The Solemnity of the Most Holy Trinity

Glory and Praise Forever!

The meaning of the celebration

+ A special feast in honor of the Most Holy Trinity was celebrated by the Benedictines in France prior to the year 1000.

+ Pope Alexander II (d. 1073) denied a request that this celebration be extended to the Universal Church, arguing that every liturgical celebration honors the Most Holy Trinity. More than one hundred fifty years later, 1334, however, Pope John XXII (d. 1334) finally chose to add this special feast to the calendar of the Church.

+ Celebrated on the Sunday after Pentecost, the Solemnity of the Most Holy Trinity provides the faithful with an opportunity to look back on the Paschal Triduum and Easter Seasons to reflect on the work of salvation remembered in these holy days in the light of the mystery of the Trinity.

+ The liturgical readings for this solemnity (in each of the three cycles presented in the Lectionary) contain a rich treasure of proclamation and adoration, inviting us to declare: “Glory to the Father, the Son and the Holy Spirit: to God who is, who was, and who is to come” (Alleluia verse).

For prayer and reflection

Jesus made manifest the face of God, in substance One and in persons Triune; God is all and only Love, in a subsistent relationship that creates, redeems and sanctifies all: Father and Son and Holy Spirit.”—Pope Francis
