Atheists, tell me, a Roman Catholic: why should I become an atheist?

[Balaco]

Why does God allow the Bible to be so "unclear" at times?

"Unclear" may not be the best word to use in the title, but I didn't really know how to condense my thoughts. 

I know Christians/Catholics don't consider the Bible to have any contradictions, and regardless of whether this is true, why does God allow to Bible to seem like it could have contradictions? Why does God allow the Bible to be left up to so many interpretations that there's multiple denominations of the Christian faith? 

If the Bible is to be the infallible Word of God, why didn't God make it clearer?

These being Catholics, they explained how my questions work against sola scriptura. Most responders talked about how important the Church is to interpreting the faith. One explained how God's Divine Law is said to use both Scripture and Sacred Tradition to infallibly teach it.

Most responses I've gotten so far explained that God gave us the Church, only one Church, and other denominations are just considered to be due to human weakness. They say these other denominations have formed because they don't have the Church to interpret Scripture. I'd assume questions related to why God allows us weakness in this important aspect would be answered using free will as justification. This one Church was given by God before the Bible was written, and one person justified the variances within the Bible by explaining how the different authors had different perspectives and fields of knowledge.

I think this might be a good question to ask Protestants considering how different their responses would be.

So I ended up bringing these points over to Protestants. Some felt like God doesn't necessarily want them to understand certain verses before certain times, and feel like it's not a problem if they don't understand them until they get to Heaven. Some of these people brought up the matter of faith again....feeling that we ultimately need to trust in Jesus. 

One guy claims "God doesn't simply "allow" things to be unclear at times, but makes them unclear to outsiders". Not sure what he means by "outsiders"...I would imagine non-Christians, but I don't think that even makes sense. Doesn't this just make it harder for nonbelievers to follow the faith? I'll ask for elaboration.

Other responses generally claim that the Bible isn't 100% clear so that we can work through the challenges and become strengthened.
