St. Margaret Mary Alacoque
Life(1647-1690)
Of the several saints who have popularized devotion to the Sacred Heart of Jesus, St. Margaret Mary Alacoque is the best known. A nun of the Order of the Visitation, it was she to whom the Lord gave the most specific instructions about encouraging reparation to His Sacred Heart for injuries done to His redemptive love. Margaret Alacoque was born at L’Autecoeur, Burgundy, France, to a prominent French official named Claude Alacoque. She was the fifth of his seven children. Her education was limited by circumstances: tutoring by her godmother, and two years in a convent school. But acquaintance with the life of nuns through observing her school teachers, the Poor Clare Franciscans, made a positive impression on her naturally devout personality. A rheumatic ailment kept her abed between the ages of 11 and 15. Because of her illness she had to return to the family home. Here she and her mother Philiberte had much grief to bear, for after her father’s death one of her sisters and her brother-in-law assumed total command of the household, bore down upon her mother, and were unduly harsh with her, often forbidding her even to go to church. As might be expected, the householding couple tried to marry Margaret off. Her response was to double her prayers and acts of self-denial. But when she began to gather together the neglected children of the town to instruct them, this charity, too, won scant favor from her family.
At 22, Margaret was finally able to receive the sacrament of confirmation, taking as her additional name, Mary. Free now to choose her own destiny, she entered the Visitation Convent at Paray-le-Monial in 1671. There she would spend the rest of her life. It is comforting to learn that Sister Margaret Mary was naturally rather quiet, slow and clumsy. Most of us are like that! But there was no doubt about her genuine piety. Christ rewarded her prayerfulness by a series of apparitions and revelations. He told her especially that He was troubled by the coldness and ingratitude of so many of those whom He had lovingly saved by His death. He asked her to help make up for this ingratitude both by her own prayers, good works and sufferings, and by persuading others to follow her example.
First, He commissioned her to spread devotion to his Sacred Heart, which He ordered to be pictured as a flaming heart, wounded and crowned with thorns. Next, He urged her to promote frequent Holy Communion, especially on the first Friday of each month, and a holy hour of Eucharistic adoration on the previous evening. (Frequent communion was rare in her day.) Finally, He asked that she work towards the establishment of a liturgical feastday of the Sacred Heart. He also instructed her to become a sacrificial victim for the shortcomings of the nuns of her own community, and to tell the nuns she had been assigned such a task. Understandably, the Visitation sisters were not all pleased to learn God’s will in this matter; however, they became more accepting. Indeed, the convent became, and still remains, a center for propagating that public and private devotion to the Sacred Heart that we are still familiar with today.
The special calling of St. Margaret Mary to warn the faithful against coldness and ingratitude towards Jesus makes me wish that she might be living among us today. More Catholics receive frequent Holy Communion now than did in 17th-century France, but one can wonder how well prepared they are to do so, and therefore how respectful they really are towards their Eucharistic King. One can ask, too, how many Catholics make a practice nowadays of paying regular visits to the Blessed Sacrament, or taking part in Eucharistic adoration, and how they dress and behave in church. Do they display due reverence for the Real Presence, or a cavalier neglect? We adore the “Heart that has so loved men.” May we therefore renew constantly our resolution to atone for the world’s irreverence towards It by our own deep and demonstrated devotion to Jesus in the Blessed Sacrament! -- Father Robert F. McNamara
Scripture(Eph 3:14-19)
I kneel before the Father, from whom every family in heaven and on earth is named, that he may grant you in accord with the riches of his glory to be strengthened with power through his Spirit in the inner self, and that Christ may dwell in your hearts through faith; that you, rooted and grounded in love, may have strength to comprehend with all the holy ones what is the breadth and length and height and depth, and to know the love of Christ that surpasses knowledge, so that you may be filled with all the fullness of God.
Writings
(Year A). You are ever the dear mother of my heart, which cherishes you in the Heart of Our Loving Savior with all the love of which it is capable. I flatter myself that you do not doubt this, since I keep nothing secret from you. I take special pleasure in recounting to you the mercies of Our Sovereign towards the most ungrateful of all His creatures. His generosity to me is so great that it is impossible for me to find words to describe it to Your Charity. But this I will say: He deals with me like a father enraptured with His little child. During my retreat especially He seems to take pleasure in overwhelming me with His sweet consolations. But I cannot make up my mind to relish them in this life, finding my happiness only in the pleasure He takes in doing good to us. Crosses, contempt, suffering, afflictions: these are the true treasures of the lovers of Jesus Christ crucified. Pray, dear Mother, that He may not leave me for a moment without these in the accomplishment of His holy will which is so manifest in the sufferings of Reverend Father de la Colombiere. For when I was once recommended him to God's goodness, I heard these words "The servant is not greater than his Master." There is nothing more profitable than conformity with his dear Master. Although according to the human way of thinking his health would be more for the glory of God, his sufferings have given God incomparably more glory. For there is a time for everything: a time for suffering and a time for action, a time for sowing and a time for watering and cultivating." This is what he is doing at present. For the Lord is pleased to give an inestimable value to his sufferings because they are so closely joined with His own. Later on He will let their merits fall as a heavenly dew upon this harvest which he has sown in so many places, and make it grow and bring forth fruit in His holy love. Let us obey, then, dear Mother, the orders of our Sovereign, and admit that, although what He does seems to us harsh and severe, He is good and just in all He does and always merits our praise and love. If you only knew how much He is urging me to love Him with a love of conformity to His suffering life! He wants me to make sacrifices continually. He Himself furnishes me with occasions for making them in the employment He has given me. I note with pleasure that each act is a new sacrifice for me because of the repugnance He gives me the grace of feeling in this employment. That repugnance gives such satisfaction to this Spirit, Master of mine, that He often compels me to say, in spite of my lower nature, that it is good to go on, by the strength of His love, contrary to our own inclinations, without any pleasure or satisfaction except that of not having any. For it must suffice for us that Our Lord is satisfied in any manner that pleases Him. I would find it a far greater joy to speak to you than write to you; it seems to me I would express the sentiments of my heart better orally. I am getting much consolation from reading your letters and, although I am very glad no one thinks of me any more, I believe Our Lord wants you to think of me and wishes me never to forget you. For the love of the Sacred Heart, look sometimes at the little note you are keeping, for He takes pleasure in that. How much obliged I should be, good Mother, were you to do me the favor of burning everything you have received from me! Let us do all we can to procure honor and love for the Sacred Heart of Our Spouse, Who makes me entirely yours forever in His holy love. (To Mother de Saumaise, at Moulins; November, 1680)
Musical Selection(Benedictines of Mary)
O Heart of Jesus, Heart of God
O source of boundless love,
By Angels praised, by Saints adored,
From their bright thrones above.
The poorest, saddest heart on earth
May claim Thee for its own,
O burning, throbbing Heart of Christ,
Thou art too little known.
A mother may forsake her child,
A father prove untrue;
But for my soul and for my love
Was Thy Heart piercèd through.
The purest, deepest earthly love,
What is it, Lord, to Thine?
O grant a spark of that great fire
To this cold heart of mine.
In Thee, dear Jesus, I confide
For Thou hast called to me,
That I should learn Thy meekness
And sweet humility.
Upon the Sacred Heart of God
Shall I cast all my care!
For in Thy gracious Heart I find
My refuge from despair.
The world is cold and life is sad;
I crave the blessed rest Of those
who lay their weary heads
Upon Thy sacred Breast.
But love is stronger far than death,
And who can love like Thee,
O Savior, whose most loving Heart
Broke on the cross for me?
Collect
Lord God,
pour out on us that spirit
with which you so remarkably endowed Saint Margaret Mary;
grant that we may know the love of Christ,
which surpasses all knowledge,
and be filled with all the fullness of the divine life.
We make our prayer through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
