Scripture tells us not to be unequally yoked with unbelievers.
14 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? 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.
17 Therefore go out from their midst,
and be separate from them, says the Lord,
and touch no unclean thing;
then 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.” ~~2 Corinthians 6:14-18 (ESV)
Most Christians understand that this passage applies to much more than marriage. Those of you who follow my Tuesday series on the Reformation undoubtedly know that I by no means embrace ecumenical alliances. Furthermore, when I examine suspected false teachers, I often include looking at their associations in determining the legitimately of their ministry (though wrong associations, in and of themselves, don’t necessarily mean that a teacher is an apostate). God unequivocally calls us to separate from those who reject the Lord Jesus Christ.
That separation, however, never requires animosity, nor does it mean that we can’t learn from those who believe differently than we do. A public discussion of our differences (and even points of similarity) needn’t indicate that we have comprised the Gospel. Such compromise can happen, admittedly, but it doesn’t always occur.
Sometimes, properly understanding what Catholics, Muslims, atheists or Jehovah’s Witnesses (just to name a few examples) actually believe helps us witness more effectively, especially if we demonstrate a willingness to listen. Not all of us have the temperament to engage in such conversations, I realize. I can do it in writing, but not face-to-face (I consider my inability to do so as one of my many character flaws). But all of us ought to recognize the value in honest, respectful dialogue with people who embrace false beliefs.
Respecting someone enough to let them articulate their beliefs shouldn’t result in other Christians accusing us of violating 2 Corinthians 6:14-18. I may not have the grace to dialogue with someone of another religion in person, but I see tremendous value in extending that kind of respect to someone. Particularly if I want them to consider the claims of the Gospel!
Open, respectful dialogue, even when planned by both parties in a public setting, may not be the wisest course of action. But neither is it sufficient reason to accuse a brother or sister of compromising the Gospel. Before seizing on an isolated incident, examine the broader scope of that person’s teaching and overall ministry. It could just be that, precisely by having that dialogue, that person will make his or her separation from the world abundantly clear.
