Various people on the Internet and even here on the BB have felt free to used insulting language towards some group of people or another and then claim that Christ did so, therefore Christians can and should. They’ll say something like, “Jesus called the Pharisees hypocrites, fools, blind, serpents and vipers (Matt. 23:13-33), so it’s perfectly okay to call Christians these or similar names (idiot, moron, etc.).” I completely disagree with this. It is not okay for believers to call people names based on what Jesus said. 1. Jesus was speaking to Pharisees—lost people. He never spoke to believers this way, or even to people who claimed to be following Him but were possibly not. 2. Jesus was speaking as Lord, not as an example to believers. (See the context at the end of Matt. 22.) He said many things we cannot or should not say, such as “I came not to judge the world but to save the world” (John 12:47). 3. Jesus was also speaking as the Founder of the Jewish faith, rebuking the current leaders of that faith who had taken the religion in a terrible direction. We are not the founders of the Christian faith and have no right to insult others who claim the name of Christ. 4. When the disciples of Jesus were harsh towards people not of their group but yet who claimed His name, He rebuked them (Luke 9:49-50). 5. The practice of insulting people is rebuked by Paul in several places, such as Eph. 4:31, Col. 3:8, 1 Tim. 6:4. The Greek word used by Paul is blasfemia, which is the root word for our English word “blasphemy,” but has a wider range of meaning than the English word in that it can mean insulting another human as opposed to blaspheming God. So insulting people is wrong. 6. Christ Himself forbade calling a brother in Christ "fool" or "idiot" (raca) in Matt. 5:22b--"Whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire." I’m positive there are many other relevant passages, but I’m going to stop here, because the point should be obvious.
