Theodosius (correspondent of Isidore of Pelusium)

Theodosius is known only as a recipient of letters from Isidore of Pelusium, the ascetic exegete active in the Pelusium milieu of the eastern Nile Delta in the early-to-mid 5th century. The address honorifics attached to the name vary across the correspondence, naming a 'bishop,' a 'presbyter,' and a 'scholasticus' (legal advocate), so this record may in fact gather more than one man under a single name; the letters themselves do not resolve the ambiguity. The content is overwhelmingly that of a spiritual teacher writing to a clergyman: Isidore expounds the dignity and burdens of the priesthood and the right reasons for fleeing or accepting episcopal office, interprets scriptural passages (the Lord's Prayer, Christ weeping over Lazarus, the 'heart of flesh' of Ezekiel, 'Let your light shine'), and urges self-sufficiency against luxury and the opinion of the crowd. Beyond these letters Theodosius is otherwise unattested.
