Sexual relationships and Jesus

Sermon on the mountWhat did Jesus say about sexual relationships? He spoke a great deal about the Kingdom of Heaven, about money, about hypocrisy, but not much very much about sex. He said nothing about homosexuality, abortion, masturbation, birth control or pre-marital sex, though to hear some fundamentalists speak, you would have thought he majored on these subjects.

What he did say relates mainly to divorce, adultery and marital unfaithfulness. Sexual immorality was mentioned once in a list, and lust was described as adultery of the heart. His message was that ‘sexual sins’ were harmful to human relationships and were therefore subject to the higher law, “love your neighbour as yourself”.

The Old Testament law has some more dos and don’ts but also says we should not eat pork and lobster! There is more said by Paul and others but that is beyond the scope of this article. I believe that we should read the rest of the Bible through the ‘lens’ of Jesus and so I am writing about what he said.

Divorce and unfaithfulness

On two occasions in Matthew’s gospel Jesus taught on the subject of divorce.

It has been said, ‘Anyone who divorces his wife must give her a certificate of divorce.’ But I tell you that anyone who divorces his wife, except for marital unfaithfulness, causes her to become an adulteress, and anyone who marries the divorced woman commits adultery. (Matthew 5:31-32)


Some Pharisees came to him to test him. They asked, “Is it lawful for a man to divorce his wife for any and every reason?”

“Haven’t you read,” he replied, “that at the beginning the Creator ‘made them male and female,’ and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’? So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”

“Why then,” they asked, “did Moses command that a man give his wife a certificate of divorce and send her away?”

Jesus replied, “Moses permitted you to divorce your wives because your hearts were hard. But it was not this way from the beginning. I tell you that anyone who divorces his wife, except for marital unfaithfulness, and marries another woman commits adultery.” (Matthew 19:3-9)

Jesus placed a very high value on human relationships. He said that marriage really is ’till death do us part’ and that breaking that relationship is harmful to both parties. He only allowed divorce if that relationship was already broken by sexual unfaithfulness.

In today’s world it is so easy to get a divorce, and statistics show that ‘Christian’ couples are not immune. Jesus’ high standards still apply. We should not be judgemental when we hear of a love-less or abused couple divorcing, but if we desire to follow Jesus we must take his words and high standards to heart and determine that nothing will come between us and our wife or husband.

Lust and adultery in the heart

You have heard that it was said, ‘You shall not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. (Matthew 5:27-28)

Lust is harmful, not directly in itself, but because it is harmful to the relationship with our wife (or husband). Lust can lead to unfaithful actions, but even if it does not lead to actions, the thought can cause us to be unfaithful in our minds to the one we love.

Lust is difficult to quantify. When does admiration of a beautiful body become lust? We are all guilty of unhelpful thoughts now and again. There must be some sort of sliding scale here.

I would say that once my thoughts say something like, “I would like to share a bed with her/him”, or “I bet she would be more proficient at love-making than my partner”, then I have clearly crossed the line and am unfaithful in my mind and in my heart.

Why did Jesus come over so strong on this. It was not to condemn us but because he knew how much God, his father, loved us, and wanted the best for us,

What Jesus did not talk about

There are a number of issues related to sex which have divided Christians but Jesus didn’t even mention them.

  • Homosexuality
  • Abortion
  • Masturbation
  • Birth Control
  • Pre-marital sex

I am not saying that these things do not matter, but clearly Jesus’ priorities are different. Perhaps I’ll be be brave enough to air some of them in future articles.

Love your neighbour as yourself

This, said Jesus, (along with loving God) was the most important commandment. Jesus’ teaching on sexual relationships was all related to this. Sex is good, but it has the potential to ruin human relationships. Jesus gave some very high standards of behaviour, but only in our own interests because he loves us.

  1. When Jesus saw religious authorities using their authority to oppress the poor, he called them a brood of vipers fit for hell.
    When he met the woman caught in adultery he told her to go home and don’t do it again.

    Too many in the church seem to got these two the wrong way round.

  2. Interesting thoughts, George. Jesus teachings suggest to me that we are unwise to build our moral foundations totally on the Bible, because it leaves a lot of matters without direction or with confusing direction (e.g. is divorce OK in case of adultery, or never OK?), and at the mercy of often self serving theological reasoning for these matters not mentioned by Jesus. We need to rely on the Holy Spirit, who will interpret the Bible to us, and teach us “right” responses on other moral issues. Thanks.


  3. George, to me, your last paragraph should be our focus. Love your neighbor as you would love yourself is the overarching theme. I do agree with your point that Jesus gives a very high standard on lust that no mortal person can meet, even the holiest of people. So, we should do our best, but we will be tempted and we will lust in our hearts, as we are so very human. I also like your points about what Jesus did not talk about, as in the US, we see too many use the bible as a weapon to demonize and exclude, which is when any religion is at its worst. If we heed what Jesus said, we will be inclusive, when religion is at its finest. Many thanks for writing this, BTG
