Romans 13 says to submit to authorities, not to join them in breaking Christ's teachings. Yes, God has given them the power to use the sword, and if we commit crime we should expect to be punished by the sword.(Quote)
Romans 13 goes on to say that "Governments are God servants. Avenging Angels placed upon theis Earth to bring wrath upon evil doers" So, this is God work that only unbelievers should be allowed to do? If you are doing the job of briningin wrath to evil doers, you are not breaking Christs teaching. When Soldiers asked John the Baptist "What shall we do?" John did not command them to shed thier uniformas and desert the Army, He told them to collect no more tax than commanded and to be content with their wages. In summary, he commanded them to do their job fairly and justly in a manner pleasing to God. To only put the evil to the sword and not the innocent. Not to abuse thier authority but use it to serve. Roman Soldiers were allowed to plunder the populace for personal supliment to thier pay. When John commanded "Be content with your wages, he ordered them not to exercise thier right to do this but to live off of thier wage. (A tall order since soldiers were not paid well)
When a Centurian approached Jesus asking his servant to be healed, Jesus did not command him to resign from the military. He commended him as showing more faith than any Jew. Cornelius was another Roman Centurian who helped the Apostles. Once again, he was not commanded to resign from the Legion either.
