The Divinely instituted teaching authority, the Church.
So the church has the exclusive ability to interpret scripture, but who has the authority to interpret the interpretations of the Church? You?
Of course you can interpret Scripture for yourself. However, we, as the Church, are to do it through the lenses of what we have been taught by the Church already. We don't reinvent the wheel or deny what has been taught as dogma before. If you question my interpretations of the Catechism, you are more than welcome. But please provide me with a counter point of view with appropriate citations from a Council or Papal declaration, rather than your broad accusation.

How about the inspired declarations of Peter, Paul, Jesus, Matthew, James, Jude, Mark, Luke. Do they count?
When the subsequent councils clearly contradict the inspired declarations of Paul and Peter and Jesus, who are we to follow?
