Whether it is requisite for religious perfection that poverty, continence, and obedience should come under a vow?

❌ Objection 1 : It would seem that it is not requisite for religious perfection that the three aforesaid, namely poverty, continence, and obedience, should come under a vow. For the school of perfection is founded on the principles laid down by our Lord. Now our Lord in formulating perfection (Mt. 19:21) said: "If thou wilt be perfect, go, sell all [Vulg.: 'what'] thou hast, and give to the poor," without any mention of a vow. Therefore it would seem that a vow is not necessary for the school of religion.

❌ Objection 2 : Further, a vow is a promise made to God, wherefore (Eccles. 5:3) the wise man after saying: "If thou hast vowed anything to God, defer not to pay it," adds at once, "for an unfaithful and foolish promise displeaseth Him." But when a thing is being actually given there is no need for a promise. Therefore it suffices for religious perfection that one keep poverty, continence, and obedience without. vowing them.

❌ Objection 3 : Further, Augustine says (Ad Pollent., de Adult. Conjug. i, 14): "The services we render are more pleasing when we might lawfully not render them, yet do so out of love." Now it is lawful not to render a service which we have not vowed, whereas it is unlawful if we have vowed to render it. Therefore seemingly it is more pleasing to God to keep poverty, continence, and obedience without a vow. Therefore a vow is not requisite for religious perfection.
