Analysis of information sources in references of the Wikipedia article "Religion in Egypt" in English language version.
The Coptic Orthodox Church is the main Christian Church in Egypt, where it has between 6 and 11 million members.
The Coptic Church was a missionary and aggressive body up to the 4th century, carrying its missions into Abyssinia and beyond, almost to the equator.
All communal Christian monasticism stems, either directly or indirectly, from the Egyptian example. [...] Egyptian Christians (Copts) had missionaries in northern Europe — Saint Moritz the Theban [...] was drafted into the Roman army and ended up preaching the Gospel in the Swiss Alps where a small town and monastery are named after him — and there is some indication, but no conclusive evidence, of a Coptic missionary movement even as far afield as Ireland [...].
Coptic Christians make up the majority of Egypt's roughly 9 million Christians. About 1 million more Coptic Christians are spread across Africa, Europe, the United Kingdom and the United States, according to the World Council of Churches.
Egypt has the Middle East's largest Orthodox population (an estimated 4 million Egyptians, or 5% of the population), mainly members of the Coptic Orthodox Church.
