Thats the book where the woman who supposedly was supposed to have been burned for listening to Pauls teaching that all should stay virgins in order to get into heaven. While she is being readied for burning she sees the Lord in the likeness of Paul even though Jesus said they would not see Him again untill His coming at the end of time. Then when they lit the fire the ground opened up and hail and water came down and she wasnt burned. As you read the stories of Thecla the virgin in that book you can understand why Tertullian called it heretical.
It becomes obvious by the writings that by the year 200AD the pagan influences had begun to engrane themselves into the religion of those the CC calls church fathers.
I get the impression that you read that stuff as if it is scripture. Its pagan through and through as is much of the doctrine of the RCC.
I would not take Tertullian’s pronouncement as valid. He was declared, and died a Heretic.
Well, Tertullian wasn’t exactly orthodox throughout his career.
Maybe he became a good Protestant when he fell into the heresy of Montanism.
