I am not Catholic, and do not follow Catholic beliefs, therefore the Pope and his opinions are no different to me than John Doe in the street.
I'm glad you try to let God's word be your guide. So do we all, if we are Christians. The problem is that God's word has to be discerned. The Bible is not a clear-cut set of teachings, in the way the Buddhist scriptures are, for example. Yes, there are clear-cut bits: the 10 commandments is one example; Christ's invitation (never forced, remember) to repent of our sins and turn to Him as the way to the loving Father is another example. Beyond that, much is open to interpretation. When you go beyond the essential gospel of Christ, and the 10 commandments, you are in grey areas and there are many questions that different interpreters answer differently.
Beyond those essentials, which all churches agree on (it is a nasty and pernicious myth that the Catholic church is a religion of works), we have a need for Spirit-guided interpretation. Over 1500 years, this interpretation was done within the Catholic church, with important checks and balances to make sure that what was taught was consistent with what came before. Then came the Reformation, and different men started teaching different things. Yes, the Catholic Church as an institution was corrupt and needed reform, but it did not need theological reform, and it was the utmost arrogance for the reformers to start changing doctrine. All church institutions need reform as all fall into the temptations of spiritual power.
Look at these forums. When a Biblical topic is discussed, it's "I believe it means ..." and "I disagree, I think it means ..." It is clear that it is NOT clear!
People disagree over infant baptism, the meaning of Revelation, all sorts of things. This is because the Bible can be darned hard to understand, beyond its core message of salvation in Christ. It requires hard, prayerful, scholarly work to understand, within a tradition of consistent interpretation. The Catholic Church offers that.
Jesus promised us the Holy Spirit, which would lead us into all truth. He promised us a Church, built upon the Rock that was Peter. Peter passed on this authority to his successors, right down to John Paul II.
