I am not on trial. What I believe about each of these is irrelevant. I am referring to the beliefs of others. But you continue to miss the point.
The conscience clause in the middle of the Catechism does allow for SOME disagreement with church teaching, if done after much effort and labor and discussion and reflection and prayer. One might, for example, disagree with the Church on contraception or divorce or capital punishment under such parameters. There is more gray area in the Catechism than one might think.
Why have a catechism, the Ten Commandments, or even a Catholic Church when there are gray areas that one is free to disagree with?
