Heraclides

Heraclides is known only as a correspondent of Isidore of Pelusium, who addressed at least five surviving letters to him in the early-to-mid-5th-century milieu of Pelusium and the eastern Nile Delta. Though the address-line of one letter calls him a presbyter, four of the five greet him as bishop, and Isidore writes to him as a fellow churchman seeking exegetical guidance: the letters answer scriptural questions about the high priest's breastpiece (the "logion," Exodus 28), Christ's charge to the apostles not to go "into the way of the Gentiles" (Matthew 10:5), and the chastening of Hezekiah's pride, alongside counsel on tempering discipline with pardon and on praising those who love virtue. The tenor is collegial rather than corrective: Isidore treats him as an interlocutor who poses thoughtful questions and to whom Isidore offers measured spiritual and interpretive instruction. Beyond these letters he is otherwise unattested, and no dates or biographical details can be established.
