"True love alone has the power to unite the wills of men.."

Pope St. Pius X, a member of the Third Order of St. Francis:

"For to be right and good, worship of the Mother of God ought to spring from the heart; acts of the body have here neither utility nor value if the
acts of the soul have no part in them. Now these latter can only have one object, which is that we should fully carry out what the divine Son of
Mary commands. For if true love alone has the power to unite the wills of men, it is of the first necessity that we should have one will with Mary to
serve Jesus our Lord. What this most prudent Virgin said to the servants at the marriage feast of Cana she addresses also to us: "Whatsoever he shall
say to you, do ye" (John ii., 5). Now here is the word of Jesus Christ: "If you would enter into life, keep the commandments" (Mt. xix., 17). Let
them each one fully convince himself of this, that if his piety towards the Blessed Virgin does not hinder him from sinning, or does not move his
will to amend an evil life, it is a piety deceptive and lying, wanting as it is in proper effect and its natural fruit." (Ad diem illum laetissimum, Feb 2, 1904:  para. 17)  Ad diem illum laetissimum
