Alternative or variant form of partnership/sharing concept. Used in 2 Corinthians 6:14 for the incompatibility between righteousness and lawlessness.
The apostle asks what partnership righteousness can have with wickedness (2 Corinthians 6:14). The implied answer — none — establishes a principle of spiritual separation that governs all Christian relationships and alliances. This does not mean isolation from unbelievers (1 Corinthians 5:10) but refusal to yoke oneself in binding partnerships that compromise one's allegiance to Christ.
