Christians believe that marriage is for life. During a Christian wedding ceremony the bride and groom make promises before God to live faithfully with each other until death. Christians believe the husband and wife become 'one flesh' (The Bible, Genesis chapter 2 verse 24) when they get married, that God actually unites the couple in a spiritual way. This unity is expressed through sexual intercourse.

Divorce cannot be God's intention, as it is separating those that God has joined together and made one.

All Christians accept that divorce is wrong. However, Christian ethics is based on love and forgiveness. In the New Testament of the Bible, Jesus forgave people who had done wrong. Christians believe that they must forgive each other as Jesus forgave them when he died on the cross. Many Christians then, whilst not liking divorce, don't totally forbid it.
