Ironically...
You are using Sola Scriptura to make your point.
Do we need say more?
2 Peter 2:1 niv
But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought thembringing swift destruction on themselves."
Will these false teachers be popular?
2Many will follow their shameful ways and will bring the way of truth into disrepute."
Peter warned that false teachers would work their way into authority after he was gone. He said it would happen to those he was writing to! And, that it will be preferred by many over the truth.
Now? If we had nothing but someone's word that they are telling us the truth? And, no way to verify? Then God had left us helpless.
How do we remain
separated from a lie? Sanctified from what is false?
Jesus declared how it is to be done...
John 17:17 niv
"Sanctify them by the truth; your Word is truth."
It does not say, by "tradition."
And, again?
You are attempting to disprove Sola Scriptura, by utilizing Sola Scriptura! How strange!
