According to the Bible an earring or a nose piercing means the loveliness of Christian submission. It is to be an outward adornment consistent with the the beautiful lifestyle of a gentle and quiet spirit which is most precious in the sight of God (1 Pet. 3:4). A Christian woman whose ears are pierced or has her nose pierced should do it for the blessing and honor of her parents or spouse. And it should be a true statement about her actual spiritual state. But as I replied to one friend, when you have immature or foolish college kids going out and getting nose piercings because it’s cool and edgy and all the pagan kids are doing it, what you end up with is basically a moral equivalent of Proverbs 11:22: “As a jewel of gold in a swine’s snout, so is a fair woman which is without discretion.” It doesn’t fit.
