We have shown gnosticism was alive and well into the 4th
century, what information is there that it died off? It didn't
die off anywhere else. Is that just an assumption on your part
or do you have something at hand to demonstrate that Gnosticism
(in whatever form) lingered past the 4th century? But in the 5th
century the Visigoths became the dominant authority in the
region, and while centered at Toulouse, controlled much of the
Iberian as well as southern Gaul. Alaric II as King of the
Visigoths was an Arian, but tolerant of both Catholics and
Gnostics. Tolerant of Catholics, yes. But do you have anything
at hand to demonstrate the idea that Alaric was tolerant of
Gnostics? Or that there were Gnostics in significant numbers in
the Visigoth's kingdom to tolerate? after 508 most of the Gallic
holdings were lost to the Franks (Merovingians), and although
Clovis did convert to Catholicism, the Merovingians did allow
Gnosticism and Arianism to flourish. Highly doubtful. What's
your source for that statement? Eve
