“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.
that came from you, not me!
