Letter to Flora

Until the discovery of Gnostic works among the hidden cache at Nag Hammadi, few authentic Gnostic works survived. One has been the "Letter to Flora" from a Valentinian teacher, Ptolemy— who is also known from the writings of Irenaeus— to a woman named Flora. The letter itself is only known by its full inclusion in Epiphanius' "Panarion", an unsympathetic context. 
Content.
The "Letter to Flora" relates the Gnostic view of the Law of Moses, a rational explication of the proposition that "the whole Law is divided into three parts; we find in it the legislation of Moses, of the elders, and of God himself". 
The author of the "Letter" assumes that the Christian Savior was sent, not to destroy the Law, but to complete it. He divides the Law among three types: the pure legislation of God embodied in the Decalogue, the mixed legislation "laid down for vengeance" affected by the world-situation of its first hearers (the world being inherently evil to a Gnostic), and
Though making points of a decidedly dualistic nature, Ptolemy supports his readings from "sayings" texts or "logia": "We shall draw the proofs of what we say from the words of the Savior, which alone can lead us without error to the comprehension of reality." He quotes sayings of Jesus that can also be found in the gospels of Matthew and of John, and he quotes Paul.
Ptolemy states in the letter that, "this division of the law (that is, god's own law) was established neither by the perfect god, as we have taught, nor surely by the devil -which it would be wrong to say- then the establisher of this division is distinct from them. And he is the craftsman and maker of this universe or world and the things within it." This excerpt reflects Ptolemy's gnostic view that the god that created the world is not the Perfect God, but rather an inferior god who incorrectly believed that he was the one true God, which is what he is trying to convey to Flora.
Literary form.
Such a publicly circulated Epistle was a literary form, rather than an actual missive sent by a "Ptolemy" to a "Flora", though it preserves that fiction, as all epistles do. The Letter was the classical equivalent of the Renaissance and modern Essay format. The attack on Ptolemy by Irenaeus does not eliminate the possibility that the present letter ascribed to him was composed by Epiphanius, in the manner of composed speeches that ancient historians put into the mouths of their protagonists, as a succinct way to sum up the Gnostic views he was intent on demolishing.
