That isn't remotely the "Catholic/Lutheran/Anglican model".
A more correct understanding would be "what is required is what the church has always done and believed, whether or not that requirement is directly found on the surface of Scripture".
By contrast, just doing any old thing is innovation, which is the fast route to heresy.
That isn't remotely the "Catholic/Lutheran/Anglican model".
Sorry, I should have added "based on the authority of the church."
