i. A vow is a promise made to God about something which is good, possible, and better than its omission.

It is, then, a promise, a contract with God, a deliberate taking on one's self of a new obligation which binds the conscience; and in this it differs from a mere purpose to do better, which imposes no new and special obligation. Such an act must be perfectly human, performed with full knowledge and with complete use of reason, so that a vow taken by a man who was half drunk, or who had not the full use of reason, would not be valid. A vow, however, does not require actual and explicit consent when the obligation is assumed; it will be sufficient if there is virtual and implicit consent. A person who receives the subdiaconate, to which he knows that the Church has annexed a solemn vow of chastity, takes the vow by the very fact of being ordained, though at the time he is not thinking of it.

A vow in the [strict sense is an act of divine worship offered to God alone, and so we cannot take a vow to the Blessed Virgin Mary or to the saints.

The matter of a vow must, of course, be something which is lawful and good; it would be an insult to God to promise him to do something wrong. It must be something which is possible, both physically and morally, for there can be no obligation to do what is impossible. A vow, then, to avoid all sin, even the slightest, would be invalid, for without a special privilege of God it is impossible. The matter of a vow must not only be good, but better than its omission or its opposite. For what is promised to God in a special manner and under a fresh obligation must be something that will be pleasing to him, but a promise to do something which had better not be done cannot be pleasing to God, who desires our perfection.

A vow is absolute when it has no condition attached to it, otherwise it is conditional.

A personal vow makes a promise of some action to be performed; a real vow dedicates a thing to God.
