Trinity Sunday

In the second half of the year, the six months from Trinity to Advent, the Holy Ghost whose reign begins at Pentecost, comes to repeat to us what our Lord Himself has taught in the first half, the six months from Advent to Trinity Sunday.

The fundamental truth on which everything in the Christian religion rests is the dogma of the Holy Trinity. In the course of the cycle, having called to our minds in order, God the Father, Author of creation, God the Son, Author of Redemption, and God the Holy Ghost, Author of our sanctification, the Church today, before all else, recapitulates the great mystery by which we acknowledge and adore the Unity of Nature and Trinity of Person in Almighty God.

"As soon as we have celebrated the coming of the Holy Ghost", says Abbot Rupert, "we hail in song the feast of the Holy Trinity, the following Sunday, a well-chosen place in

the calendar, for immediately after the descent of the Holy Spirit, preaching and conversion began and faith through baptism and confession in the Name of the Father and of the Son and of the Holy Ghost."

The dogma of the Holy Trinity is affirmed, in the liturgy, on every hand. It is in the Name of the Father and of the Son and of the Holy Ghost that we begin the Mass and the Divine Office, and that we confer the Sacraments. All the psalms end with the Gloria, the hymns with the Doxology, and the prayers by a conclusion in honor of the three Divine Persons. Twice during the Mass we are reminded that it is to the Holy Trinity that the Mass is being offered. The dogma of the Trinity is expressed in the very fabric of our churches.
