Adiutricem §24

²⁴ And so, in Mary, God has given us the most zealous guardian of Christian unity. There are, of course, more ways than one to win her protection by prayer, but as for Us, We think that the best and most effective way to her favor lies in the Rosary. We have elsewhere brought it to the attention of the devout Christian and not least among the advantages of the Rosary is the ready and easy means it puts in his hands to nurture his faith, and to keep him from ignorance of his religion and the danger of error.
