_Tit. 1. Directions for the Right Making such Vows and Covenants._
[Sidenote: What a vow is.]
_Direct._ I. Understand the nature of a vow, and the use to which it is appointed.
A vow is a promise made to God. 1. It is not a bare assertion or negation. 2. It is not a mere pollicitation, or expression of the purpose or resolution of the mind: for he that saith or meaneth no more than, I am purposed or resolved to do this, may upon sufficient reason do the contrary; for he may change his mind and resolution, without any untruth or injury to any. 3. It is not a mere devoting of a thing to God for the present by actual resignation. For the present actual delivery of a thing to sacred uses is no promise for the future: though we usually join them both together, yet _devovere_ may be separated from _vovere_. 4. It must be therefore a promise, which is, a voluntary obliging ones self to another _de futuro_ for some good. 5. It is therefore implied that it be the act of a rational creature, and of one that in that act hath some competent use of reason, and not of a fool, or idiot, or mad-man, or a child that hath not reason for such an act, no nor of a brain-sick or melancholy person, who (though he be _cætera sanus_) is either delirant in that business, or is irresistibly borne down and necessitated by his disease to vow against the sober, deliberate conclusion of his reason at other times, having at the time of vowing, reason enough to strive against the act, but not self-government enough to restrain a passionate, melancholy vow. 6. Whereas some casuists make deliberation necessary, it must be understood that to the being of a vow so much deliberation is requisite as may make it a rational human act, it must be an act of reason; but for any further deliberation, it is necessary only to the well-being, and not to the being of a vow, and without it it is a rash vow, but not no vow.[47] 7. When we say, it must be a voluntary act, the meaning is not that it must be totally and absolutely voluntary, without any fear or threatening to induce us to it; but only that it be really voluntary, that is, an act of choice, by a free agent, that considering all things doth choose so to do. He that hath a sword set to his breast, and doth swear or vow to save his life, doth do it voluntarily, as choosing rather to do it than to die. Man having free-will, may choose rather to die, than vow, if he think best: his will may be moved by fear, but cannot be forced by any one, or any means whatsoever. 8. When I say that a vow is a promise, I imply that the matter of it is necessarily some real or supposed good; to be good, or to do good, or not to do evil. Evil may be the matter of an oath, but it is not properly a vow, if the matter be not supposed good. 9. It is a promise made to God, that we are now speaking of; whether the name of a vow belong to a promise made only to man, is a question _de nomine_, which we need not stop at.
[Sidenote: The sorts of vows.]
A vow is either a simple promise to God, or a promise bound with an oath or imprecation. Some would appropriate the name of a vow to this last sort only, (when men swear they will do this or that,) which indeed is the most formidable sort of vowing; but the true nature of a vow is found also in a simple self-obliging promise.
[Sidenote: The use of vows.]
The true reason and use of vows is but for the more certain and effectual performance of our duties: not to make new laws, and duties, and religions for us, but to drive on the backward, lingering soul to do its duty, and to break over difficulties and delays: that by strengthening our bonds, and setting the danger before our eyes, we may be excited to escape it.
