Why Did Rome Kill Christians?
Rome killed Christians for refusing to worship its gods, but the courage of the martyrs, and the Church's mercy to those who failed, made the Church grow.

What this lesson teaches
- Rome persecuted Christians because they refused to worship the state gods and the emperor.
- Persecution came in waves, the worst under Decius, Valerian and Diocletian.
- Martyrs numbered in the thousands, and the Church chose mercy for those who lapsed and repented.
- Martyrdom is the supreme witness to the faith, and it still happens today.
