Luke’s Acts of the Apostles is an account of some of the pivotal moments in the Church’s earliest history. Historical records give us good reason to believe all of the early apostles, with the exception of John, died a violent martyr’s death. They kept the faith unaltered, despite being widely scattered and seperated for years. The churches they founded continued in the Faith, and in some cases continue to this day. This is the amazing testament of the first century of Christianity. These early churches were not wholly independent congregations. The historical record shows that the early Church was indeed a catholic (universal) Church held by moral authority and a desire for unity.
Jerusalem and Rome appear as the two central cities for the early Church. Great trials and tribulations faced Christians in both cities including Nero’s attempt to blame the great fire of Rome on the Christians. In spite of the difficulties, Christianity continued to spread. Early pastoral letters of Ignatius and Polycarp provide additional extra-Biblical evidence for the early Church’s unity and fidelity.
