Communism and Atheism

Is communism a name of party or is it just the opposite of capitalism? Is atheism an integral part of communism?

Well, to me communism is neither of those listed above. Its just a feeling like love, hate and desire. And more importantly, communism is in no way related to atheism. I strongly believe its possible for a core communist to have immense belief in God. In fact, when people realize there is a Super power above us, they are automatically overwhelmed by their feeling of humbleness and would treat the fellow beings on par with them, which I think is the essence of communism. There are many true communists in this country who are equally conscious of the presence of the Almighty. All religions preach people only to treat everybody as their own. But I wonder where the concept of atheism being an integral part of communism came into existence. Probably because the first breed of communist leaders were atheist. And people, greatly influenced by their principles, could have actually seen it to be a part of communism and could have accepted it. But then. What everybody does in the name of communism is only its diluted version with core values sacrificed and replaced by corruption.
