Our Lord wished to have a group of men who would have the freedom to give full time to His service; hence He ordained in order that they who served the altar were to live by the altar. Celibacy in the Latin Rite stresses this quality of total dedication. The priest is a celibate in order that he might not have the cares of family and, therefore, not be afraid to minister to people in plague or to give the last rites to soldiers dying in battle. St. Paul, speaking of celibacy as a spur to undivided service, writes: "And I would have you free from concern. He who is unmarried is concerned with God's claim, asking how he is to please God" (I Corinth. 7:32).
Chastity, however, is not something cold or negative. It is, as Francis Thompson called it, "a passionless passion, a wild tranquillity." A man cannot live without love, though he can live without romantic love or the Eros. The divine command, "increase and multiply" (Gen. 1:28) may be verified not only with reference to the body, but also to the soul. There can be increase of man in the cultural, moral, and religious spheres. The priest is called a "father," because he begets souls in Christ. As St. Paul wrote to the Galatians: "My little children, I am in travail over you afresh, until I can see Christ's image formed in you" (Gal. 4:19). The purer the mirror of his humanity is, the better he reflects the image of Christ.
Though a priest is called a father, nevertheless, he is also a "mother" of children. Our Blessed Lord used two analogies to describe His attitude toward the city that He loved, and also to all humanity. He said that He loved Jerusalem as a hen who gathers her chickens, but the city refused His love. The night of the Last Supper, He used the similitude of a mother about to bring forth a child, implying that He would be in labor in His Crucifixion, but would bring forth new life in His Resurrection.
