Peter calls Paul's writings Scripture.
Are you telling us Peter is wrong?
"But the Lord SAID unto him, (Ananias), GO THY WAY: FOR HE (Paul) IS A CHOSEN VESSEL UNTO ME, TO BEAR MY NAME BEFORE THE GENTILES, AND KINGS, AND THE CHILDREN OF ISRAEL: FOR I WILL SHEW HIM (Paul) HOW GREAT THINGS HE MUST SUFFER FOR MY NAME'S SAKE." Acts 9: 15,16.
These are Jesus Christ's own words concerning Paul. ( They are probably in red in your BIble). I'm sure He is not concerned about your opinion of Paul as much as He is concerned about the message He gave Paul to give you.
