"...I have been informed concerning certain other privileges conferred upon Saint Joseph by the Most High on account of his great holiness, which are especially important to those who ask his intercession in a proper manner. In virtue of these special privileges the intercession of Saint Joseph is most powerful: first, for attaining the virtue of purity and overcoming the sensual inclinations of the flesh; secondly, for procuring powerful help to escape sin and return to the friendship of God; thirdly, for increasing the love and devotion to most holy Mary; fourthly, for securing the grace of a happy death and protection against the demons in that hour; fifthly, for inspiring the demons with terror at the mere mention of his name by his clients; sixthly, for gaining health of body and assistance in all kinds of difficulties; seventhly, for securing issue of children in families. These and many other favors God confers upon those who properly and with good disposition seek the intercession of the spouse of our Queen, Saint Joseph. I beseech all the faithful children of the Church to be very devout to him and they will experience these favors in reality, if they dispose themselves as they should in order to receive and merit them."
