Sacerdotalis Caelibatus §34
Sacerdotalis Caelibatus: On the Celibacy of the Priest
34 Our Lord and Master has said that "in the resurrection they neither marry nor are given in marriage, but are like angels in heaven." (66) In the world of man, so deeply involved in earthly concerns and too often enslaved by the desires of the flesh, (67) the precious and almost divine gift of perfect continence for the kingdom of heaven stands out precisely as "a special token of the rewards of heaven"; (68) it proclaims the presence on earth of the final stages of salvation (69) with the arrival of a new world, and in a way it anticipates the fulfillment of the kingdom as it sets forth its supreme values which will one day shine forth in all the children of God. This continence, therefore, stands as a testimony to the ever-continuing progress of the People of God toward the final goal of their earthly pilgrimage, and as a stimulus for all to raise their eyes to the things above, "where Christ is seated at the right hand of God" and where "our life is hid with Christ in God" until it appears "with him in glory." (70)
