Whether parish priests may lawfully enter religion?

❌ Objection 1 : It would seem that parish priests cannot lawfully enter religion. For Gregory says (Past. iii, 4) that "he who undertakes the cure of souls, receives an awful warning in the words: 'My son, if thou be surety for thy friend, thou hast engaged fast thy hand to a stranger'" (Prov. 6:1); and he goes on to say, "because to be surety for a friend is to take charge of the soul of another on the surety of one's own behavior." Now he who is under an obligation to a man for a debt, cannot enter religion, unless he pay what he owes, if he can. Since then a priest is able to fulfil the cure of souls, to which obligation he has pledged his soul, it would seem unlawful for him to lay aside the cure of souls in order to enter religion.

❌ Objection 2 : Further, what is lawful to one is likewise lawful to all. But if all priests having cure of souls were to enter religion, the people would be left without a pastor's care, which would be unfitting. Therefore it seems that parish priests cannot lawfully enter religion.

❌ Objection 3 : Further, chief among the acts to which religious orders are directed are those whereby a man gives to others the fruit of his contemplation. Now such acts are competent to parish priests and archdeacons, whom it becomes by virtue of their office to preach and hear confessions. Therefore it would seem unlawful for a parish priest or archdeacon to pass over to religion.
