4 Take the proper means necessary for the diminution of these quarrelsome souls. Bear well in mind, Venerable Brethren, the Apostle's warning to Timothy: "Do not lay hands hastily upon anyone." In fact, haste in admitting men to Sacred Orders naturally opens the way to a multiplication of people in the sanctuary who do not increase joy . We know that there are cities and dioceses where, far from there being any reason to lament the dearth of clergy, the clergy greatly exceed the needs of the faithful. Venerable Brethren, what reason is there for imposing hands so frequently? In those places where the lack of clergy is no sufficient reason for haste in so important a matter and the clergy are more numerous than the requirements demand, nothing excuses from the most delicate caution and the greatest exactitude in selecting those who are to receive the sacerdotal honor. The eagerness of the aspirants is no excuse for haste. The priesthood that Jesus Christ instituted for the salvation of souls is by no means a human profession or office which anyone desiring it for any reason can say he has a right to receive. Therefore, let the Bishops call young men to sacred orders, not according to the desires or pretexts of the aspirants, but, as the Council of Trent prescribes, according to the needs of the dioceses. In this task they can select only those who are really suitable and dismiss those who have inclinations contrary to the priestly vocation. The most dangerous of these inclinations are a disregard for discipline and that pride of mind which fosters it.
