Read Romans 16.
This closing chapter of the book of Romans was quite personal.
It began with Paul’s personal recommendation of Phoebe (vv. 1-2), then a long list of personal greetings (vv. 3-16). Just before his closing remarks, Paul warned the believers about “those who cause divisions and put obstacles in your way” (v. 17b). Those “divisions and obstacles” were “contrary to the teaching you have learned,” also according to verse 178.
Paul was concerned about false doctrine because that divides the body of Christ. Verse 18 told us that these false teachers would divide the church because of “their own appetites.” In other words, their doctrine was deliberately chosen and differentiated from the truth in order “to deceive the minds of naive people” (v. 18) for the personal profit of the false teachers.
Think about that long list of personal greetings in verses 3-16 and this warning in verses 17-19. Paul had seen many churches where there was once warm fellowship and strong friendships torn apart by false teachers. This entire letter was written to establish a doctrinal base, to teach the gospel Christ gave him to this church that had formed apart from Paul’s direct ministry. Paul wanted each person mentioned in this letter to fully understand the gospel, to believe it themselves and to welcome all–Jews and Gentiles alike–who believe it.
It would be a bad, sad thing, therefore, if “Ampliatus” (v. 8) pulled away from and stopped talking to “Rufus” (v. 13) because Ampliatus had departed from the gospel or because he had stopped accepting Jewish believers as genuine Christians or because he had broken fellowship over which day was the Sabbath and how that Sabbath was to be observed.
A proper understanding and acceptance of the gospel, a commitment to serve rather than be served, and an understanding that Christ has accepted many who don’t hold all the same convictions about everything should unify believers, not divide us.
For us, we should recognize that truth is something to be explored and that exploration involves questions and sometimes debate. But when God’s people know what they believe and why, it should unify us rather than divide us. When others come in with different teaching, we should examine their teaching carefully but also be suspicious about their motives.
Too many believers uncritically accept different teachings from some bestselling Christian author or TV personality or webpage they read. False teachers can be very persuasive; hold on to the gospel and reject everything that departs from it. The unity of Christ’s body is at stake.
