The constitution of Ethiopia ensures religious freedom for its citizens. According to the US Department of State, this is widely upheld through the observance of additional laws and policies.
Ethiopia was one of the first sub-Saharan African countries to adopt the Christian religion, and its practice dates back to the 1st Century AD. The Ethiopian Orthodox religion is the most widely practiced with 43.5% of the population identifying as such.
The Church of Ethiopia is one of the few Churches of Christendom where the worship of the primitive church has been preserved. This is largely due to the geographical position of Ethiopia and to the historical developments that led to her virtual isolation from the rest of the Christian world from the seventh century, as a result of which Ethiopia retained the form of worship she had received in the 4th century.
