"God Himself is the proof of His existence".
That's the suckiest argument he could have ever used. He's pretty much saying God exists because God exists. There's so many things he could have said...
In my religion class, we were taught about various religions, not only christianity, and we had to investigate and whatnot, and once I was in a debate where I had to prove God's existence.
YES. I WAS SUPPOSED TO PROVE GOD'S EXISTENCE. xD The other team had it easy as hell, proving God doesn't exist is a lot easier. I still conjured up tons of proof. And epically enough, a lot of it wasn't from the Bible (this is the part where Xero would say I need the Bible to prove God's existence. Well whatever), but actually based on logical reasoning, based on the way the universe is, and based on scientific facts.
...It was weird.
We just reached a consensus that we can't prove whether God actually exists or not, but the fact I actually had somewhat convincing arguments was neat. I might write about them at another time.
Then again, Religion was mostly a way to raise your overall average score, and if you wanted you could just skip it.

Back to the topic, there's TONS of different Christian doctrines. Mostly because they can't agree on how to interpret the Bible, and other things. I think it would be better if we could all be just one big family of Christians united by the fact that we all believe in Christ and God. But oh well, now we have people arguing about who's the one who's right about how God should be praised. And that sucks.
So yeah. I dunno what else to say, I don't really feel like I can contribute much to this topic. I was raised and baptized Catholic, but never confirmed. For now, I believe in God in my own peculiar way, I guess. It's probably better than spinning a roulette to try and guess which religion is the true religion. I'm not sure.
I'm aware of all the bad things that have been done throughout history in the name of religion (not only christianity, btw). Like I had said in the Discussion Corner, religion has often been used as a way to control people. I guess that steers me away from organized religion a bit. I mean come on, mormons and Jehovah's witnesses drop by your house to convince you to join their religions! xD
So I dunno what to say to you Bogdan. Just that it sucks that you're not allowed to believe in what you want to believe.
