Indeed, celibacy has a many-faceted suitability for the priesthood. For the whole priestly mission is dedicated to the service of a new humanity which Christ, the victor over death, has aroused through his Spirit in the world and which has its origin "not of blood, nor of the will of the flesh, nor of the will of man but of God (Jn 1:13). Through virginity, then, or celibacy observed for the Kingdom of Heaven,(37) priests are consecrated to Christ by a new and exceptional reason. They adhere to him more easily with an undivided heart,(38) they dedicate themselves more freely in him and through him to the service of God and men, and they more expeditiously minister to his Kingdom and the work of heavenly regeneration, and thus they are apt to accept, in a broad sense, paternity in Christ. In this way they profess themselves before men as willing to be dedicated to the office committed to them-namely, to commit themselves faithfully to one man and to show themselves as a chaste virgin for Christ(39) and thus to evoke the mysterious marriage established by Christ, and fully to be manifested in the future, in which the Church has Christ as her only Spouse.(40) They give, moreover, a living sign of the world to come, by a faith and charity already made present, in which the children of the resurrection neither marry nor take wives.(41)
