Second—Writers frequently discuss the secret cause of the marvelous success which marks the growth of the Catholic Church everywhere in spite of the most formidable opposition. Some ascribe this progress to her thorough organization; others to the far-seeing wisdom of her chief pastors. Without undervaluing these and other auxiliaries, I incline to the belief that, under God, the Church has no tower of strength more potent than the celibacy of her clergy. The unmarried Priest, as St. Paul observes (1 Cor. vii.), is free to give his whole time undivided to the Lord, and can devote his attention not to one or two children, but to the entire flock whom he has begotten in Christ Jesus, through the Gospel; while the married minister is divided between the cares of his family and his duties to the congregation. “A single life,” says Bacon, “doth well with churchmen; for, charity will hardly water the ground where it must first fill a pool.”(530) Third—The world has hitherto been converted by unmarried clergymen, and only by them will it continue to be converted. St. Francis Xavier and St. Francis de Sales could not have planted the faith in so many thousands of souls if they were accompanied on their journeys by their wives and children. Of all the gems that adorn the priestly diadem, none is so precious and indispensable in the eyes of the people as the peerless jewel of chastity. Without this pearl the voice of a Hyacinthe “becomes as sounding brass and a tinkling cymbal;” with it, the humblest missioner gains the hearts of multitudes. Everybody is aware of the numerous conversions to Christianity effected by St. Francis Xavier in Japan in the sixteenth century. After the lapse of many years from the death of St. Francis, when a French squadron was permitted to enter the Japanese ports, a native Christian, named Peter, having learned that French Priests were on board, put their faith to the test by proposing to them these three questions: “Are you followers of the great Father in Rome? Do you honor Mary, the Blessed Virgin? Have you wives?” The French priests having satisfied their interrogator on these points, and especially on the last, Peter and his companions fell at the missioners’ feet, exclaiming with delight “Thanks, thanks! they are virgins and true disciples of our Apostle Francis.”(531)
