Sacerdotalis Caelibatus §93
Sacerdotalis Caelibatus: On the Celibacy of the Priest
93 Your fraternal and kindly presence must fill up in advance the human loneliness of the priest, which is so often the cause of his discouragement and temptations. (141) Before being the superiors and judges of your priests, be their teachers, fathers, friends, their good and kind brothers always ready to understand, to sympathize and to help. Encourage your priests in every possible way to be your personal friends and to be very open with you. This will not weaken the relationship of juridical obedience; rather it will transform it into pastoral love so that they will obey more willingly, sincerely and securely. If they have a filial trust in you, your priests will be able in time to open up their souls and to confide their difficulties in you in the certainty that they can rely on your kindness to be protected from eventual defeat, without a servile fear of punishment, but in the filial expectation of correction, pardon and help, which will inspire them to resume their difficult journey with a new confidence.
