The saint who gave us this prayer is best known for his love of the poor.
While St. Francis is well known for his love of the poor and most vulnerable of society, he also had an intense love of Jesus in the Holy Eucharist.
In his Letter to All the Friars, St. Francis gave the following exhortation that clearly displays his passion,
Let the entire man be seized with fear; let the whole world tremble; let heaven exult when Christ, the Son of the Living God, is on the altar in the hands of the priest. O admirable height and stupendous condescension! O humble sublimity! O sublime humility! that the Lord of the universe, God and the Son of God, so humbles Himself that for our salvation he hides himself under a morsel of bread.
Whenever he caught sight of a Catholic church in the distance, St. Francis was known to kneel down and give praise to God. Often he would say the following words that he passed on to his friars.
We adore you, O Lord Jesus Christ, in this church and all the churches of the world, and we bless you, because by your holy Cross you have redeemed the world. Amen
