"Christianity in Ethiopia dates to the 1st century AD, and this long tradition makes Ethiopia unique amongst sub-Saharan African countries. Christianity in this country is divided into several groups. The largest and oldest is the Ethiopian Orthodox Tewahedo Church (in Amharic: የኢትዮጵያ ኦርቶዶክስ ተዋሕዶ ቤተክርስትያን Yäityop'ya ortodoks täwahedo bétäkrestyan) is an Oriental Orthodox church inEthiopia that was part of the Coptic Orthodox Church until 1959, when it was granted its own Patriarch by Coptic Orthodox Pope of Alexandria and Patriarch of All Africa Cyril VI.
The only pre-colonial Christian church of Sub-Saharan Africa, the Ethiopian Church has a membership of between 40 and 45 million,[1] the majority of whom live in Ethiopia,[2] and is thus the largest of allOriental Orthodox churches. Next in size are the various Protestant congregations, who include 13.7 million Ethiopians. The largest Protestant group is the Ethiopian Evangelical Church Mekane Yesus, with about 5 million members. Roman Catholicism has been present in Ethiopia since the 16th century, and numbers 536,827 believers. In total, Christians make up about 60% of the total population of the country.[3] A 2015 study estimates 400,000 Muslims converted to Christianity in Ethiopia.[4]"

The story of Ezana’s conversion has been reconstructed from several existing documents, the ecclesiastical histories of Rufinus and Socrates Scholasticus...."

Eusebius of Caesaria, the first church historian, in his "Ecclesiastical History," further tells of how the eunuch returned to diffuse the Christian teachings in his native land shortly after the Resurrection and prior to the arrival of the Apostle Matthew.
"Before the Ethiopian king Ezana (whose kingdom was then called Aksum) embraced Christianity for himself and decreed it for his kingdom (c. 330 A.D.), his nation had already constituted a large number of Christians.
"During the persecutions of Diocletian (284-305 A.D.), commerce ports like Adulis, along the Red Sea, served as a sanctuary for Christians in exile, and the Christian faith began to grow rapidly in these areas. Pagans still comprised the religious majority at this time, but, as historian Kevin O’Mahoney argued, the Christian faith first took root in “the upper social classes and gradually spread downwards to become the religion of the people...”
