There’s no risk in believing the Holy Bible alone.
“All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works.” (2 Timothy 3:16-17, KJV)
It’s not prideful to defend against unbiblical doctrines with the Holy Bible.
Isolating oneself from the corruption that has just about taken hold of everything in the world is no vice.
I’m not self sufficient. I trust in the Holy Bible and God.
I trust only God’s words contained in the Holy Bible.
