Marks of authentic devotion to our Lady
106. First, true devotion to our Lady is interior, that is, it comes from within the mind and the heart and follows from the esteem in which we hold her, the high regard we have for her greatness, and the love we bear her.
107. Second, it is trustful, that is to say, it fills us with confidence in the Blessed Virgin, the confidence that a child has for its loving Mother. It prompts us to go to her in every need of body and soul with great simplicity, trust and affection. We implore our Mother's help always, everywhere, and for everything. We pray to her to be enlightened in our doubts, to be put back on the right path when we go astray, to be protected when we are tempted, to be strengthened when we are weakening, to be lifted up when we fall into sin, to be encouraged when we are losing heart, to be rid of our scruples, to be consoled in the trials, crosses and disappointments of life. Finally, in all our afflictions of body and soul, we naturally turn to Mary for help, with never a fear of importuning her or displeasing our Lord.
108. Third, true devotion to our Lady is holy, that is, it leads us to avoid sin and to imitate the virtues of Mary. Her ten principal virtues are: deep humility, lively faith, blind obedience, unceasing prayer, constant self-denial, surpassing purity, ardent love, heroic patience, angelic kindness, and heavenly wisdom.
109. Fourth, true devotion to our Lady is constant. It strengthens us in our desire to do good and prevents us from giving up our devotional practices too easily. It gives us the courage to oppose the fashions and maxims of the world, the vexations and unruly inclinations of the flesh and the temptations of the devil. Thus a person truly devoted to our Blessed Lady is not changeable, fretful, scrupulous or timid. We do not say however that such a person never sins or that his sensible feelings of devotion never change. When he has fallen, he stretches out his hand to his Blessed Mother and rises again. If he loses all taste and feeling for devotion, he is not at all upset because a good and faithful servant of Mary is guided in his life by faith in Jesus and Mary, and not by feelings.
110. Fifth, true devotion to Mary is disinterested. It inspires us to seek God alone in his Blessed Mother and not ourselves. The true subject of Mary does not serve his illustrious Queen for selfish gain. He does not serve her for temporal or eternal well-being but simply and solely because she has the right to be served and God alone in her. He loves her not so much because she is good to him or because he expects something from her, but simply because she is lovable. That is why he loves and serves her just as faithfully in weariness and dryness of soul as in sweet and sensible fervour. He loves her as much on Calvary as at Cana. How pleasing and precious in the sight of God and his holy Mother must these servants of Mary be, who serve her without any self-seeking. How rare they are nowadays! It is to increase their number that I have taken up my pen to write down what I have been teaching with success both publicly and in private in my missions for many years.
111. I have already said many things about the Blessed Virgin and, as I am trying to fashion a true servant of Mary and a true disciple of Jesus, I have still a great deal to say, although through ignorance, inability, and lack of time, I shall leave infinitely more unsaid.
112. But my labour will be well rewarded if this little book falls into the hands of a noble soul, a child of God and of Mary, born not of blood nor the will of the flesh nor of the will of man. My time will be well spent if, by the grace of the Holy Spirit, after having read this book he is convinced of the supreme value of the solid devotion to Mary I am about to describe. If I thought that my guilty blood could help the reader to accept in his heart the truths that I set down in honour of my dear Mother and Queen, I, her most unworthy child and slave, would use it instead of ink to write these words. I would hope to find faithful souls who, by their perseverance in the devotion I teach, will repay her for the loss she has suffered through my ingratitude and infidelity.
113. I feel more than ever inspired to believe and expect the complete fulfilment of the desire that is deeply engraved on my heart and what I have prayed to God for over many years, namely, that in the near or distant future the Blessed Virgin will have more children, servants and slaves of love than ever before, and that through them Jesus, my dear Lord, will reign more than ever in the hearts of men.
114. I clearly foresee that raging beasts will come in fury to tear to pieces with their diabolical teeth this little book and the one the Holy Spirit made use of to write it, or they will cause it at least to lie hidden in the darkness and silence of a chest and so prevent it from seeing the light of day. They will even attack and persecute those who read it and put into practice what it contains. But no matter! So much the better! It even gives me encouragement to hope for great success at the prospect of a mighty legion of brave and valiant soldiers of Jesus and Mary, both men and women, who will fight the devil, the world, and corrupt nature in the perilous times that are sure to come.
