Fatima prayer to the Holy Trinity 
This prayer is based on the 20th century apparitions of Our Lady of Fatima, and is attributed to an angel who appeared to the visionaries. It is sometimes called the Angel Prayer. The apparitions of Fatima have been approved by the Holy Catholic Church, thus deemed worthy of belief.
In Catholic tradition, Saint Michael is the prince of the church of Jesus Christ and also the defender of Israel. Having revealed the Chaplet of Saint Michael to a Portuguese nun in the 18th Century, Saint Michael is often associated with being the angel that prepared the children shepherds for the visit of the Blessed Mother of God in Fatima, and thus to him it is attributed the prayer.
Words of the prayer:
- O 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 by which He is offended. By the infinite merits of the Sacred Heart of Jesus and the Immaculate Heart of Mary I beg the conversion of poor sinners.
