Whether matrimony is fittingly defined in the text?

❌ Objection 1 : It would seem that matrimony is unfittingly defined in the text* (Sent. iv, D, 27). [*The definition alluded to is as follows: "Marriage is the marital union of man and woman involving living together in undivided partnership."] For it is necessary to mention matrimony in defining a husband, since it is the husband who is joined to the woman in matrimony. Now "marital union" is put in the definition of matrimony. Therefore in these definitions there would seem to be a vicious circle.

❌ Objection 2 : Further, matrimony makes the woman the man's wife no less than it makes the man the woman's husband. Therefore it should not be described as a "marital union" rather than an uxorial union.

❌ Objection 3 : Further, habit [consuetudo] pertains to morals. Yet it often happens that married persons differ very much in habit. Therefore the words "involving their living together [consuetudinem] in undivided partnership" should have no place in the definition of matrimony.

❌ Objection 4 : Further, we find other definitions given of matrimony, for according to Hugh (Sum. Sent. vii, 6), "matrimony is the lawful consent of two apt persons to be joined together." Also, according to some, "matrimony is the fellowship of a common life and a community regulated by Divine and human law"; and we ask how these definitions differ.
