Act of Adoration and Reparation
I ADORE Thee profoundly, O my Jesus, in Thy sacramental form;
I acknowledge Thee to be true God and true Man,
and by this act of adoration
I intend to atone for the coldness
of so many Christians who pass before Thy churches
and sometimes before the very Tabernacle in which Thou art pleased to remain at all hours with loving impatience to give Thyself to Thy faithful people,
and do not so much as bend the knee before Thee,
and who, by their indifference
proclaim that they grow weary of this heavenly manna,
like the people of Israel in the wilderness.
I offer Thee in reparation for this grievous negligence,
the Most Precious Blood which Thou didst shed from Thy five wounds,
and especially from Thy sacred Side,
and entering therein,
I repeat a thousand times with true recollection of spirit:
O Sacrament most holy!
O Sacrament divine!
All praise and all thanksgiving
be every moment Thine.
My God, I believe, I adore, I hope, and I love You. I ask pardon for those who do not believe, do not adore, do not hope, and do not love You.
Golden Arrow Prayer:
MAY the most holy, most sacred, most adorable, most incomprehensible and unutterable Name of God be always praised, blessed, loved, adored and glorified, in Heaven, on earth, and under the earth, by all the creatures of God, and by the Sacred Heart of Our Lord Jesus Christ in the Most Holy Sacrament of the Altar. Amen.
