26 "Laid hold of by Christ" (43) unto the complete abandonment of one's entire self to Him, the priest takes on a closer likeness to Christ, even in the love with which the eternal Priest has loved the Church His Body and offered Himself entirely for her sake, in order to make her a glorious, holy and immaculate Spouse. (44) The consecrated celibacy of the sacred ministers actually manifests the virginal love of Christ for the Church, and the virginal and supernatural fecundity of this marriage, by which the children of God are born, "not of blood, nor of the will of the flesh." (45 46)
