Feast of the Holy Trinity, also called Trinity Sunday, Christian feast in honour of the Trinity, celebrated in Western liturgical churches on the Sunday following Pentecost (the 50th day after Easter). It is known that the feast was celebrated on this day from as early as the 10th century. Celebration of the feast gradually spread in the churches of northern Europe, and in 1334 Pope John XXII approved it for the entire church. In the church year, Anglican and Lutheran churches date the Sundays that follow this feast “after Trinity”; the Roman liturgy dates these Sundays “after Pentecost.” In Eastern Orthodoxy the first day of the three-day Pentecost feast is known as Trinity Sunday.
Fatima prayer to the Holy Trinity
Most Holy Trinity,
Father, Son and Holy Spirit,
I adore Thee profoundly.
I offer Thee the most precious Body, Blood, Soul
and Divinity of Jesus Christ,
present in all the tabernacles of the world,
in reparation for the outrages,
sacrileges and indifferences whereby He is offended.
And through the infinite merits of His Most Sacred Heart
and the Immaculate Heart of Mary,
I beg of Thee the conversion of poor sinners.
Prayer to the Holy Trinity
Glory be to the Father,
Who by His almighty power and love created me,
making me in the image and likeness of God.
Glory be to the Son,
Who by His Precious Blood delivered me from hell,
and opened for me the gates of heaven.
Glory be to the Holy Spirit,
Who has sanctified me in the sacrament of Baptism,
and continues to sanctify me
by the graces I receive daily from His bounty.
Glory be to the Three adorable Persons of the Holy Trinity,
now and forever.
To the Trinity Dwelling in the Soul
O Most Holy Trinity, I adore Thee who are dwelling by Thy grace within my soul.
O Most Holy Trinity, who art dwelling by Thy grace within my soul, make me love Thee more and more.
O Most Holy Trinity, who art dwelling by Thy grace within my soul, sanctify me more and more.
Abide with me, O Lord; be Thou my true joy.
Novena to the Holy Trinity
I adore Thee, O my God, one God in three Persons; I annihilate myself before Thy Majesty. Thou alone art being, life, truth, beauty, and goodness. I glorify Thee, I praise Thee, I thank Thee, and I love Thee, all incapable and unworthy as I am, in union with Thy dear Son Jesus Christ, our Saviour and our Father, in the mercifulness of His heart and through His infinite merits. I wish to serve Thee, to please Thee, to obey Thee, and to love Thee always, in union with Mary Immaculate, Mother of God and our mother, loving also and serving my neighbour for Thy sake.
Therefore, give me Thy Holy Spirit to enlighten, correct, and guide me in the way of Thy commandments, and in all perfection, until we come to the happiness of heaven, where we shall glorify Thee for ever.
Glory be (7 times)
