Pretty much no. The last known Cathar perfectus in the Languedoc, Guillaume Bélibaste, was executed in the autumn of 1321. So by five years later, the Catholic Church could pretty much say that it had hunted down, slaughtered and burned alive every last man, woman and child who believed in Christ outside of the Church.
So yeah, you're right.
and these people learned of Christ, other than through the Catholic Church......how??? there was no other source of Christian knowledge and teaching than the Catholic church...
You think the Cathars were Christians?
Really?
