Do you believe the Bereans were sola scriptura? I think you are in error if you think that Catholics are not capable of holding leaders to the truth. If you listen to CAF radio, it is clear that a great number of Catholics recognize errors and report them with frequency. There is a procedure to be followed if a teacher makes a mistake. Individuals teaching error is quite different than the Church teaching error, do you understand this?
So, you are saying that, where Catholics are consistent with your interpretations of scripture, we have the truth, and otherwise, it is error?
