Communion of Saints: Opposed to Communion with the Wicked
Source: TTT
2 Corinthians 6:14–17
Do not be unequally yoked with unbelievers. For what partnership can righteousness have with wickedness? Or what fellowship does light have with darkness? / What harmony is there between Christ and Belial? Or what does a believer have in common with an unbeliever? / What agreement can exist between the temple of God and idols? For we are the temple of the living God. As God has said: “I will dwell with them and walk among them, and I will be their God, and they will be My people.”
Ephesians 5:11
Have no fellowship with the fruitless deeds of darkness, but rather expose them.
