The Most Holy Trinity

Solemnity

Feast Day
May 31

The Solemnity of the Most Holy Trinity is celebrated on the Sunday after Pentecost. It honors the central mystery of the Christian faith: that there is one God in three divine Persons, Father, Son, and Holy Spirit, consubstantial and coeternal, distinct in their relations of origin and one in nature, will, and operation (CCC 232-260).

A votive Mass of the Most Holy Trinity is found in early medieval sacramentaries, including that of Alcuin of York (c. 800). Pope Saint John XXII (1316-1334) extended the feast to the universal Church in 1334, fixing it on the Sunday after Pentecost. Pope Saint Pius X raised it to the highest rank of the year (then double of the first class) in 1911.

The dogma of the Trinity was definitively formulated against Arianism at the First Council of Nicaea (325), confirming that the Son is consubstantial (homoousios) with the Father, and against Macedonianism at the First Council of Constantinople (381), which professed the divinity and procession of the Holy Spirit. The text now known as the Nicene-Constantinopolitan Creed (DS 150) is the principal liturgical confession of this faith.

Trinity Sunday is the climax of the season that began at Easter: the redemptive work of the Son sent by the Father has been completed in the gift of the Spirit at Pentecost, and the Church now contemplates the Triune God who has revealed himself in salvation history. Every liturgical action begins and ends with the Trinitarian formula (Matthew 28:19), and every blessing, sacrament, and prayer is offered to the Father, through the Son, in the Holy Spirit.
