ANSWER: No! Taking such an oath would not be wrong. In the Old Testament we find that the Jews were commanded to “swear” by the “Lord thy God” (Deuteronomy 6:13). However, it had become the practice of the Jews in the first century to profane the name of God by taking His name irreverently and in vain (Exodus 20:7) through the misuse of “oaths” often designed to shade or cover up the truth. It is to such oaths that these passages refer. That this is the case is made clear by James, “but let your yea be yea; and your nay, nay” (vs.12). The thrust of this passage teaches that Christians are to be known for their truthfulness rather than their need of taking frivolous oaths to support insignificant matters. That not all oaths are wrong is seen in the fact that the inspired apostle Paul often invoked them, e.g., Romans 1:9; Galatians 1:20. It is also significant that even God Himself “sware” (Hebrews 6:13-20). So, clearly,not all oaths are sinful.
