2 Cor. 6:14-16 Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what Fellowship has light with darkness? 15 What accord has Christ with Belial [worthlessness, unprofitableness, i.e. Satan]? Or what portion does a believer share with an unbeliever? 16 What agreement has the temple of God with idols? For we are the temple of the living God; as God said, “I will make my dwelling among them and walk among them, and I will be their God, and they shall be my people.
Not much needs to be said about the passage. While some maintain that this “yoking” comes even in the realm of business, no one doubts that this “yoking” in the least speaks of marriage. The unbelieving partner is not one with Christ and is, therefore, an idolater. Paul’s description here is pretty black and white. He contrasts righteousness with lawlessness; light with darkness; Christ with Satan; believer with unbeliever; the temple of God with idols. This is not a minor issue. This concerns God’s holy institution of life-long marriage. The nature of the ones joined together, if unequally yoked, is fundamentally different. This joining together will harm the Christian spouse in that they cannot share the most important part of their lives with their partner. There will always be a hole and blank space in that relationship. No Christian should knowingly have a relationship with an unbeliever, much less marry one.
§4 Marriage Ought Not To Be Within The Degrees Of Consanguinity Or Affinity
- Marriage ought not to be within the degrees of consanguinity or affinity, forbidden in the Word; nor can such incestuous marriages ever be made lawful, by any law of man or consent of parties, so as those persons may live together as man and wife. 1
- Lev. 18:6-18; Amos 2:7; Mark 6:18; 1 Cor. 5:1
Marriage is to be between one man and one woman, but there are limits. It is not to be within the degrees of consanguinity, i.e., blood relatives or affinity, i.e., those related by marriage (step-brother, step-sister) as forbidden in the Word. Consanguinity defines the relationship through blood, affinity defines the relationship by marriage. The Mosaic law speaks about the degrees of consanguinity in Leviticus 18 and there are various limitations put there. Such a relationship would be incestuous and it will never be made lawful. It does not matter if a law of man would accept the validity of incestuous marriages, biblically speaking, these cannot be valid marriages. Even the consent of the parties involved does not matter. Therefore, they may not live together as man and wife since there is no valid marriage between them.
Incest is clearly forbidden from the law of Moses onward. Prior to Sinai, it was not forbidden, neither was it forbidden in the beginning, for otherwise, we could not have multiplied from one man and one woman. Therefore, it was necessary and it was not yet declared sinful until the giving of the law to Israel. See espe...
