And that means scripture is the only or sole authority how perhaps? Lets imagine the apostles believed passionately sola scriptura. They exceeded what was their scripture in the day by introducing doctrines, practices and beliefs which are not to be specifically found within scripture. But lets suppose the apostles were then a special case that they had the ability to be auhtorities themselves, that they knew once they were gone there would be the scripture and everything would fall under it okay. So why then did the apostles not leave us a canon? An endless source of debate between different Christians since our canons all differ, the early church was just as confused on this point as well.
How do we know we are to specifically gather on sunday? I mean why not any other day? How do we know how a service ought to be run? Should we take from the jewish worship texts and use their mode as Jesus certaintly would have? Should we just read the bible? We know the bible tells to gather but what do we do when we gather?
Sola scriptura tries to make sense of how rome introduced many innovations, neglecting the fact that the scripture tiself as a canon as something to be believed was not established by it being the highest authority and listing its own texts, but by apostolic tradition which is not in the bible itself. And that says something that the basis on which the bible is established, when it is neglected the books of the bible become just as impotent as the gnostic texts.
