I’d say that’s more than just blathering, I did learn a little bit more than I did know, so it is of some worth.

But do they have St. Ignatius’ treatises against the Gnostics? Or, for that matter, the Gnostic treatises against St. Ignatius?

Will,
Do you mean Irenaeus’s anti-Gnostic works? I’m not aware of anything by Ignatius. If you mean Irenaeus, go to Maureen’s site (Maria Lectrix). She’s almost finished recording that tome, too!
