Longinus of Nubia

Longinus was the priest who celebrated the Eucharist for the aged patriarch Theodosius of Alexandria in his exile (John of Ephesus, Ecclesiastical History 3.4.5, as summarised by the translator). John of Ephesus, who is the only source cited here for his life and who took his side, says that he was consecrated bishop for the Nobadae when Theodosius died, was denounced to the emperor as an enemy of the palace and detained for three years, and escaped wearing a wig, since he was bald. Among the Nobadae he taught, built a church and ordained clergy (John of Ephesus, Ecclesiastical History 3.4.8).

After five or six years he was called to Egypt to consecrate a patriarch for Alexandria, an act that John says brought schism on the whole church of his party (John of Ephesus, Ecclesiastical History 3.4.9). The Alexandrians declared him deposed. The king of the Alodaei nevertheless asked for him, and John quotes his letter describing the journey, on which he lost seventeen camels, and the baptism of the king and his nobles, which John dates to the year 891 of the Greeks, that is 579–580 (John of Ephesus, Ecclesiastical History 3.4.49–53).
