The subject is that you are in a conundrum you will not discuss. You'll discuss 2 + 2 = 4 is not in the Bible and is not relevant but will not touch this point. Guess I know why.
Sola scriptura and sola fide were Reformation made. The Reformers didn't want a clergy so they gave you the Book and said "It's all in here. Figure it out yourself." Now, 30,000 denominations later, you still continually splinter.
What you need frankly is a Pope! That is how Jesus designed His Church to begin with... You are welcome to join us anytime. We'd love to have you!
Francis X.
Statement: Sola Scriptura is not in the bible.
My point: Yes it is right there where I pointed out.
response: Change the subject to the source of the bible. Change the subject to irrelevant math problems.
Conclusion: The casual observer probably wonders why you are so offended by what the bible says and by people that read and believe it.
