The Book of Acts of the Apostles tells about the founding of the Church of Thessalonica by the Apostle Paul during his second missionary journey. This missionary trip represented an important milestone in the propagation of the gospel of our Lord; for the first time in the history of Christianity, the doctrine of the Kingdom of God, came into contact with the Greek culture and his ancient philosophy.
And it was probably in Greece where Paul had to make his greatest effort to expose Christianity to win converts no longer coming from Judaism but from paganism.
The Book of Acts of the Apostles explains that the conversion of the first Greeks to the Christian faith was extremely difficult, the apostle of the Gentiles, as was his custom until that moment, focused his work on the conversion of the Jews to the new faith by preaching in the synagogues.
The book of Acts tells how Paul had to hastily leave the city of Thessalonica due to the persecution of the enemies of the gospel. In any case, over time Paul was able to verify that the small community remained faithful, and thus from the city of Corinth, he was able to send the first epistle to the Thessalonians. In this epistle, Paul put these brave Christians as an example of faith and perseverance.
This is how the Book of Acts tells us how Paul arrived in Thessalonica and made the first converts to the faith:
"When Paul and his companions had passed through Amphipolis and Apollonia, they came to Thessalonica, where there was a Jewish synagogue. As was his custom, Paul went into the synagogue, and on three Sabbath days he reasoned with them from the Scriptures, explaining and providing that the Messiah had to suffer and rise from the dead. ´This Jesus I am proclaiming to you is the Messiah,´ he said. Some of the Jews were persuaded and joined Paul and Silas, as did a large number of God-fearing Greeks and quite a few prominent women" Acts 17:1-4
