What’s Wrong with Living Together Unmarried?

A pastoral answer to a common question

That sounds a touch harsh, and it will need to be said in the context of a pastor who loves and cares; but it does need to be said to any professing Christian couple who really think it is moral to live together unmarried. For although they think they love one another, actually they do not love one another very much—and certainly not enough to make sex moral.

“So, can you show me from the Bible that it’s wrong for me to be living with my girlfriend?”

It comes to light that a Christian young man in your church is living with his girlfriend, unmarried. When you challenge him about this he responds with the question above. He is not aggressive, though perhaps a little defensive. But he really does seem to want to know the answer. He has not been a Christian long. All—or nearly all—his non-Christian peer group are living together, and really it hasn’t seriously occurred to him that it is wrong, let alone scandalous. So what is his pastor to say?

It will not do simply to show him New Testament texts forbidding ‘fornication’ (most English versions) or ‘sexual immorality’ (NIV), as he will quite reasonably ask how we know that these texts forbid faithful public living together unmarried. Actually I am sure the Greek word porneia translated ‘fornication’ or ‘sexual immorality’ does in general refer to all sexual intimacy outside marriage. But to demonstrate this is not a trivial matter.

“And after all,” our young man may say, “we are living as if man and wife, and the marriage certificate is ‘just a piece of paper.’ And there really doesn’t seem to be anything convincing in the Bible which makes a marriage ceremony essential. So what we are doing is morally responsible, and not at all like fornication or sexual immorality. I am not paying her for sex, as a man does with a prostitute. We are not breaking marriage vows by having an affair. We are not sneaking off for secret assignations in a covert and shameful way. On the contrary, we have quite openly moved in together. We love one another, and we are faithful to one another. So what’s wrong?”

It is important for we who are pastors to consider our answer. For this young man’s questions are not trivial. We are not saying he ought to marry because we are social conservatives who prefer the old way of doing things. We have no simple and convincing Bible proof text to quote. I myself doubt if there is an answer that can be condensed into a sound bite. But I want to suggest the lines along which our answer might run. Which are as follows:

1. Jesus taught clearly and forcefully that the sexual relationship of man and woman ought to be faithful and lifelong. We are not to separate what God has joined (Matthew 19:6; Mark 10:9). Any sexual relationship between a man and a woman that is not accompanied by the intention of lifelong faithfulness is, by definition, displeasing to God and immoral. It is not possible for a sexual relationship to be moral and intentionally transient. (It is essential to the definition of marriage that both parties pledge themselves to lifelong faithfulness; the fact that, sadly, some marriages later break does not change the fact that marriage is always built upon this pledge.) So there are two kinds of sexual relationships, ones that are built upon the pledge of lifelong faithfulness, and ones that are not.

2. There is a very great difference between public pledge and private assurances. This difference is not appreciated as it ought to be. In our privatized and individualistic culture we think there is little or no difference between private assurances exchanged between lovers on the sofa and public pledges made before witnesses (which is marriage).

But, in fact, there is a very great difference. A private assurance is, as we all sadly know, terribly easy to break. After all, when it comes to it, it is my word against hers/his as to what exactly was said. My reputation suffers minimal loss if I break a private word. BUT when I make a pledge before witnesses, I place my whole integrity and public reputation on the line. This is what happens in a marriage.
