Sacerdotalis Caelibatus §44
Sacerdotalis Caelibatus: On the Celibacy of the Priest
44 Holy virginity is a very special gift. Nevertheless, the whole present-day Church, solemnly and universally represented by the pastors responsible for her welfare (with due respect, as We have said, for the discipline of the Eastern Churches), manifested her absolute faith "in the Holy Spirit that the grace of leading a celibate life, so desirable in the priesthood of the New Testament, will be readily granted by God the Father if those who by ordination share the priesthood of Christ humbly and earnestly ask it together with the whole Church." (85)
