While the Bible does use the word “marry” and “marriage,” rather than add an eleventh commandment, “Thou shalt have a wedding,” there is a commandment not to commit adultery. And you begin to realize that if it’s a sin to sleep with someone who’s not your husband or wife, then there must be some formal process to identify where a marriage begins and when it ends. In a world without weddings or marriage, you’d never have adultery. Because the lines were never formally drawn, it would be impossible to nail down when you’d actually crossed them. I think church membership is a little bit like marriage.
