Reverence And Devotion To Jesus In The Eucharist

With every fiber of his being Francis burned with love for the Sacrament of the Body of the Lord. It left him overcome with wonder for so great a condescension and merciful love. He was said to be disconsolate if, even once, he could not hear daily Mass, even if it was impossible to do so. He received communion often and with such devotion as to make others experience a like devotion. He rendered every reverence to so venerable a sacrament, offering the sacrifice of his whole self; and when he received the Immolated Lamb of God, he immolated his own spirit in that fire which was always burning on the altar of his heart.
