On the Catholic Priesthood
Haerent Animo, Apostolic Exhortation
"It is his duty to uproot unfruitful plants and to sow useful ones, to
water the crop and to guard lest the enemy sow cockle among it.
Consequently, the priest must be careful not to allow an unbalanced
concern for personal perfection to lead him to overlook any part of the
duties of his office which are conducive to the welfare of others. These
duties include the preaching of the word of God, the hearing of
confessions, assisting the sick, especially the dying, the instruction
of those who are ignorant of the faith, the consolation of the
sorrowing, leading back the erring, in a word, the imitation in every
respect of Christ who went about doing good and healing all that were
oppressed by the devil."
