On First Saturdays, there is Benediction of the Blessed Sacrament at 7:30am, followed by mass at 8:00am. This is preceded by all-night Exposition of the Blessed Sacrament if the previous day was the First Friday of the Month.
The observance of the first Saturday in honor of
the Immaculate Heart of Mary is intended to make reparation to it for the sins
of mankind. This devotion was revealed by the Blessed Virgin to three children,
Francisco, Jacinta and Lucia to whom she appeared at Fatima, Portugal, in 1917.
On June 13, 1917, Our Lady specifically stated in speaking to Lucia: "Jesus
wants to make use of you to make me known and loved. He wants to establish in
the world devotion to my Immaculate Heart.
Our Lady repeated this in the July 13th
apparition when, after the vision of Hell that was granted to the three
children, she said: "You have seen Hell, where the souls of poor sinners
go. To save them, God wishes to establish in the world devotion to my Immaculate
Heart. If what I say to you is done, many souls will be saved and there will be
peace." Our Lady asks for reparation. "There are so many souls whom
the Justice of God condemns for sins committed against me, that I have come to
ask reparation."
"O my Jesus, I offer this for love
of Thee, for the conversion of sinners, and in reparation for the sins committed
against the Immaculate Heart of Mary. (Sacrifice Prayer)
