Titus 3:9-11 NLT
[9] Do not get involved in foolish discussions about spiritual pedigrees or in quarrels and fights about obedience to Jewish laws. These things are useless and a waste of time. [10] If people are causing divisions among you, give a first and second warning. After that, have nothing more to do with them. [11] For people like that have turned away from the truth, and their own sins condemn them.
As Paul prepares to conclude his letter to Titus, he reminds him to stay away from foolish discussions or disputes concerning genealogies or obedience to Jewish laws. Coupled with that reminder is a warning about people who cause divisions among the body of followers of Jesus.
In his ministry Paul had encountered people who argued about whether or not Gentiles had to follow the Mosaic law. There were disagreements over circumcision, eating food offered to idols, eating only vegetables, and observing Jewish holy days and festivals. The people in Corinth had even argued about which apostle they were following as their main teacher. These arguments had the potential to create divisions within the body of Christ.
Paul admonished Titus to avoid these type of arguments and the people who were starting them. People who felt it necessary to create disagreements among believers were to be warned one or two times. If they failed to stop the arguing, then Titus was to stay away from them. Paul had learned that contentious people would stray from the truth and simplicity of the gospel. He was trying to save Titus from becoming embroiled in the disagreements.
The type of people who create divisions because of claiming spiritual pedigrees and legalistic approaches to living as Christians are still around. They still cause divisions in the local body of Christ. And they still need to be quieted if at all possible. If they choose to continue to be argumentative in their dealings with other believers, then those who want to live in peace with other believers will simply have to do the same thing Paul told Titus to do—stay away from their influence because their errors will eventually condemn them.
