"All our perfection consists in being conformed, united and consecrated to Jesus Christ; and therefore the most perfect of all devotions is, without any doubt, that which conforms, unites and consecrates us most perfectly to Jesus Christ. Now, Mary being the most conformed of all creatures to Jesus Christ, it follows that, of all devotions, that which most consecrates and conforms a soul to Our Lord is devotion to His Holy Mother, and that the more a soul is consecrated to Mary, the more will it be consecrated to Jesus ."

St. Louis Marie de Montfort,
True Devotion to the Blessed Virgin Mary, no. 120

Act of Consecration to Mary

Written by St. Maximilian Kolbe

O Immaculata, Queen of Heaven and earth, refuge of sinners and our most loving Mother, God has willed to entrust the entire order of mercy to you. I, (name), a repentant sinner, cast myself at your feet humbly imploring you to take me with all that I am and have, wholly to yourself as your possession and property. Please make of me, of all my powers of soul and body, of my whole life, death and eternity, whatever most pleases you.

If it pleases you, use all that I am and have without reserve, wholly to accomplish what was said of you: "She will crush your head," and, "You alone have destroyed all heresies in the world." Let me be a fit instrument in your immaculate and merciful hands for introducing and increasing your glory to the maximum in all the many strayed and indifferent souls, and thus help extend as far as possible the blessed kingdom of the most Sacred Heart of Jesus. For wherever you enter, you obtain the grace of conversion and growth in holiness, since it is through your hands that all graces come to us from the most Sacred Heart of Jesus.

V. Allow me to praise you, O sacred Virgin.

R. Give me strength against your enemies.
