No. I can't believe after reading all that, that you came to that conclusion. It would seem that you had a pre-conceived notion that you sought to prove perhaps. What the Catechism is saying is that, you are free to interpret within the guidelines stated but that ultimately, the Church is the arbiter on matters of faith and morals. Now, why is this? When Jesus said, He would send the Holy Spirit who would guide unto all truth, to whom was he speaking? Just anybody? No, it was to the Apostles.
God speaks to all of us through the Holy Scriptures and we are free to read and allow God's written word to enlighten us. But no one can read and personally interpret scripture and determine doctrine from it. The scripture's themselves speak against this. We can already see the result of doing so. It's called Protestantism. And to date there are over 30,000 different denominations all claiming the bible as their sole and final rule of faith. Well, unless they're all reading different bibles, they're just interpreting the same bible for themselves in different ways...known as private judgement, which the Catholic Church rejects for legitimate reasons.
Does this help?
