Do you see this as a doctrinal issue?I can't find Christian ministers solemnizing weddings in the Bible. In the Old Testament, I can't find priests doing it either. Boaz got some elders involved on time, and that was also a land deal and they served as witnesses. In the Old Testament, it seems to have been an arrangement between the father of the bride, the bride, the groom, possibly the parents of the groom. The larger community would have been involved in the party. It seems as if the Roman pagan wedding got Christianized, and within several hundred years, it came to be seen as a requirement for a priest to perform a wedding ceremony. Now there are Protestant pastors who think they have the power to 'bind together' because the verse 'what God has bound together let no man put assunder' gets quoted in some wedding ceremonies.For me a doctrinal issue that relates to the Bible would be if the bride's father does not agree to the wedding to give her in marriage. The New Testament also mentions giving in marriage. Yet some Christians do not care about that, but only consider a wedding legitimate if there is the extra-biblical traditional element of an ordained minister performing the ceremony
