Like I said. Show me any other infallible source for what the apostles taught and you can disprove that scripture is the only source.
And, like I said, Sola Scriptura is impossible. It is not scripture only. You cannot put Holy Scripture in the dock and ask: On Christian doctrine, is Calvin right? Or Jacobus Arminius? Or is Cynical Bear?
There is no such thing as sola scriptura in practice.
You choose Scripture and yourself as the determiner of what it says, means and therefore right doctrine.
Not scriptural, and certainly a failing method for One Lord, One baptism, One faith.
Still have no other source than scripture ey?
