BW: Yes, it most emphatically does teach those things.
If not, then "No", you don't believe the Bible.
It doesn't say that.
The primacy of Peter as head of the Apostles?
It definitely doesn't say that.
The ablilty of the Apostles and their successors to forgive sins in Jesus' name?
Not to send them to hell or save them from hell.
that the Church (not the Bible) is the pillar and foundation of truth? (Just for a few examples)
With many warnings about false teachers and false teachings, but no warnings about the bible being incomplete or untrustworthy or requiring a church to interpret it for you.
