Eastern Orthodoxy by country
Based on the numbers of adherents, the Eastern Orthodox Church (also known as Eastern Orthodoxy) is the second largest Christian communion in the world after the Roman Catholic Church. The most common estimates of the number of Eastern Orthodox Christians worldwide is approximately 200–260 million. The numerous Protestant groups in the world, if taken all together, outnumber the Eastern Orthodox, but they differ theologically and do not form a single communion.
Apostasy in Islam
Muslims constitute approximately 36.5–37% to 48–50% of the Eritrean population; more than 99% of Eritrean Muslims are Sunnis. Although there are no legal restrictions on leaving Sunni Islam, there are only three other officially recognised religions in Eritrea, all of them Christian: the Eritrean Orthodox Tewahedo Church, the Eritrean Catholic Church (in full communion with the Roman Catholic Church) and the Evangelical Lutheran Church of Eritrea. Despite other religious groups applying for original recognition since 2002, the Eritrean government has failed to implement the relevant rights established in the constitution. It is illegal or unrecognised to identify as an atheist or as non-religious, and illegal to register an explicitly humanist, atheist, secularist or other non-religious NGO or other human rights organisation, or such groups are persecuted by authorities. Members of “unrecognised” religions are arrested, detained in oppressive conditions, and there have been reports that people have been tortured in order for them to recant their religious affiliation. Reports of the harassment and arrest of members of religious minority groups is widespread and frequent. Open Doors reported that Muslims who become Christians in Muslim-majority areas are frequently rejected, mistreated or even disowned by their families. Additionally, the Orthodox Church considers itself the only true Christian denomination in the country and puts its ex-members who convert to a Protestant faith under pressure to return.
