Catholic Dictionary




A declaration telling God or another person that one will or will not do something. A promise made to God is equivalently a vow, and it binds in conscience according to the gravity of the promise and the intention to obligate oneself under pain of sin. Promises made to people must be kept, and they oblige in justice or charity, with more or less seriousness depending on one's ability to fulfill a promise and the harm caused to another by not keeping one's word.
