Rev. Joe: "Odes of Solomon"

But to spray paint them in the colors of the Gospels is a travesty of restoration which effectively buries what glimmer of meaning we might derive from these golden, subtle poems.

Count this in the non-Christian camp. Note how it is listed both in "early Jewish" and "early Christian" writings in that collection. A bit of modern musical accompaniment. A New New Testament cites it as part of "some Christ movement," but that doesn't make it non-Jewish.
