Saint Peter Damian: Prayer to the Blessed Virgin Mary

Today, February 21, we celebrate the feast of Saint Peter Damian (1007-1072), Cardinal Bishop, and Doctor of the Church. Saint Peter is remembered for a life of penance and austerity, and preached rigorous reform. He was a man of integrity and zeal for the Lord, who confronted immorality and dishonesty wherever he found it—beginning within the Church ranks among the clergy. His writings remain instrumental in clarifying Church doctrine on issues such as Purgatory, the Eucharist, the Sacraments, and Christian virtues.

Especially devoted to Our Blessed Mother, Saint Peter Damian wrote about the Blessed Virgin, as well as composed many prayers to her grace. Below, an excerpt written by Saint Alphonsus de Liguori, summarizing some of Saint Peter Damian’s commentary on the Blessed Virgin, as well as a prayer to Mary penned by Saint Peter Damian.

From The Glories of Mary by Saint Alphonsus De Liguori

Peter Damian attests: "that by the prayers of Mary, who stood between the cross of the good thief and that of her Son, the thief was converted and saved, and thereby she repaid a former service." For, as other authors also relate, this thief had been kind to Jesus and Mary on their journey to Egypt; and this same office the Blessed Virgin has ever continued, and still continues, to perform.


And here we say, that although Mary, now in heaven, can no longer command her Son, nevertheless her prayers are always the prayers of a Mother, and, consequently, most powerful to obtain whatever she asks. And therefore, says Saint Peter Damian, "the Blessed Virgin can do whatever she pleases both in heaven and on earth. She is able to raise even those who are in despair to confidence; and he addresses her in these words: "All power is given to thee in heaven and on earth, and nothing is impossible to thee, who canst raise those who are in despair to the hope of salvation." And then he adds, that "when the Mother goes to seek a favour for us from Jesus Christ," (whom the Saint calls the golden altar of mercy, at which sinners obtain pardon), "her Son esteems her prayers so greatly, and is so desirous to satisfy her, that when she prays it seems as if she rather commanded than prayed, and was rather a Queen than a handmaid. Jesus is pleased thus to honour His beloved Mother, who honoured Him so much during her life, by immediately granting all that she asks or desires."

And thus Saint Peter Damian, reflecting on the great power of Mary, and begging her to take compassion on us, addresses her, saying: "O, let thy nature move thee, let thy power move thee; for the more thou art powerful, the greater should thy mercy be." O Mary, our own beloved advocate, since thou hast so compassionate a heart, that thou canst not even see the wretehed without being moved to pity; and since, at the same time, thou hast so great power with God that thou canst save all whom thou dost protect; disdain not to undertake the cause of us poor miserable creatures who place all our hope in thee. If our prayers cannot move thee, at least let thine own benign heart do so; or, at least, let thy power do so, since God has enriched thee with such great power, in order that the richer thou art in power to help us, the more merciful thou mayest be in the will to assist us.

Prayer of Saint Peter Damian to the Blessed Virgin Mary

O holy Virgin,
Mother of God,
help those who implore your assistance.
Turn toward us.
Have you perhaps forgotten us
because you have been elevated
to a position close to God?
No, certainly not.


You know well in what danger you left us.
You know the miserable condition of your servants.
No, it would not benefit such great mercy
as yours to forget such great misery as ours.

Turn toward us, then,
with your power,
for He who is powerful
has made you omnipotent in heaven and on earth.
For you, nothing is impossible.
You can raise even those who are in despair
to a hope of salvation.
There more powerful you are,
the greater should be your mercy.


Turn also to us in your love.
I know.
O Mary, that you are all kindness
and that you love us with a love
that no other love can surpass.
How often you appease the wrath of our Divine Judge,
when He is on the point of punishing us!

All the treasures of the mercy of God
are in your hands.
You will never cease to benefit us, I know,
for you are only seeking an opportunity
to save all sinners
and to shower your mercies upon them.
Your glory is increased when,
through you,
penitents are forgiven and reach heaven.


Turn, then, toward us,
so that we may also be able to go
and see you in heaven.
For the greatest glory that we can have,
after seeing God,
will be to see you,
to love you,
and to be under your protection.
So be pleased to grant our prayer;
for your beloved Son wishes to honour you
by refusing nothing that you ask.
Amen.
