Pope John XXIII
Sacerdotii Nostri Primordia §25
Priest's Chastity As Help to Others
25 The ascetic way of life, by which priestly chastity is preserved, does not enclose the priest's soul within the sterile confines of his own interests, but rather it makes him more eager and ready to relieve the needs of his brethren. St. John Mary Vianney has this pertinent comment to make in this regard: "A soul adorned with the virtue of chastity cannot help loving others; for it has discovered the source and font of love—God." (26)
