Sola scriptura is a doctrine held by protestants that basically says we only use scripture, not oral tradition or human only works. It is in some ways very biblical. Yet, we know the scriptures themselves contain historical proofs. These historical proofs are still prophetic in that a true prophet who is inspired is defining the history.
So, history and examples can still mean sola scripture. Realize Peter was sola scriptura long before protestants. Rome the congregation was sola scriptura in 175 AD. Catholics tend to hide these examples.
1 Peter 4:11
If any man speak, [let him speak] as the oracles of God; if any man minister, [let him do it] as of the ability which God giveth: that God in all things may be glorified through Jesus Christ, to whom be praise and dominion for ever and ever. Amen.Â
The churches' speech and sermons should be guided by the oracles of God. Thus, not man breathed but God breathed. This could be oral as a prophet, but oral prophecies were to cease so that scripture was left to us. Scripture is God breathed.
