So what? What might happen if we went back to the way they did things in the Bible? Should we? Let me muse about this matter.
1) One disturbing trend is the number of young people who are living together, having children, but not marrying. I believe that one reason for an increase in such couples is economic. Weddings cost too much. They don't have to, of course, but they often do. So the couple decides to live together without marriage. Years ago, in the church I attend, a couple got married after the morning service. The pastor just said, to the congregation, something like, "You are dismissed. However, if you wish, you can stay for the wedding of X and Y, who will be undergoing their marriage ceremony right after the service." Most of us stayed. Some people were there for the ceremony, who wouldn't have been there otherwise. The pastor performed a simple marriage ceremony, and that was it. No big reception. No invitations. No florist. No photographer. The couple are now grandparents, and are still married. I don't know if they are part of a church now. The last I knew, they were. (My wife and I eloped, also getting married without any of the expensive trappings.)
(However, it seems that marriage ceremonies in Israel were also expensive, or at least often were, perhaps lasting several days, and requiring an abundance of food, and other preparations. See here for an article on marriage ceremonies in Bible times.)
I suggest that church wedding ceremonies should be short and simple. That way, people who want to marry and live together could do so, with the blessing of a church, without burdensome expense for the parents and themselves. Anyone who wants to could have a big party, with catered food, flowers, music, and photographer, but let that be separate from the church ceremony.
2) Consider how little time is spent on the religious part of getting married, compared to all the rest of it, in a "church wedding." The actual ceremony, conducted by a minister, is often considerably shorter than the time the guests have to wait for the family photographs to be taken. Throw in the showers, the rehearsal party, the reception, and other events, and the formal wedding ceremony, itself, becomes insignificant -- a minor appendage on a big event.
3) Churches, or pastors, or parents, often seem to hope that, if an unchurched couple is married in church, they will decide to become part of that church body. Perhaps that happens once in a while. I don't think it happens very often. In some respects, having an explicitly Christian ceremony for non-Christians seems like hypocrisy. On balance, wouldn't it better for churches and pastors to not encourage non-churched couples to get married in church, but rather to discourage it?
C. S. Lewis (who had never been married at the time) said this:
A great many people seem to think that if you are a Christian yourself you should try to make divorce difficult for every one. I do not think that. At least I know I should be very angry if the Mohammedans tried to prevent the rest of us from drinking wine. My own view is that the Churches should frankly recognise that the majority of the British people are not Christians and, therefore, cannot be expected to live Christian lives. There ought to be two distinct kinds of marriage: one governed by the State with rules enforced on all citizens, the other governed by the Church with rules enforced by her on her own members. The distinction ought to be quite sharp, so that a man knows which couples are married in a Christian sense and which are not. both quotes from "Christian Marriage," pp. 96-103, in Mere Christianity.
