The presence of the Church in Sudan goes back to the 4th century
Christian Nubia

The notions are accessible and can be traced on the maps of a widely known handbook such as The History of the Church by Joseph Lortz or various maps, with correspondent comment, in Universal Atlas of the History of the Church edited by Hubert Jedin and others. Naturally it is sometimes difficult to locate such churches. But it is what has always happened, also in the West and in Europe. I remember a book by Father Jiry Vesely, of some years ago, on the evangelization of Cyril and Methodius among Moravians, Bulgarians and Czechs, entitled Writing on water. Even today one may happen to see “writing on water” done by an unknown African catechist, so that someone can be born again of water and the Spirit, which is the thing that counts.
