Swearing oaths and vows are forbidden in scripture: 1. Christ and James condemned swearing oaths. (Matthew 5:33-37, James 5:12) 2. Our witness and testimony should be with a yea or nay. 3. An oath is not needed by an honest man, and does not make a dishonest man truthful. 4. The law allows us to affirm rather then swear when giving testimony or filling legal papers.
