That is a good teaching on putting on the Breastplate of Righteousness for the Christian; and good teaching concerning spiritual immaturity and spiritual growth to maturity. In some circumstances in a church, where there could be a conflict, disagreeing, or divisiveness, one or more Christians may need to either change, need more spiritual growth, or the solution for a conflict to be resolved may be a person needs to attend or visit one or more other churches.
Christians are to work to be at peace with other Christians and non-Christians. Christians may not always be in agreement about everything in a church, but can try to be at peace with others. If there are conflicts that can't be resolved or differences, then a Christian may need to attend or visit other churches to leave a conflict and for peace.
The Bible teaches that Christians should serve God and try to live at peace with others.
