"Whoever desires Jesus must go to Mary and whoever finds Mary will most certainly find Jesus."
— St Alphonsus Liguori
It is desirable that the practice of...devotion to Mary should be rounded off and given the distinctive character which has been taught by St. Louis-Marie de Montfort under the title of "The True Devotion" and which is enshrined in his two books, True Devotion to the Blessed Virgin and The Secret of Mary.
That Devotion requires the formal entry into a compact with Mary, whereby one gives to her one's whole self, with all its thoughts and deeds and possessions, both spiritual and temporal, past, present, and future, without the reservation of the smallest part or slightest little thing. In a word, the giver places himself in a condition equivalent to that of a slave possessing nothing of his own, and wholly dependent on, and utterly at the disposal of Mary.
But the earthly slave is far freer than the slave of Mary. The former remains master of his thoughts and inner life, and thus may be free in everything that matters to him. But the surrender to Mary bears with it everything: each thought, the movements of the soul, the hidden riches, the inmost self. All - on to the final breath - is committed to her that she may expend it all for God. It is a sort of martyrdom, the sacrifice of self to God, with Mary as the altar of that sacrifice. How conformed, indeed, to the sacrifice of Christ himself, which likewise began in Mary's bosom, was publicly confirmed in the arms of Mary uplifted in the presentation, embraced every moment of his life, and was consummated on Calvary on the cross of Mary's heart.
The True Devotion is inaugurated by a formal Act of Consecration, but it consists principally in the subsequent living of that Consecration. The True Devotion must represent not an act but a state. Unless Mary takes possession of all the life, and not merely of minutes and hours of that life, the Act of Consecration-even though frequently repeated-has but the value of a passing prayer. It is like a tree which has been planted, but which has never taken root.
But this does not mean that the mind has to remain ever fixed upon the Consecration. Just as one's physical life is governed by one's breathing or by the beating of one's heart, even though these operations are not consciously viewed, so it is with the True Devotion. Even though not adverted to, it works incessantly on the life of the soul. It suffices if the idea of Mary's ownership is now and then made vivid by deliberate thought, by acts and ejaculations; provided that the fact of one's dependence on her remains permanently acknowledged, always at least vaguely present to the mind, and put into force in a general way in all the circumstances of one's life.
If there is a warmth in all this, it can be a help. But if not, it does not affect the value of the Devotion. Oftentimes, in fact, warmth makes things soft and not dependable.
Mark this well: the True Devotion does not depend on fervour or emotions of any kind. Like every lofty edifice, it may at times burn in sunshine, while its deep foundations are cold like the rock they rest on.
Reason is commonly cold. The best resolve may be icy. Faith itself can be chill as a diamond. Yet these are the foundations of the True Devotion. Set in them, the latter will abide; and the frost and the storm, which cause mountains to crumble, will only leave it the stronger.
The graces which have attended the practice of the True Devotion, and the position it has attained in the devotional life of the Church, would reasonably appear to indicate that it represents an authentic message from Heaven, and this is precisely what St. Louis-Marie de Montfort claimed it to be. He attached to it immense promises, and he asserted most positively that those promises would be fulfilled if the conditions which govern them are fulfilled.
And as to the everyday experience: speak to those whose practice of the Devotion is more than a surface affair, and see with what complete conviction they speak of what it has done for them. Ask them if they may not be the victims of their feelings or imagination. Always they will declare that there is no question of it; the fruits have been too evident to admit of their being deceived.
If the sum of the experiences of those who teach, and understand, and practise the True Devotion is of value, it seems unquestionable that it deepens the interior life, sealing it with the special character of unselfishness and purity of intention. There is a sense of guidance and protection: a joyful certainty that now one's life is being employed to the best advantage. There is a supernatural outlook, a definite courage, a firmer faith, which make one a mainstay of any enterprise. There is a tenderness and a wisdom which keep strength in its proper place. There is, too, the protectress of them all, a sweet humility. Graces come which one cannot but realise are out of the common. Frequently, there is a call to a great work, which is patently beyond one's merits and natural capacity. Yet with it come such helps as enable that glorious but heavy burden to be borne without faltering. In a word, in exchange for the splendid sacrifice which is made in the True Devotion by selling oneself into this species of slavery, there is gained the hundredfold which is promised to those who despoil themselves for the greater glory of God. When we serve, we rule; when we give, we have; when we surrender ourselves we are victors.
Some persons appear to reduce their spiritual life very simply to a matter of selfish gain or loss. These are disconcerted by the suggestion that they should abandon their treasures even to the Mother of our souls. Such as the following is heard: "If I give everything to Mary, will I not at the hour of my departure from this life stand empty-handed before my Judge, and therefore perhaps have to go for a vast time into Purgatory?" To this, a commentator quaintly answers: "No, not at all, since Mary is present at the Judgment!" The thought contained in this remark is profound.
But the objection to making the Consecration is usually due less to a purely selfish outlook than to perplexity. There is difficulty in understanding how those things for which one is bound in duty to pray,such as one's family, one's friends, one's country, the Pope, etc., will fare if one makes the unreserved gift of one's spiritual treasures. Let all these misgivings be put aside, and let the Consecration be boldly made. Everything is safe with Our Lady. She is the guardian of the treasures of God himself. She is capable of being the guardian of the concerns of those who place their trust in her. So together with the assets of your life, cast all its liabilities - its obligations and duties - into that great sublime heart of hers. In her relations with you, she acts in a manner as if she had no other child but you. Your salvation, your sanctification, your multiple needs are peremptorily present to her. When you pray for her intentions, you yourself are her first intention.
But here, where one is being urged to make sacrifice, is not the place to seek to prove that there is no loss whatever in the transaction. For to prove this would sap the very foundations of the offering and deprive it of the character of sacrifice on which its value depends. It will suffice to recall that once upon a time a multitude of ten or twelve thousand were in a desert, and were hungry. (Jn 6:1-14) In all that number only one person had brought food with him. What he possessed amounted to five loaves and two fishes and he was asked to give them up for the common good; and he did so with willingness. Then those few loaves and fishes were blessed and broken and distributed to the multitude. And in the end all that immense throng did eat, until they could eat no more; and among them he who had given the original seven items of food. And yet what remained over filled twelve baskets, full and to overflowing! Now supposing that individual had said: "What good will these few loaves and fishes be to so great a multitude? Besides, I require them for the members of my family here with me and oppressed by hunger. I cannot give." But no! He gave and he and his people received far more from the miraculous repast than they had contributed to it. And no doubt they had a form of claim to the twelve basketfuls, if they desired to assert it.
Such is always the way of Jesus and Mary with the princely soul which gives its possessions without reserve or stipulation. The gift avails to satisfy the wants of a vast throng. Yet, one's own needs and intentions, which had appeared to suffer, are filled to overflowing and still the Divine bounty lies scattered about.
Let us, then, hasten to Mary with our poor loaves and fishes, and press them into her arms, so that Jesus and she may multiply them to feed the souls of the millions hungering in the arid desert of this world.
The form of one's ordinary prayers and actions need not be changed as a result of the making of the Consecration. The customary paths of life may be pursued, and one may continue to pray for one's usual intentions and for all special purposes, but subject in future to Mary's good pleasure.
"Mary shows us her Divine Son and addresses to us the same invitation that she did of old to the serving men at Cana: 'Whatsoever he shall say to you, do ye.' (Jn 2:5) If at her command we pour into the vessels of Charity and Sacrifice the tasteless water of the thousand details of our everyday actions the miracle of Cana is renewed. The water is changed into a delicious wine, that is to say, into choicest graces for ourselves and for others." (Cousin)
