Letter 371

Isidore of PelusiumPansophius|isidore pelusium
From: Isidore of Pelusium, monk
To: Pansophius
Date: ~410 AD
Context: Isidore exposes the textual corruptions in the Marcionite version of the Gospel.

If the advocate of Marcion's blasphemy puts forward their so-called Gospel, take it up and read it — you will find the absurdity right in the opening pages. They have cut out the genealogy that traces Christ's descent from David and Abraham [Matthew 1:1-17]. And proceeding a little further, you will see another piece of malice. They altered the Lord's own words — where he says "I did not come to abolish the law or the prophets" [Matthew 5:17] — and made it read: "Do you think I came to fulfill the law or the prophets? I came to abolish, not to fulfill." From this you can see how they manufacture hostility between the two Testaments, fabricating the claim that Christ is a stranger to the law. This is what heretics always do: they do not invent new scriptures from scratch — they mutilate the real ones. A half-truth is more dangerous than a whole lie.
