Letter 51

Isidore of PelusiumUnknown|isidore pelusium
From: Isidore of Pelusium, monk
To: An inquirer
Date: ~410 AD
Context: Isidore explains the meaning of Jacob's wrestling with God (Genesis 32).

The divine nature is unnameable. Yet Jacob asked the name of the one who wrestled with him and taught him to prevail over his passions through the touching of the sinew of his thigh. But he heard in reply: "Why do you ask my name?" [Genesis 32:29]. This was not the time — neither under the law nor before the law — for that name to be revealed. But late in the fullness of time, when human sins had multiplied beyond measure, "I will be called Jesus when I become human" — a name that means Savior. For it is for the salvation of sinners that I will undertake that great work of entering the world in flesh.
