There are some who believe that 2 Corinthians 6:17 teaches to not touch unclean food as defined by the Mosaic dietary laws.
To see that its not saying to follow Mosaic dietary law, we have to look at the context of the text.
2 Corinthians 6:14-18
.14 Do not be bound together with unbelievers ; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness ? 15 Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever ? 16 Or what agreement has the temple of God with idols ? For we are the temple of the living God ; just as God said, “I WILL DWELL IN THEM AND WALK AMONG THEM; AND I WILL BE THEIR GOD, AND THEY SHALL BE MY PEOPLE. 17 “Therefore, COME OUT FROM THEIR MIDST AND BE SEPARATE,” says the Lord. “AND DO NOT TOUCH WHAT IS UNCLEAN ; And I will welcome you. 18 “And I will be a father to you, And you shall be sons and daughters to Me,” Says the Lord Almighty.
In context, the text is telling us righteousness should have nothing to do with rebellion, that we are to stay away from the unbeliever, from idols. We are to be sanctified. God is living among us and we are to act like it. The text stating “DO NOT TOUCH WHAT IS UNCLEAN” is not referring to food or anything other than what was mentioned in verse 16 – idols. The unbeliever mentioned in verse 15 relates to the idols mentioned in verse 16. We must be separate and not touch idols, not be unbelievers, but to be believers and indwelt by God.
So no, 2 Corinthians 6:17 does NOT teach that we are to not touch unclean food as defined by the Mosaic (dietary) Law.
