What geographical direction did Christianity primarily spread from Asia Minor?

Christianity primarily spread westward from Asia Minor, which is modern-day Turkey and the region surrounding it. This movement was significantly influenced by early Christian missionaries, particularly the Apostle Paul, who traveled throughout the Roman Empire, establishing churches and spreading the teachings of Christianity.

The Westward spread included regions such as Greece and Italy, helping to embed Christianity in the heart of the Roman Empire. Over time, this facilitated further expansion into Western Europe, leading to the establishment of various Christian communities and the eventual dominance of Christianity in those areas.

Northward, eastward, and southward movements did occur, but they were not as prominent in the early phases of Christianity's expansion compared to the westward momentum that significantly shaped the religion's early history and outreach.
