Whether boys and those who lack the use of reason can receive Orders?

Objections

Objection 1 : It would seem that boys and those who lack the use of reason cannot receive Orders. For, as stated in the text (Sent. iv, D, 25), the sacred canons have appointed a certain fixed age in those who receive Orders. But this would not be if boys could receive the sacrament of Orders. Therefore, etc.
Objection 2 : Further, the sacrament of Orders ranks above the sacrament of matrimony. Now children and those who lack the use of reason cannot contract matrimony. Neither therefore can they receive Orders.
Objection 3 : Further, act and power are in the same subject, according to the Philosopher (De Somn. et Vigil. i). Now the act of Orders requires the use of reason. Therefore the power of Orders does also.
