What does the Bible say about loving others despite differences?

The Apostle Paul emphasizes the importance of love and faith in Philemon 4-5, where he expresses gratitude for the love one has towards Christ and fellow believers. Such love embodies the Christian's response to others, as it extends beyond denominational lines to include all who sincerely love Jesus. While Christians are called to hold firmly to the truth of the gospel, this must be done with a heart open to dialogue and fellowship with those who may differ in less critical points of doctrine. This is reflective of the character described in the New Testament, where unity and charity among believers are paramount, and contempt for others is cautioned against.
