Whether a person contracts affinity through the marriage of a blood-relation?
Objections
❌ Objection 1 : It would seem that a person does not contract affinity through the marriage of a blood-relation. For "the cause of a thing being so is yet more so." Now the wife is not connected with her husband's kindred except by reason of the husband. Since then she does not contract affinity with her husband, neither does she contract it with her husband's kindred.
❌ Objection 2 : Further, if certain things be separate from one another and something be connected with one of them, it does not follow that it is connected with the other. Now a person's blood relations are separate from one another. Therefore it does not follow, if a certain woman be married to a certain man, that she is therefore connected with all his kindred.
❌ Objection 3 : Further, relations result from certain things being united together. Now the kindred of the husband do not become united together by the fact of his taking a wife. Therefore they do not acquire any relationship of affinity.
