In attacking the Catholic Church, you quoted Caiaphas. That makes me feel like I'm on the right side. That's what I said. What is this "determining what things mean" stuff?
You found the Scripture perspicuous in that Caiaphas said it, you judged that he really meant ill, and concluded that he was a malefactor. These are matters that were clear to you.
Why then are you not at liberty in Catholicism to interpret all of Scripture for yourself?
