Everything written in the Bible is God’s word, Scripture. No one can decide what is and isn’t Scripture. It is God’s word, not ours. They can choose to believe it or not, but the fact that it is HIS word never changes. So some people decide to add to or take away from God’s word to form a NEW doctrine, something that ISN’T in Scripture. Like, for example, Mary being sinless, or Mary’s bodily assumption into Heaven, Mary being the Queen of the Universe, or a Pope, etc. Those are clearly not Scriptural, in God’s word. Which is exactly why the Word of God is lost. And doctrines of fallen man are used to form religious systems. People rejecting God’s word. THAT is exactly what has happened.
“No one can decide what is and isn’t Scripture. It is God’s word, not ours. They can choose to believe it or not, but the fact that it is HIS word never changes. So some people decide to add to or take away from God’s word to form a NEW doctrine, something that ISN’T in Scripture.”
Then what did Martin Luther do? He tore out scripture that he disagreed with and founded his own church. Do you agree with his actions?
But the canon of the Bible was decided by the councils of the Catholic Church acting under the direction of the Holy Spirit. That very same organization of men, guided by the very same Holy Spirit is engaged in the defense and interpretation of the Bible under the guise of the Magisterium.
