How do you reconcile Hebrews 13 with 1 Corinthians 7 on marriage?
The two passages fit together because Paul is not anti-marriage. In 1 Corinthians 7 he answers a question that it is not good to touch or embrace a woman enough to excite instincts, but he does not forbid marriage. Hebrews 13 affirms marriage is honorable and the marriage bed undefiled.
Les explains that Paul in 1 Corinthians 7 is answering a specific question, not declaring a prohibition on marriage. The issue was touching or embracing a woman enough to excite basic instincts, but Paul is not saying they cannot get married. Many people wrongly conclude Paul is anti-marriage, yet he is not. Les directs us back to Genesis, where God said marriage is for replenishing the earth, having children, and enjoying the relationship. Then in Hebrews 13, Paul does not utterly contradict his statement in 1 Corinthians 7; the two must be put together. Hebrews 13 says marriage is honorable in all, and the marriage bed is undefiled. Les also notes the contrast with Victorianism, which made sex a taboo subject except for childbearing.
Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.
Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman.
