Trinity Sunday

Trinity Sunday celebrates and honouring the Holy Trinity—the Father, the Son, and the Holy Spirit—as the central mystery of the Christian faith. This day provides an opportunity for worshippers to reflect on the nature of God, as well as the unity and diversity of the divine relationship. Trinity Sunday also marks the beginning of a liturgical period called "Ordinary Time" in which the focus of worship shifts from the life and teachings of Jesus Christ to the mission of the Church in the world.

The concept of the Holy Trinity can be traced back to the early Christian Church, with the first recorded use of the term by theologian Tertullian in the third century. In Australia, the significance of Trinity Sunday spans across diverse Christian denominations, encompassing the Anglican, Catholic, Uniting, and other Protestant churches. Although its origins and doctrines may differ among these denominations, they all come together to recognize and celebrate the Trinity as the foundation of their shared Christian faith.

Trinity Sunday is observed through special church services, prayers, and hymns, which may include readings from the Holy Scriptures and reflections on the doctrine of the Holy Trinity. Sermons and discussions often explore the theological implications of the Trinity and its importance in individual understanding of God and faith. Trinity Sunday is observed on the first Sunday after Pentecost, which in Australia and the southern hemisphere typically falls between the months of May and June.
