Sacerdotalis Caelibatus §4
Sacerdotalis Caelibatus: On the Celibacy of the Priest
4 Our attention has rested particularly on the objections which have been and are still made in various forms against the retention of sacred celibacy. in virtue of Our apostolic office We are obliged by the importance, and indeed the complexity, of the subject to give faithful consideration to the facts and the problems they involve, at the same time bringing to them—as it is Our duty and Our mission to do—the light of truth which is Christ. Our intention is to do in all things the will of Him who has called Us to this office and to show what we are in the Church: the servant of the servants of God.
