I will go against the crowd here, and say that Internet helps me with my faith. It gives me free access to the life and writings of saints. It gives me access to the original words of people like the pope, and lets me contrast them with the reporting often given in the media. It gives me a connexion to a community of Christian people. And it lets me realise that most of the counter arguments to religion are nothing new, and have been debunked by great minds centuries ago. I recently came across a site dedicated to Fatima that had me entirely revisit the (very low) standards I had for my own faith and life.
Information on the net about religion is a little like information on sex and love. Good luck trying to understand what true love is by going to porn sites! Same thing trying to understand what the true love of God is The first post I see here equates knowledge to the antichrist. It's funny, because it's typical of the derisive "information" you can find on the net, which combines some familiarity with basic concepts and utter ignorance of what's really behind them. Yes, the original sin derived from knowledge of good and evil. No, this does not mean at all that the catholic church condemns knowledge! A good lie has to be believable, and you know who the master of all lies is
I'm really sorry to hear that the original poster became an atheist by reading about religion on the Internet. He was already away from faith, since he said that he would have identified himself as religious without attending service (aka not really religious). If you don't attend service, chances are you did not personally meet God yet. For most christians, faith means a personal encounter of some sort. Trying to use internet arguments against my faith is a bit like trying to use porn as a proof that my wife's love is not real
