Why is it necessary to address false doctrine in the church?

The importance of addressing false doctrine lies in the preservation of the purity of the gospel and the spiritual health of the church. Scripture warns us against false teachings and encourages discernment. In 2 Timothy 4:2, Paul instructs Timothy to preach the word, be prepared in season and out of season; correct, rebuke, and encourage—with great patience and careful instruction. This indicates that while it is necessary to confront false doctrine, our approach should be marked by patience and care rather than a combative or arrogant attitude. Moreover, we should aim to rather build up the body of Christ rather than tear it down through public accusations and witch hunts—a practice that has unfortunately become prevalent on social media platforms.
