One of the themes in today’s Brievary is the Priesthood of Jesus. In the Old Testament priests offered sacrifices for sin (usually animals) to God. As the ultimate High Priest, Jesus offered himself to God the Father as a perfect sacrifice of obedience on our behalf. This he did on Good Friday. Jesus’ whole life however was one perfect act of obedience to the Father’s Will. As he said in John 4:24 “My food is to do the will of my Father.”
Today’s Brievary states: “We offer our prayers and ourselves in union with him.” The place above all where this happens is in the Mass. This is especially evident at the end of the Eucharistic Prayer when the priest holds up the Body and Blood of Jesus and says: “Through him [Jesus], with him [Jesus], in him [Jesus], in the unity of the Holy Spirit, all glory and honour is yours Almighty Father, forever and ever” to which the entire congregation respond AMEN.
Another commendable practice is to say a Morning Offering in which we dedicate the whole day to God. This following prayer was written by St Therese of Lisieux:
O my God ! I offer Thee all my actions of this day for the intentions and for the glory of the Sacred Heart of Jesus. I desire to sanctify every beat of my heart, my every thought, my simplest works, by uniting them to Its infinite merits ; and I wish to make reparation for my sins by casting them into the furnace of Its Merciful Love. O my God! I ask thee for myself and for those whom I hold dear, the grace to fulfill perfectly Thy Holy Will, to accept for love of Thee the joys and sorrows of this passing life, so that we may one day be united together in Heaven for all Eternity. Amen.
