The Bible is complete, authoritative, and true.
So that means that it is the only thing?
“So that means that it (the Bible) is the only thing?”
Absolutely. Positively. Without a doubt.
“The Bible is complete, authoritative, and true.”
Again, this is not what Sola Scriptura says.
Scripture is the only *infallible* source.
It also contains all that is needed for salvation and Christian maturity.
The Scriptures themselves recognize the legitimate authority God gives to the leaders in a church and civilian magistrates. They are not unchangeable and infallible, as is God’s Word.
