Lesson 2: The Origins and Spread of Christianity

Key Idea

In 63 B.C.E., the Roman Empire conquered Judea, the ancient homeland of the Jewish people. Many Jews were unhappy living under foreign rule and wanted to govern themselves again. They longed for the return of their independent kingdom.

During this difficult time, many people found hope in their religious prophecies. These teachings promised that God would send a savior, known as the Messiah, to free them. This created a powerful sense of expectation as people watched and waited for a special leader to arrive.

Key Idea

In the Roman province of Judea, a Jewish teacher named Jesus of Nazareth gained many followers, especially among the poor. He taught a message of love for God and neighbor, offering hope in a time of hardship.

Jesus's growing popularity and his teachings about a coming "kingdom of God" made Roman and local leaders nervous. They feared he might inspire a rebellion against Roman rule.

Key Idea

After Jesus’s death, his apostles began spreading his teachings. While Peter was an important early leader, the apostle Paul was most responsible for the faith’s expansion across the Roman Empire.

Paul traveled widely and taught that non-Jews, also called Gentiles, could become Christians without following all Jewish laws. This was a revolutionary idea at the time.

Key Idea

At first, Roman leaders were suspicious of Christianity. Christians refused to worship the Roman gods, which was seen as an act of disloyalty to the empire. For this reason, many faced persecution and were punished for their beliefs.

This situation changed completely with Emperor Constantine. After winning a key battle that he credited to the Christian God, Constantine ended the official persecution of Christians in 313 C.E.
