Whether obedience belongs to religious perfection?

Objections

Objection 1 : It would seem that obedience does not belong to religious perfection. For those things seemingly belong to religious perfection, which are works of supererogation and are not binding upon all. But all are bound to obey their superiors, according to the saying of the Apostle (Heb. 13:17), "Obey your prelates, and be subject to them." Therefore it would seem that obedience does not belong to religious perfection.
Objection 2 : Further, obedience would seem to belong properly to those who have to be guided by the sense of others, and such persons are lacking in discernment. Now the Apostle says (Heb. 5:14) that "strong meat is for the perfect, for them who by custom have their senses exercised to the discerning of good and evil." Therefore it would seem that obedience does not belong to the state of the perfect.
Objection 3 : Further, if obedience were requisite for religious perfection, it would follow that it is befitting to all religious. But it is not becoming to all; since some religious lead a solitary life, and have no superior whom they obey. Again religious superiors apparently are not bound to obedience. Therefore obedience would seem not to pertain to religious perfection.
Objection 4 : Further, if the vow of obedience were requisite for religion, it would follow that religious are bound to obey their superiors in all things, just as they are bound to abstain from all venery by their vow of continence. But they are not bound to obey them in all things, as stated above (Question [104], Article [5]), when we were treating of the virtue of obedience. Therefore the vow of obedience is not requisite for religion.
Objection 5 : Further, those services are most acceptable to God which are done freely and not of necessity, according to 2 Cor. 9:7, "Not with sadness or of necessity." Now that which is done out of obedience is done of necessity of precept. Therefore those good works are more deserving of praise which are done of one's own accord. Therefore the vow of obedience is unbecoming to religion whereby men seek to attain to that which is better.
