This article starts with calling Tertullian the toughest and most uncompromising of the church fathers.
Well, if so, I wonder why he later converted to Montanism, which the catholic church then considered heretical..m
Yes, but he says he does not agree with Tetullian.
Since Tertullian insisted that the Holy Spirit was divulging no new doctrines, and since Montanus established the “office” of prophet to deal with local discipline questions, and since this infringed on the growing power of the bishops, perhaps the problem was less heretical than it was political. Maybe, who knows?
