The Prayer to Saint Michael the Archangel usually refers to one specific Catholic prayer to Michael the Archangel, among the various prayers in existence that are addressed to him. It falls within the realm of prayers on spiritual warfare. From 1886 to 1964, this prayer was recited after Low Mass in the Catholic Church, although not incorporated into the text or the rubrics of the Mass. Other prayers to Saint Michael have also been officially approved and printed on prayer cards. Prayer to St. Michael the Archangel by Pope Leo XIII:

Historical context

The threat to the church at the time was the Italian government's campaign against the Papal States. The 1890 text was composed and published twenty years after the capture of Rome had deprived the Pope of the last vestige of his temporal sovereignty. The papal residence at the Quirinal Palace had been converted into that of King Victor Emmanuel II of Italy.

In the Leonine Prayers

In 1886, Pope Leo XIII added a Prayer to Saint Michael to the Leonine Prayers, which he had directed to be prayed after Low Mass two years earlier.

The English translation which was used in Ireland is quoted in James Joyce's novel Ulysses. Variant English translations include: "Holy Michael", "Saint Michael", "defend us in battle", "malice and snares", "may God rebuke him", "thrust into hell", "all evil spirits", "prowl about the world seeking the ruin", and "roam throughout the world seeking the ruin".

The prayer's opening words are similar to the Alleluia verse for Saint Michael’s feasts on 8 May and 29 September in the Roman Missal of the time, which ran:

History

The 'Leonine Prayers' originated in 1884, when Pope Leo XIII ordered certain prayers to be said after Low Mass, in defense of the independence of the Holy See. God's help was sought for a satisfactory solution to the loss of the Pope's temporal sovereignty, which deprived him of the independence felt to be required for effective use of his spiritual authority. The prayer to St Michael described above was added to the Leonine Prayers in 1886.The opposition between the Roman Catholic Church and the Freemasons was true and radical at the time so that, in 1887, an anti-Masonic League, with papal blessing and under the patronage of Saint Michael, had an admission document that read: ‘We request that the pious Christian women who belong to this holy League add a Our Father and an Hail Mary to their morning prayers with this invocation: 'Saint Michael the Archangel, pray for us and protect the Church against the Masonic sects that form the army of Satan'." As quoted in Lino Sacchi, Massoneria. Una introduzione, Lindau, serie "I leoni", Torino 2024, p. 304. ,

The Pope's status as a temporal leader was restored in 1929 by the creation of the State of Vatican City, and in the following year, Pope Pius XI ordered that the intention for which these prayers should from then on be offered was "to permit tranquility and freedom to profess the faith to be restored to the afflicted people of Russia".

The practice of reciting this and the other Leonine prayers after Mass was officially suppressed by the 26 September 1964 Instruction Inter oecumenici which came into effect on 7 March 1965.

Removing the obligation to recite this prayer (along with the three Hail Marys, the Hail Holy Queen, and the prayer for the Church) after Low Mass did not mean forbidding its use either privately or publicly in other circumstances. Thirty years later, Pope John Paul II recommended its use, saying:

On 29 September 2018, Pope Francis asked Catholics everywhere to pray the Rosary each day during the following month of October and to conclude it with the ancient prayer "Sub tuum praesidium" and the Leonine prayer to Saint Michael. He asked them "to pray that the Holy Mother of God place the Church beneath her protective mantle: to preserve her from the attacks by the devil, the great accuser, and at the same time to make her more aware of the faults, the errors and the abuses committed in the present and in the past, and committed to combating without any hesitation, so that evil may not prevail".

A month earlier, Pope Francis called more generically to "a penitential exercise of prayer and fasting" in view of scandals concerning Catholic Church sexual abuse cases.

Exorcism prayer A quite different prayer to Saint Michael was included in an exorcism formula published in the 1890−1891 edition of Acta Sanctae Sedis for use by bishops and by those priests authorized to perform exorcisms. To any of these who devoutly recited the formula daily Pope Leo XIII granted on 18 May 1890 a partial indulgence on each day and a plenary indulgence whenever they did so for a whole month.

This "Exorcism against Satan and the apostate angels" () opens with some verses from the Psalms and then presents a long prayer to Saint Michael followed immediately by the actual prayer of exorcism, which began with a series of ten conjurations.

The exorcism formula, with its incorporated prayer to Saint Michael, was inserted into the 1898 edition of the Roman Ritual.
