“Nor can you read God’s word apparently.”
Which version? Which translation? What about the books that aren’t included in whatever version you’re using?
The bible is as much a construction of man as it is the word of God.
Then on what or whose authority do you get to determine who is and who is not a Christian?
You can't rob the authority of the Bible by calling it a construct of man and then use it as authority to establish any other authority on earth.
