Jeremiah Johnson of Grace to You asks: Should we or shouldn’t we debate our doctrinal differences?
Many believers argue that our focus should be on what we agree on, and that we must set aside anything we disagree on. So does that mean we should ignore our differences with those who teach universalism? What about those who teach the word-faith prosperity gospel…NAR/dominionist theology…Eastern mysticism…ignore these folks, too? Should we let slide sins such as fornication, adultery, homosexuality and abortion for the sake of unity?
Johnson argues that we must do as Paul instructs us in 2 Timothy 2:14 and hold fast to sound doctrine. He includes the following quote from Dr. John MacArthur:
Paul’s purpose was to motivate and encourage Timothy to keep a firm grasp on that truth himself and to pass it on to others who would do likewise … It is only with a thorough knowledge of God’s truth that falsehood and deceit can be recognized, resisted, and opposed. . . .
So back to the question at hand: Does God condemn debate? Let’s find out…
Almost twenty years ago, during Moody Bible Institute’s Founder’s Week conference, I heard Jim Cymbala make the following plea for unity:
Think of the division right now in the Body of Christ. We have all these names that don’t exist to God: Baptist, Presbyterian, Nazarene, Pentecostal, Charismatic. God doesn’t have any idea what any of them mean, because He only has one Body. . . . He has one Body—the Body of the Lord Jesus Christ. Evangelical—evangelical doesn’t even exist to God. We’re using words that aren’t in the Bible. We’re thumping the Bible and being unbiblical while we’re thumping it. He only has—there’s one Lord, one faith, one baptism, one Body. And He doesn’t like us dividing up His Body. 
In the moment, it struck me as nonsense. Of course God knows what our denominational titles mean; of course He understands where the doctrinal lines have been drawn in the sand.
But then again, who is going to argue in favor of division?
The church’s current fascination with the soft ecumenism of identifying and celebrating common ground hinges on a false dichotomy—that all division grieves God. They point to a variety of texts—frequently wrenched out of their original context—to make that point.
Cymbala’s text, for example, was Mark 3:20–26—a passage in which Christ answered the allegations that His power came from Satan. The Lord rightly points out it would be illogical to use Satan’s power to cast out demons—that “a house divided against itself, that house will not be able to stand.” Cymbala turned that statement into a rebuke to a divided church.
Today another text is frequently floated as a mandate for unity: “Remind them of these things, and solemnly charge them in the presence of God not to wrangle about words, which is useless and leads to the ruin of the hearers” (2 Timothy 2:14). Often, that’s taken to mean we should not debate our doctrinal differences—that we shouldn’t let doctrine divide us at all. If we say we’re Christians, we ought to focus on what we agree on, and set aside anything on which we don’t.
Under certain circumstances, that posture might be acceptable. But, as John MacArthur explains, in a world overrun with false gospels and false christs, we cannot afford to simply brush away every doctrinal line in the sand.
Through the centuries, the steady stream of falsehood has become a deeper, wider, and increasingly more destructive sea of ungodliness. False teaching about God, about Christ, about the Bible, and about spiritual reality is pandemic. The father of lies is working relentlessly to pervert and corrupt the saving and sanctifying truth of God’s written Word, the Bible, and of the living Word, His Son, Jesus Christ.
“Christian” cults abound today as never before, as does every type of false religion. Many Protestant denominations that once championed God’s inerrant Word and the saving gospel of Jesus Christ have turned to human philosophy and secular wisdom. In doing so, they have abandoned the central truths of biblical Christianity—including the Trinity, the deity of Christ, His substitutionary atonement, and salvation by grace alone. In rejecting God’s truth, they have come to condone and embrace countless evils—universalism, hedonism, psychology, self-salvation, fornication and adultery, homosexuality, abortion, and a host of other sins. The effects of ungodly teaching have been devastating and damning, not only for the members of those churches but for a countless number of the unsaved who have been confirmed in their ungodliness by false religion.
