The story “Christianity: Out of Africa” in the Sept. 13 issue stated that with the exception of Egypt and Ethiopia, most of Catholic Christianity disappeared from the African continent with the rise of Islam in the seventh century. Eritrea and Sudan should have been included among the nations where Christianity survived. Christianity was not reintroduced to some African nations until the 16th century, but the four African churches listed have been in continuous existence since the earliest centuries of Christianity.
