Do the tenants of Christianity EVEN MAKE LOGICAL SENSE?

I'd be a-raisin' the rent, on them there TENANTS!

Yea, yea, yea... a simple slip up on a MoonDay... ;)

You mean love, forgiveness & the golden rule?
Yes, of course they make sense and if the world lived by them it would be a much better place.
Perfect? Of course not, but better? You bet.

No.

You thought "tenants" was the correct term.

Admit it, and assuage your guilt, and shame!

Actually, I knew it wasn't but figured it's GLP, who gives a shit, apparently YOU do... ;)

The tenants of Christianity should be evicted.

Christians got trolled hard for centuries lol.

Answering OP and haven't read subsequent posts.

Yep, the Christianity you're describing is fucking dumb. Thankfully, that's not all there is to Christianity. I'll be answering your points from the perspective (as well as I can) of Eastern Christianity.

(1) God punishes ALL humans based on the actions of the original pair? Would you condemn your grandkids and their granskids for the inequity of your children? Most parents would not.
- Yeah, this is totally crazy, which is why it didn't happen. Rather, Adam and Even contracted sin not as *guilt*, but as *death*. And death is an STD, pretty much. Bad deal, sure. But that's where Christ comes in as the New Adam: in Him we are freed from the ancestral sin.

(2) God destroys the world in a flood to cleanse the Earth? Would you burn down your house to get rid of a roach problem? Probably not.
- Pre-Deluge earth was really fucking horrible. We're talking planet destroyers and mass human sacrifice. Insanity. So maybe we really did deserve it. A roach problem? A biiiit more than that, methinks. Also, it's entirely possible we caused the Deluge to ourselves, and that God simply let it happen to us miserable fucks. Gotta' respect free will, and all.

(3) God requires a LAW of humans that NO BODY can fulfill - what human would mandate laws that no one could ever live up to, sounds like slavery to me.
- Only God can fulfill these laws... which he did (Jesus Christ)! So you're right, which is why we need to uncover the Image of God within us, and become deified: we need to become gods in order to be godlike. Tall order? Suppose so. Don't think God would settle for less, though.

Also, Divine Law is more like (e.g.) the law of gravity than (e.g.) United States federal law. It's a matter of metaphysical reality: to exist just means to follow these laws. Failure to meet these laws results in failure to exist. Pure logic.

(4) God sends his Son to die for humans, and resurrects him on the 3rd day. Does that not mean that the blood sacrifice (speaking of which why does "god" need a blood sacrifice?) of Jesus was null, if he was resurrected? Sort of like paying for something and then stealing your money back.
- Legalistic way of looking at it. It's like this: human beings are now subject to death, physical *and* spiritual. God can't stand that: He loves the little bastards too much. That is, He respects free will (otherwise, no Deluge), but in His love, He cannot allow them to annihilate themselves. So, to save humanity, He becomes human. He is therefore now subject to death. But He's also God, so He can't die. Death tries to take Him, but it can't. God kills death!

Also, Jesus could have died any other way and accomplished the same conquering of death. So why crucifixion? This will trivialize it, but in three words: theatrics for inspiration.

(5) The entire Bible makes absolutely NO SENSE. Its a book from primative men, and creative writers, for one purpose of unifying an Empire and creating spiritual slaves to passify civilization...
- The ascetic traditions testify against the purely political angle, though undoubtedly it's been abused for political purposes (and its supposed leaders have gotten too political for their britches). In terms of not making any sense, that depends on your presuppositions of what does and does not make sense. Until you're willing to cash that out, be careful (I mean this as admonition, not threat) where you go about slinging "makes sense" and "makes no sense."
