One of the great devotions of the Church is the observance of nine 1st Friday's. This request was asked of Our Lord to St Margaret Mary with the promise: "I promise you in the excessive mercy of My Heart that My all-powerful love will grant all to those who communicate on the First Friday in nine consecutive months the grace of final penitence; they shall not die in My disgrace nor without receiving their Sacraments; My Divine Heart shall be their safe refuge in this last moment."
All that is required is attending Mass and receiving Holy Communion, and making a good confession eight days before or after, on the first Friday of each month for nine months in a row. It is a beautiful devotion to honor the Sacred Heart of Jesus, and it is a good reminder during this month of the Sacred Heart to persevere in this observance.
Our Lord to St Margaret Mary: “Behold the Heart which has so loved men that it has spared nothing, even to exhausting and consuming Itself, in order to testify Its love; and in return, I receive from the greater part only ingratitude, by their irreverence and sacrilege, and by the coldness and contempt they have for Me in the Eucharist. But what I feel most keenly is that it is hearts which are consecrated to Me that treat Me thus. Therefore, I ask of you that the Friday after the Octave of Corpus Christi be set apart for a special Feast to honor My Heart, by communicating on that day, and making to It a solemn act in order to make amends for the indignities which It has endured during the time It has been exposed on the altars. I promise you that My Heart will expand Itself to shed in abundance the influence of Its Divine Love upon those who shall thus honor It, and cause It to be honored.”
