We're all comrades in Christ, equal before God, according to the Bible

nope

Don't just say "nope," give me reasoning.

This is not even close to accurate.
Equal at birth, equal if you repent and accept Jesus as your lord and Saviour.
Results for anyone outside of that may vary, to say the least

That's only page one of the book titled 'what are you on about?'

Everyone who goes to hell is equally punished, and everyone who accepts the lord is equally rewarded. What's the problem here, eh?

What reasoning? Don't just say that it sucks and walk away, tell me why. Don't just say it doesn't make sense, tell me why it doesn't make sense.

I mean, think about it. The entire system of Communism was designed to support and maximize the unity and "happiness" of its people.
There are a couple things in the Bible that might suggest that a sharing system is good, for example Acts 4:32: "All the believers were one in heart and mind. No one claimed that any of their possessions was their own, but they shared everything they had." I'm willing to argue that this means that communism could work.

Though, there is one problem you may notice. Communism has never worked! That is very true. Though it's always been caught up at socialism, where rulers are supposed to force redistribute stuff (and that will never work on multiple layers, so I argue Communism away from the socialist process), I don't think it would work even if the forced redistribution worked, so clearly Communism is missing something. But what?

Love. That's what. Love is very clearly pointed out in the Bible as the most important, and my view of morality is a situational ethics view based completely on love, and 1 Corinthians 13:4-7 points out those desirable traits you'll have if you have love.

So what does love have to do with Communism? Well I would argue that if everyone had this amazing thing called love, then we wouldn't need a money system, everything could just be like what Acts 4:32 is.

This brings me to a very important point. Socialism. I think that this phase, when becoming a communist utopia, will not help anybody. Distribution can't be forced in that way, and certainly not by a corruptible leader named Joseph Stalin. So, this love utopia can only happen naturally. If everyone really did have this love, then over time, people will start making kind donations to each other and stop using money. The worker's utopia cannot work if people don't care, but if people care in a method called love, the system would be perfect.

Now the only problem is getting everybody to have this love...

And please, if anybody has a good contradictory idea that goes against mine, I strongly encourage them to present it.
