Whether a vow is solemnized by the reception of holy orders, and by the profession of a certain rule?

Objections

Objection 1 : It would seem that a vow is not solemnized by the reception of holy orders and by the profession of a certain rule. As stated above (Article [1]), a vow is a promise made to God. Now external actions pertaining to solemnity seem to be directed, not to God, but to men. Therefore they are related to vows accidentally: and consequently a solemnization of this kind is not a proper circumstance of a vow.
Objection 2 : Further, whatever belongs to the condition of a thing, would seem to be applicable to all in which that thing is found. Now many things may be the subject of a vow, which have no connection either with holy orders, or to any particular rule: as when a man vows a pilgrimage, or something of the kind. Therefore the solemnization that takes place in the reception of holy orders or in the profession of a certain rule does not belong to the condition of a vow.
Objection 3 : Further, a solemn vow seems to be the same as a public vow. Now many other vows may be made in public besides that which is pronounced in receiving holy orders or in professing a certain rule; which latter, moreover, may be made in private. Therefore not only these vows are solemn.
