There were Christians in Rome within a dozen or so years after the death of Jesus, though they were not the converts of the “Apostle of the Gentiles” (Romans 15:20). Paul had not yet visited them at the time he wrote his great letter in 57-58 A.D.
There was a large Jewish population in Rome. Probably as a result of controversy between Jews and Jewish Christians, the Emperor Claudius expelled all Jews from Rome in 49-50 A.D. Suetonius the historian says that the expulsion was due to disturbances in the city “caused by the certain Chrestus” [Christ]. Perhaps many came back after Claudius’s death in 54 A.D. Paul’s letter was addressed to a Church with members from Jewish and Gentile backgrounds.
In July of 64 A.D., more than half of Rome was destroyed by fire. Rumor blamed the tragedy on Nero, who wanted to enlarge his palace. He shifted the blame by accusing the Christians. According to the historian Tacitus, many Christians were put to death because of their “hatred of the human race.” Peter and Paul were probably among the victims.
Threatened by an army revolt and condemned to death by the senate, Nero committed suicide in 68 A.D. at the age of 31.
Wherever the Good News of Jesus was preached, it met the same opposition as Jesus did, and many of those who began to follow him shared his suffering and death. But no human force could stop the power of the Spirit unleashed upon the world. The blood of martyrs has always been, and will always be, the seed of Christians.
Pope Clement, in the early Church, third successor of St. Peter, writes: “It was through envy and jealousy that the greatest and most upright pillars of the Church were persecuted and struggled unto death.... First of all, Peter, who because of unreasonable jealousy suffered not merely once or twice but many times, and, having thus given his witness, went to the place of glory that he deserved. It was through jealousy and conflict that Paul showed the way to the prize for perseverance. He was put in chains seven times, sent into exile, and stoned; a herald both in the east and the west, he achieved a noble fame by his faith....”
“Around these men with their holy lives there are gathered a great throng of the elect, who, though victims of jealousy, gave us the finest example of endurance in the midst of many indignities and tortures. Through jealousy women were tormented, like Dirce or the daughters of Danaus, suffering terrible and unholy acts of violence. But they courageously finished the course of faith and despite their bodily weakness won a noble prize.”
