Pope John XXIII
Sacerdotii Nostri Primordia §26
Priest's Chastity As Help to Others
26 What great benefits are conferred on human society by men like this who are free of the cares of the world and totally dedicated to the divine ministry so that they can employ their lives, thoughts, powers in the interest of their brethren! How valuable to the Church are priests who are anxious to preserve perfect chastity! For We agree with Our predecessor of happy memory, Pius XI, in regarding this as the outstanding adornment of the Catholic priesthood and as something "that seems to Us to correspond better to the counsels and wishes of the Most Sacred Heart of Jesus, so far as the souls of priests are concerned." (38) Was not the mind of John Mary Vianney soaring to reach the counsels of this same divine charity when he wrote this lofty sentence: "Is the priesthood love of the Most Sacred Heart of Jesus?" (39)
