“After being redirected twice, Paul was at a standstill in Troas, on the eastern coast of the Aegean Sea. There Paul received the Macedonian Call: “During the night Paul had a vision of a man of Macedonia standing and begging him, ‘Come over to Macedonia and help us’” (Acts 16:9). This vision was the clear direction they needed. “After Paul had seen the vision, we got ready at once to leave for Macedonia, concluding that God had called us to preach the gospel to them” (Acts 16:10).
So, the geographical region of Macedonia became the first land to be Christianized on the European soil, and the region of Macedonia became the cradle of European Christianity. On this journey, St. Paul was accompanied by Silas, Timothy, and Luke the doctor, Evangelist, and writer of "Acts of the Apostles”.
