Soyeong: Saints don't generally become saints by making claims, but by living a life marked by Christian behavior, which includes humility. I'm not a Catholic, but of the Catholics I've talked with on this topic, not one of them considers saints to be intermediaries between God and humans. That would actually be to go against what the Bible teaches.
Actually people easily pray specialized saints (including mary) to intercede for them, rather than bothering the big chief directly. Also, saints being all perfect, they're also humble (okay, one could argue that the all perfect god is slightly lacking in that department, but that's another debate), but that's not really the point : saints are generally not contemporary to their users (even if their construction and officialisation may sometimes be). So, they don't have to build up themselves their own cult to themselves. But they are sanctified and idealised by others, who define them as exemplary, holy, and worship-worthy. There again, it varies a lot with different trends of christianism, and in the space between the official word versus actual popular practices. But yeah, saints (more than angels) often serve as communication channel between the earthly world and heavens. Plus, of course, the fringe cases of synchretisms, where saints become the new clothes of old, christianized, entities.
McDon: Though I feel I'm slowly turning away from religion I'm afriad of becoming an Atheist for fear of becoming narrow-minded and cynical when it comes to life.
You shouldn't worry about that, narrow-mindedness is independant from these beliefs. Atheists would argue that atheism makes people more open-minded, as it frees them from some Infaillible Word of God, and allows them to rethink and renegociate any moral problem, in accordance with the evolution of society, knowledge, technology, etc. In practice, some believers go "God says so, therefor this is moral, whgo am I to question this", but many rather go "this is not fair, therefore God could not have meant this", and then argue theologically like an atheist would. And likewise, atheists can also construct secular dogmas, and follow them to the letter, refusing to question any sort of belief and to risk discarding any moral position in which they've already invested too much of themselves. It's two different forms of narrow-mindedness or open-mindedness, two different flavors, but all in all, the consequences are equivalent in the religious or secular versions.
There are other, more serious reasons to fear of becoming an atheist. Death becomes unbearable (in practice, I think no atheist manages to fully cope with this form of absolute separation), injustice is never compensated after death (which puts an immense strain of responsability on moral decisions, and make the unfair even more impossibly tragic), there is no way to negociate with sheer luck and randomness (again, other forms of superstition may help there), and as everything is to be constructed, no guideline and no course of action is definitely legitimised by some over-human spirit : we're all merely tinkering with our lives, planet and perception. But there again, many atheists find refuge in other forms of (secular) moral authorities - politics, etc.
Simply said : atheism is bleak, despaired, and extremely brutal on the mind. As an atheists, I consider gods as fictions, but I think that everybody seeks refuge to analogous fictions, more or less formalised, more or less endorsed. Religions offer a ready-made, collectively supported narrative. We atheists have to find other ways to not directly face what would swallow and shatter our minds. But there's an emptiness at the corner of our eyes that is always ready to leap at us and engulf us. I think this is the thing you should worry about. The rest (empathy, open-mindedness, curiosity, etc) is completely independant, and you'll find the same amount of sectarian fundamentalists on both sides...
