Of Legal Relationship, Which Is by Adoption

Of Legal Relationship, Which Is by Adoption — St. Thomas Aquinas asks: Whether adoption is rightly defined?; Whether a tie that is an impediment to marriage is contracted through adoption?; Whether legal relationship is contracted only between the adopting father and the adopted child?.

We must now consider legal relationship which is by adoption. Under this head there are three points of inquiry:

Article 1: Whether adoption is rightly defined?

Art imitates nature and supplies the defect of nature where nature is deficient. Hence just as a man begets by natural procreation, so by positive law which is the art of what is good and just, one person can take to himself another as a child in likeness to one that is his child by nature, in order to take the place of the children he has lost, this being the chief reason why adoption was introduced. And since taking implies a term "wherefrom," for which reason the taker is not the thing taken, it follows that the person taken as a child must be a stranger. Accordingly, just as natural procreation has a term "whereto," namely the form which is the end of generation, and a term "wherefrom," namely the contrary form, so legal generation has a term "whereto," namely a child or grandchild, and a term "wherefrom," namely, a stranger. Consequently the above definition includes the genus of adoption, for it is described as a "lawful taking," and the term "wherefrom," since it is said to be the taking of "a stranger," and the term "whereto," because it says, "as a child or grandchild ."

Article 2: Whether a tie that is an impediment to marriage is contracted through adoption?

Relationship is an impediment to marriage. Now a kind of relationship results from adoption, namely legal relationship, as evidenced by its definition, for "legal relationship is a connection arising out of adoption." Therefore adoption results in a tie which is an impediment to marriage.

Further, the same is proved by the authorities quoted in the text (Sent. iv, D, 42).

The Divine law especially forbids marriage between those persons who have to live together lest, as Rabbi Moses observes (Doc. Perp. iii, 49), if it were lawful for them to have carnal intercourse, there should be more room for concupiscence to the repression of which marriage is directed. And since the adopted child dwells in the house of his adopted father like one that is begotten naturally human laws forbid the contracting of marriage between the like, and this prohibition is approved by the Church. Hence it is that legal adoption is an impediment to marriage. This suffices for the Replies to the first three Objections, because none of those things entails such a cohabitation as might be an incentive to concupiscence. Therefore they do not cause a relationship that is an impediment to marriage.

Article 3: Whether legal relationship is contracted only between the adopting father and the adopted child?

Legal relationship is more in agreement with carnal union or procreation than spiritual relationship is. But spiritual relationship passes to another person. Therefore legal relationship does so also.

Further, the same is proved by the authorities quoted in the text (Sent. iv, D, 42).

Legal relationship is of three kinds. The first is in the descending order as it were, and is contracted between the adoptive father and the adopted child, the latter's child grandchild and so on; the second is between the adopted child and the naturally begotten child; the third is like a kind of affinity, and is between the adoptive father and the wife of the adopted son, or contrariwise between the adopted son and the wife of the adoptive father. Accordingly the first and third relationships are perpetual impediments to marriage: but the second is not, but only so long as the adopted person remains under the power of the adoptive father, wherefore when the father dies or when the child comes of age, they can be married.
