The second of the Epistles, and the seventh book in the New Testament, is Paul's first letter to the Church in Corinth; I Corinthians. It was written when Paul was in the city of Ephesus, in modern-day Turkey, after he has heard about divisions in the Corinthian Church which he founded three years previously. There are reports of immoral behaviour and lawsuits between members, which Paul wishes to address. There are also questions concerning correct behaviour which Paul answers in his letter.
I Corinthians 7:32-34
"But I would have you without carefulness. He that is unmarried careth for the things that belong to the Lord, how he may please the Lord: but he that is married careth for the things that are of the world, how he may please his wife. There is difference also between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit: but she that is married careth for the things of the world, how she may please her husband"
