The origins of the faith are deeply rooted in the life and teachings of Jesus. Historically, the term "Christian" was first used in the city of Antioch in Syria. Early followers were sometimes referred to as Nazarenes, a designation linked to Nazareth, the childhood home of Jesus.

The early spread of Christianity saw significant milestones in Eastern Europe and Central Eurasia. Armenia became one of the first states to officially adopt Christianity in 301 AD, followed by Georgia in 337 AD. Later, Bulgaria and Kyivan Rus also embraced the faith, establishing a long-standing Christian presence in the region.
