President Obama's requirement that abortion, sterilization, and contraception be included in all health plans has been called "unconscionable", by the USCCB. It is time for all believers to start praying to St. Michael the Archangel. Remember he's the one who threw Satan into hell. Obviously, Satan is prowling the earth. It's time to pray.
There are different stories about the origin of this prayer. But like all legends, there are some similarities and somewhere therein likes the truth. These are from Wikipedia.
An article in the Roman journal Ephemerides Liturgicae (V. LXIX, pages 54–60) in 1955 gave an account in Latin and Italian of how the St. Michael prayer developed. Footnote nine of this account quotes an article in another Italian journal called La Settimana del Clero in 1947 by Fr. Domenico Pechenino who worked at the Vatican during the time of Leo XIII, in which he stated:
"I do not remember the exact year. One morning the great Pope Leo XIII had celebrated a Mass and, as usual, was attending a Mass of thanksgiving. Suddenly, we saw him raise his head and stare at something above the celebrant's head. He was staring motionlessly, without batting an eye. His expression was one of horror and awe; the colour and look on his face changing rapidly. Something unusual and grave was happening in him.
"Finally, as though coming to his senses, he lightly but firmly tapped his hand and rose to his feet. He headed for his private office. His retinue followed anxiously and solicitously, whispering: 'Holy Father, are you not feeling well? Do you need anything?' He answered: 'Nothing, nothing.' About half an hour later, he called for the Secretary of the Congregation of Rites and, handing him a sheet of paper, requested that it be printed and sent to all the ordinaries around the world. What was that paper? It was the prayer that we recite with the people at the end of every Mass. It is the plea to Mary and the passionate request to the Prince of the heavenly host, (St. Michael: Saint Michael the Archangel, defend us in battle) beseeching God to send Satan back to hell."
According to the same article in Ephemerides Liturgicae, Cardinal Giovanni Nasalli Rocca di Corneliano wrote in his Litteris Pastoralibus pro Quadragesima (Pastoral Letters for Lent) that "the sentence 'The evil spirits who wander through the world for the ruin of souls' has a historical explanation that was many times repeated by his private secretary, Monsignor Rinaldo Angeli. Leo XIII truly saw, in a vision, demonic spirits who were congregating on the Eternal City (Rome). The prayer that he asked all the Church to recite was the fruit of that experience. He would recite that prayer with strong, powerful voice: we heard it many a time in the Vatican Basilica. Leo XIII also personally wrote an exorcism that is included in the Roman Ritual. He recommended that bishops and priests read these exorcisms often in their dioceses and parishes. He himself would recite them often throughout the day."
In the late twentieth century, more vivid stories circulated among traditionalist Catholics, according to which in that century Satan would be particularly powerful. They recounted that Pope Leo XIII was climbing the steps to the altar when he suddenly stopped, stared fixedly at something in the air and with a terrible look on his face, collapsed to the floor (some accounts say he fell shrieking). The Pope was carried off by those around him to another room where he came around. As one rendition of the story tells it:
"When asked what had happened, he explained that, as he was about to leave the foot of the altar, he suddenly heard voices - two voices, one kind and gentle, the other guttural and harsh. They seemed to come from near the tabernacle. As he listened, he heard the following conversation:
The guttural voice, the voice of Satan in his pride, boasted to Our Lord: "I can destroy your Church."
The gentle voice of Our Lord: "You can? Then go ahead and do so."
Satan: "To do so, I need more time and more power."
Our Lord: "How much time? How much power?"
Satan: "75 to 100 years, and a greater power over those who will give themselves over to my service."
Our Lord: "You have the time, you will have the power. Do with them what you will."
A variant of the story of the vision of Leo XIII was given by Father William Saunders in the Arlington Catholic Herald of 2 October 2003: "Pope Leo XIII (d. 1903) had a prophetic vision of the coming century of sorrow and war. After celebrating Mass, the Holy Father was conferring with his cardinals. Suddenly, he fell to the floor. The cardinals immediately called for a doctor. No pulse was detected, and the Holy Father was feared dead. Just as suddenly, Pope Leo awoke and said, 'What a horrible picture I was permitted to see!' In this vision, God gave Satan the choice of one century in which to do his worst work against the Church. The devil chose the 20th century. So moved was the Holy Father from this vision that he composed the prayer to St. Michael the Archangel
And here is the prayer:
O glorious Archangel St. Michael, Prince of the heavenly host, defend us in battle, and in the struggle which is ours against the principalities and Powers, against the rulers of this world of darkness, against spirits of evil in high places. Come to the aid of men, whom God created immortal, made in his own image and likeness, and redeemed at a great price from the tyranny of the devil.
Fight this day the battle of the Lord, together with the holy angels, as already thou hast fought the leader of the proud angels, Lucifer, and his apostate host, who were powerless to resist thee, nor was there place for them any longer in Heaven. But that cruel, that ancient serpent, who is called the devil or Satan, who seduces the whole world, was cast into the abyss with all his angels.
Behold, this primeval enemy and slayer of man has taken courage, Transformed into an angel of light, he wanders about with all the multitude of wicked spirits, invading the earth in order to blot out the name of God and of his Christ, to seize upon, slay and cast into eternal perdition souls destined for the crown of eternal glory. This wicked dragon pours out, as a most impure flood, the venom of his malice on men of depraved mind and corrupt heart, the spirit of lying, of impiety, of blasphemy, and the pestilent breath of impurity, and of every vice and iniquity.
These most crafty enemies have filled and inebriated with gall and bitterness the Church, the spouse of the Immaculate Lamb, and have laid impious hands on her most sacred possessions.
In the Holy Place itself, where has been set up the See of the most holy Peter and the Chair of Truth for the light of the world, they have raised the throne of their abominable impiety, with the iniquitous design that when the Pastor has been struck, the sheep may be scattered.
Arise then, O invincible prince, bring help against the attacks of the lost spirits to the people of God, and bring them the victory.
The Church venerates thee as protector and patron; in thee holy Church glories as her defense against the malicious powers of this world and of hell; to thee has God entrusted the souls of men to be established in heavenly beatitude.
Oh, pray to the God of peace that He may put Satan under our feet, so far conquered that he may no longer be able to hold men in captivity and harm the Church. Offer our prayers in the sight of the Most High, so that they may quickly conciliate the mercies of the Lord; and beating down the dragon, the ancient serpent, who is the devil and Satan, do thou again make him captive in the abyss, that he may no longer seduce the nations. Amen.
