Whether the precepts of temperance are suitably given in the Divine law?

Objections

Objection 1 : It would seem that the precepts of temperance are unsuitably given in the Divine law. Because fortitude is a greater virtue than temperance, as stated above (Question [123], Article [12]; Question [141], Article [8]; FS, Question [66], Article [4]). Now there is no precept of fortitude among the precepts of the decalogue, which are the most important among the precepts of the Law. Therefore it was unfitting to include among the precepts of the decalogue the prohibition of adultery, which is contrary to temperance, as stated above (Question [154], Articles [1],8).
Objection 2 : Further, temperance is not only about venereal matters, but also about pleasures of meat and drink. Now the precepts of the decalogue include no prohibition of a vice pertaining to pleasures of meat and drink, or to any other species of lust. Neither, therefore, should they include a precept prohibiting adultery, which pertains to venereal pleasure.
Objection 3 : Further, in the lawgiver's intention inducement to virtue precedes the prohibition of vice, since vices are forbidden in order that obstacles to virtue may be removed. Now the precepts of the decalogue are the most important in the Divine law. Therefore the precepts of the decalogue should have included an affirmative precept directly prescribing the virtue of temperance, rather than a negative precept forbidding adultery which is directly opposed thereto.
