Yes, but evolution is a scientific theory. There is a difference, it takes time and evidence before you can call a theory a scientific theory. So, if something is a scientific theory it has evidence backing it, it isn’t blind faith. I do not believe everything science tells me, that would be foolish. Science has been proved wrong again and again. With every fail there is gain. Scientists have been narrowing down the possibilities for hundreds of years. I do not believe everything science tells me. (Science includes evolutionists, just thought I needed to broaden the category.)
Ah, but much of science is in fact taken on blind faith. There are often competing theories that each camp will fight to defend tooth and nail. That does not make them useless, or illogical. In part, science and religion share this one common goal - the search for the truth.
Annabea, I believe that much of what you are displaying is confusion. There is a huge difference between Catholicism and fundamentalist Christianity. Catholicism, like hard-core theoretical science accept that there are true mysteries in our universe, whereas fundamentalist believe that they know certain things absolutely. You are very young, at 12. Should you decided to study science formally at the university level you will find, absolutely, that the more you learn about anything, the more you realize how little we know.
In effect, the universe is truly unknowable. There are many technical reasons why this is so. For starters, until we have the means to study anything with infinite resolution, we can only theorize about what happens beyond a certain resolution.
You make a good point about science failing and making gains. The same is true for the Catholic faith. Despite some ugly history, if you look at our faith objectively, with real detailed knowledge, you will see that it has been self-correcting over the centuries. The many negative events in the churches history have real historical context based on things like politics, greed, and power. But none of those things have changed our fundamental beliefs (what we learned from the ministry of Jesus). So despite the favorite historical points of athiest, trying to convince themselves that science and religion are polar opposites, the truth is that there is no conflict between Catholicism and science. There might be conflict between fundamentalist beliefs and science, but not Catholicism. You’re really at the right place to question Christianity.
In truth, choosing to be agnostic about things (whether science or religion) might be comforting because it seems safe, but it will do little for your soul. For the most part, Catholics are primary concerned with the ministry of Jesus. Jesus added to the commandments by saying that we must love our brothers as we love our selves. 1 Corinthians 13 tells us that love is the greatest gift of all, and somewhat instructs us that the goal is to perfect love. As God, Jesus said, as we treat the lessor of our brother, we treat Him.
With regards to your statistics, it’s a good example of how people (not you) lie with statistics. Just because one calls (labels) themselves a “Christian” doesn’t make it so. The name of religion is abused for convenience. Don’t forget this very important point. This is a whole topic of discussion in itself. Fundamentalist will say that belief in Jesus is enough. Catholics believe, (or should know) that while this is a necessary condition, it is NOT sufficient.
My only advice to you Annabea is that you not confuse fundamentalism with Catholicism, because they are very different. The Bible was not conjured up magically, but rather an effort of a body of people who put a lot of thought and prayer to the task of capturing the Word of God. There are good reasons why many books were not included in the canon. Some faiths are based in part on books that did not qualify. So yes, there are real differences between faiths, but to understand those reason will require a fair amount of study.
If your point is purely to debate, then you will accomplish little in terms of understanding our (Catholic) Christian faith. If your point is to understand our faith, then you’ll have to do a lot of your own research. This is a good place to be. Be respectful in your quest, and the path will be much more fruitful.
