Obj. 3:  Further, the Divine Law should encourage mercy more even than the human law.  But according to human laws those who ill-treat their servants and maidservants are severely punished:  and the worse treatment of all seems to be that which results in death.  Therefore it is unfittingly commanded (Ex. 21:20, 21) that “he that striketh his bondman or bondwoman with a rod, and they die under his hands . . . if the party remain alive a day . . . he shall not be subject to the punishment, because it is his money.”

Obj. 4:  Further, the dominion of a master over his slave differs from that of the father over his son (Polit. i, 3).  But the dominion of master over slave gives the former the right to sell his servant or maidservant.  Therefore it was unfitting for the Law to allow a man to sell his daughter to be a servant or handmaid (Ex. 21:7).

Obj. 5:  Further, a father has power over his son.  But he who has power over the sinner has the right to punish him for his offenses.  Therefore it is unfittingly commanded (Deut. 21:18, seqq.) that a father should bring his son to the ancients of the city for punishment.

Obj. 6:  Further, the Lord forbade them (Deut. 7:3, seqq.) to make marriages with strange nations; and commanded the dissolution of such as had been contracted (1 Esdras 10).  Therefore it was unfitting to allow them to marry captive women from strange nations (Deut. 21:10, seqq.).

Obj. 7:  Further, the Lord forbade them to marry within certain degrees of consanguinity and affinity, according to Lev. 18.  Therefore it was unsuitably commanded (Deut. 25:5) that if any man died without issue, his brother should marry his wife.

Obj. 8:  Further, as there is the greatest familiarity between man and wife, so should there be the staunchest fidelity.  But this is impossible if the marriage bond can be sundered.  Therefore it was unfitting for the Lord to allow (Deut. 24:1-4) a man to put his wife away, by writing a bill of divorce; and besides, that he could not take her again to wife.

Objection 9:  Further, just as a wife can be faithless to her husband, so can a slave be to his master, and a son to his father.  But the Law did not command any sacrifice to be offered in order to investigate the injury done by a servant to his master, or by a son to his father.  Therefore it seems to have been superfluous for the Law to prescribe the “sacrifice of jealousy” in order to investigate a wife’s adultery (Num. 5:12, seqq.).  Consequently it seems that the Law put forth unsuitable judicial precepts about the members of the household.

On the contrary, It is written (Ps. 18:10):  “The judgments of the Lord are true, justified in themselves.”
