The Coptic Church of Egypt is the earliest Christian church in the world, going back to around 42 AD. According to Bishop Eusebius of Caesarea, as well as Coptic traditions, Saint Mark the evangelist, who wrote the earliest of the four New Testament gospels, was the founder and first bishop of the Church of Alexandria, even before the Church of Rome was established. In his landmark History of the Church, written in Greek about the year 310, Eusebius writes: “Now, they say that this Mark was the first to have set out to Egypt to preach the gospel, which he had already written down, and the first to have organized churches in Alexandria itself “(Eusebius, HE 2.16.1). This information is supplemented by Eusebius’s Chronicle, where he places Mark’s arrival in Alexandria in the third year of Claudius’ reign, which would be AD 41-42 or 43-44. This is no more than ten years after the date fixed for the death of Jesus, traditionally held to be in AD 33.
