Father Juan Arintero, O.P., was a major force in reintroducing many of the mystics to the Catholic faithful. He worked closely with Mother Amparo of the Sacred Heart of Cantalapiedra, Spain, who revitalized the Poor Clare life in that country. He writes: “Holy Church keeps this Bread of Life in the ciborium, as though in the very center of her heart, where fervent and pure souls … stand guard near this Bread of Life.” - The Song of Songs, ch. VII, page 495
