Whether adoption is rightly defined?

❌ Objection 1 : It would seem that adoption is not rightly defined: "Adoption is the act by which a person lawfully takes for his child or grandchild and so on one who does not belong to him." For the child should be subject to its father. Now, sometimes the person adopted does not come under the power of the adopter. Therefore adoption is not always the taking of someone as a child.

❌ Objection 2 : Further, "Parents should lay up for their children" (2 Cor. 12:14). But the adoptive father does not always necessarily lay up for his adopted child, since sometimes the adopted does not inherit the goods of the adopter. Therefore adoption is not the taking of someone as a child.

❌ Objection 3 : Further, adoption, whereby someone is taken as a child, is likened to natural procreation whereby a child is begotten naturally. Therefore whoever is competent to beget a child naturally is competent to adopt. But this is untrue, since neither one who is not his own master, nor one who is not twenty-five years of age, nor a woman can adopt, and yet they can beget a child naturally. Therefore, properly speaking, adoption is not the taking of someone as a child.

❌ Objection 4 : Further, to take as one's child one who is not one's own seems necessary in order to supply the lack of children begotten naturally. Now one who is unable to beget, through being a eunuch or impotent, suffers especially from the absence of children of his own begetting. Therefore he is especially competent to adopt someone as his child. But he is not competent to adopt. Therefore adoption is not the taking of someone as one's child.

❌ Objection 5 : Further, in spiritual relationship, where someone is taken as a child without carnal procreation, it is of no consequence whether an older person become the father of a younger, or "vice versa," since a youth can baptize an old man and "vice versa." Therefore, if by adoption a person is taken as a child without being carnally begotten, it would make no difference whether an older person adopted a younger, or a younger an older person; which is not true. Therefore the same conclusion follows.

❌ Objection 6 : Further, there is no difference of degree between adopted and adopter. Therefore whoever is adopted, is adopted as a child; and consequently it is not right to say that one may be adopted as a grandchild.

❌ Objection 7 : Further, adoption is a result of love, wherefore God is said to have adopted us as children through charity. Now we should have greater charity towards those who are connected with us than towards strangers. Therefore adoption should be not of a stranger but of someone connected with us.
