It is unfortunate when Christians can't get along or even have anything to do with one another. Not only does this harm our witness to an unbelieving world, but it turns us away for God's priorities for us. Shortly before His death on the cross, Jesus prayed for unity among those who would come to believe in Him. When the world sees Christians fighting, they wonder if the Gospel is really true. Only Satan wins when sincere Christians reject one another.
Do what you can to live at peace with your fellow believers- and join your Lord in praying for the unity of Christ's people, so "that the world may believe"( John 17:21).
" I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you loved me." _John 17:23
