See my post 66. Refutes your claim.
It refutes nothing of the sort. Joseph having children from a previous marriage is completely consistent with the doctrine of perpetual virginity, and as I understand, it is the common belief among the Orthodox. I think it helps explain a lot myself.
If Tertullian is your only witness against the doctrine, and I’d have to check what he said, but whoopdeedoo. That’s ONE Church Father against all the rest. And remember, though he wrote works in Greek, he likely learned it as a second language through his education. He was a Latin from Africa—not an area of the Empire known for Greek speakers.
