesus Christ), and God the Holy Spirit. Each person is fully and equally God, yet there is only one God, not three. This mystery reflects God’s relational nature, where the Father creates, the Son redeems, and the Holy Spirit sanctifies. The feast of the Most Holy Trinity, celebrated on the Sunday after Pentecost, invites believers to reflect on the profound mystery of God’s unity and diversity, and His active presence in the world.
The Canadian Conference of Catholic Bishops (CCCB) has decreed that this is a Holy Day of Solemnity to be observed in Canada.
