One of the greatest means of salvation, and one of the surest signs of predestination, is unquestionably, the devotion to the Most Blessed Virgin Mary. All the holy doctors of the Church are unanimous in saying with St. Alphonsus Liguori: "A devout servant of Mary shall never perish."

The chief thing is to persevere faithfully until death in this devotion.

Can there be an easier or more adaptable practice for all than the recitation each day of three Ave Marias in honor of the privileges conferred by the Adorable Trinity on the Blessed Virgin?

One of the first to say the three Hail Marys and to recommend them to others was the illustrious St. Anthony of Padua. His special aim in this practice was to honor the spotless Virginity of Mary and to preserve a perfect purity of mind, heart and body in the midst of the dangers of the world. Many, like him, have felt its salutary effects.

Later on, St. Leonard of Port-Maurice, the celebrated missionary, had the three Ave Marias recited morning and evening in honor of Mary Immaculate, to obtain the grace of avoiding all mortal sins during the day or and night; moreover, he promised in a special manner eternal salvation to all those who proved constantly faithful to this practice.

After the example of these two great Franciscan Saints, St. Alphonsus Liguori adopted this pious practice and gave it his most ardent and powerful support. He counseled its use and even imposed it as a penance on those who had not adopted this good habit. The holy Doctor exhorts, in particular, parents, and confessors to watch carefully that children be faithful in reciting each day their three Hail Marys, morning and evening and recommended it to  all the devout young or old.

It is this Saint who suggested adding the aspiration after each Hail Mary: "By thy Immaculate Conception, O Mary, make my body pure and my soul holy."

This practice has been revealed to St. Melchtilde with the promise of a good death, if she was faithful to it every day.
