Romans is the first of the Epistles.
After the five Historical Books of the New Testament, the Bible continues with the Epistles. These are letters written to teach and instruct Christian doctrine. The first nine of the Epistles were written by Saint Paul, and the first is called Romans. It was written whilst Paul was in the Greek city of Corinth, around 56 AD, to the Christians in Rome, a place Paul had not yet visited. He writes to introduce himself and asks the people there to pray for him. In addition, Paul uses his letter to talk about righteousness which comes from God.
"Recompense to no man evil for evil. Provide things honest in the sight of all men. If it be possible, as much as lieth in you, live peaceably with all men. Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord. Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head. Be not overcome of evil, but overcome evil with good"
