Whether children should be received in religion?

Objections

Objection 1 : It would seem that children ought not to be received in religion. Because it is said (Extra, De Regular. et Transeunt. ad Relig., cap. Nullus): "No one should be tonsured unless he be of legal age and willing." But children, seemingly, are not of legal age; nor have they a will of their own, not having perfect use of reason. Therefore it seems that they ought not to be received in religion.
Objection 2 : Further, the state of religion would seem to be a state of repentance; wherefore religion is derived [*Cf. Question [81], Article [1]] from "religare" [to bind] or from "re-eligere" [to choose again], as Augustine says (De Civ. Dei x, 3 [*Cf. De Vera Relig. lv]). But repentance does not become children. Therefore it seems that they should not enter religion.
Objection 3 : Further, the obligation of a vow is like that of an oath. But children under the age of fourteen ought not to be bound by oath (Decret. XXII, qu. v, cap. Pueri and cap. Honestum.). Therefore it would seem that neither should they be bound by vow.
Objection 4 : Further, it is seemingly unlawful to bind a person to an obligation that can be justly canceled. Now if any persons of unripe age bind themselves to religion, they can be withdrawn by their parents or guardians. For it is written in the Decretals (XX, qu. ii, can. Puella) that "if a maid under twelve years of age shall take the sacred veil of her own accord, her parents or guardians, if they choose, can at once declare the deed null and void." It is therefore unlawful for children, especially of unripe age, to be admitted or bound to religion.
