Sacerdotalis Caelibatus: On the Celibacy of the Priest
98 Venerable brothers, pastors of God's flock throughout the world, and dearly beloved priests, Our sons and brothers: as We come to the end of this letter which We have addressed to you, We invite you, with a soul responsive to Christ's great love, to turn your eyes and heart with renewed confidence and filial hope to the most loving Mother of Jesus and Mother of the Church, and to invoke for the Catholic priesthood her powerful and maternal intercession. In her the People of God admire and venerate the image of the Church, and model of faith, charity and perfect union with Him. May Mary Virgin and Mother obtain for the Church, which also is hailed as virgin and mother, (150) to rejoice always, though with due humility, in the faithfulness of her priests to the sublime gift of holy virginity they have received, and to see it flourishing and appreciated ever more and more in every walk of life, so that the army of those who "follow the divine Lamb wherever He goes'' (151) may increase throughout the earth.
