You need not a pastor ,prophet ,elder or other ordained called person ?But the anointing which you have received from Him abides in you, and you do not need that anyone teach you; but as the same anointing teaches you concerning all things, and is true, and is not a lie, and just as it has taught you, you will abide in Him. 1 John 2:27
1 John 2:27 is scripture whether you believe it or not.
I'm hardly Catholic but I see a flaw in your argument as you argue that as I only need to listen .sometimes that voice isn't of God .God can work that way but why call and raise teachers when The Spirit works like that ?
I'm not called or inclined to teach .Im more of a oh look that roof is falling ,that church bus needs a driver ,I will attack that problem .give me a class yes I can speak and educate but it's not my purpose my desire.
The army ,that nco in me requires me to mentor and train ,but it's simply not a burning Desire that I love to .put a wrench in my hand ,a task and leave me alone or give me team I will go make it work .
My pastor is inclined to teach and mentor and guide .less so inclined to fix and my nature .
This is in part where mungo attacks you.i say that because while I disagree with him on the reformation it's true you are arguing I am my own pastor and teacher .
Sola scriptura isn't Solo me in the bible myself .it's others verifying that the bible does say it and it's that authority.
There are grey areas ,and protestants divide too much on silly stuff .
