Only every scripture is profitable because God inspired it that way = unique in all the earth = sola scripture is inspired by God so that all of it is profitable....
That means sola scriptura is a rule of the faith.
No, it doesn't.
You inserted your claim and self-approved it. That isn't logic, that's sophistry: assuming your argument is true and never 'showing your work,' just rephrasing yourself many different ways.
The text is quite explicit, God inspired scripture so that every verse of it is profitable for doctrine in order that the man of God be complete:
16 All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness,
17 that the man of God may be complete, thoroughly equipped for every good work. (2Ti 3:16-17 NKJ)
The ASV is considered very literal:
16 Every scripture inspired of God is also profitable for teaching, for reproof, for correction, for instruction which is in righteousness.
17 That the man of God may be complete, furnished completely unto every good work. (2Ti 3:16-1 ASV)
Every scripture; All scripture > Every verse in Scripture
"Inspired of God is also profitable for teaching" >every scripture God inspired is profitable for teaching
That the man of God may be complete > furnished completely unto every good work.
Verse 17 is literally "in order that", which makes this the conclusion of the premises in verse 16.
God inspired scripture to be profitable for doctrine IN ORDER THAT the man of God be complete.This rules out God inspired scripture for the man of God to be complete once he adds to God's Word, the liturgy of the Orthodox church.
No matter how hard I look, i can't find that idea in the text.
