Whether, in this life, perfection consists in the observance of the commandments or of the counsels?

Objections

Objection 1 : It would seem that, in this life, perfection consists in the observance not of the commandments but of the counsels. For our Lord said (Mt. 19:21): "If thou wilt be perfect, go sell all [Vulg.: 'what'] thou hast, and give to the poor . . . and come, follow Me." Now this is a counsel. Therefore perfection regards the counsels and not the precepts.
Objection 2 : Further, all are bound to the observance of the commandments, since this is necessary for salvation. Therefore, if the perfection of the Christian life consists in observing the commandments, it follows that perfection is necessary for salvation, and that all are bound thereto; and this is evidently false.
Objection 3 : Further, the perfection of the Christian life is gauged according to charity, as stated above (Article [1]). Now the perfection of charity, seemingly, does not consist in the observance of the commandments, since the perfection of charity is preceded both by its increase and by its beginning, as Augustine says (Super Canonic. Joan. Tract. ix). But the beginning of charity cannot precede the observance of the commandments, since according to Jn. 14:23, "If any one love Me, he will keep My word." Therefore the perfection of life regards not the commandments but the counsels.
