71 Moreover, the appointed ends are the same. The first of these is to give glory to the Heavenly Father. From His birth to His death Jesus Christ burned with zeal for the divine glory; and the offering of His blood upon the cross rose to heaven in an odor of sweetness. To perpetuate this praise, the members of the Mystical Body are united with their divine Head in the eucharistic sacrifice, and with Him, together with the Angels and Archangels, they sing immortal praise to God and give all honor and glory to the Father Almighty.
