Christianity and Buddhist reincarnation ...

[ding]

I was adjusting for you.

So do you think that Jesus' shit stank?

Depends upon his diet. Maybe you can ask Him.

So if he's the son of god, then god's shit would stink too?

Maybe you can ask Him if you can smell it.

Do people shit in heaven?

Do they need to shit in heaven?

The Cathares, a.k.a. Albigensians, were a cult with a dualistic theology, very far from Buddhist or Christian, though they espoused parts from the latter. They attracted adherents by contrast with a thoroughly corrupt religious organization with a monopoly on power.
Purgatory may serve as some kind of metaphor, but otherwise is totally fabricated.
The appearance of good and evil is not due to 'God', it is due to human perception. The trouble 'religions' have is when they talk about 'God' and 'bad things that happen to good people'. The concept of 'God' inculcated in their faithful is so limited that there is no allowance for saying that if 'God' is 'God', everything was created by and is part of 'God'. Thus, if the opposite of 'good', exists, 'God' must have created it, too. From there, it is impossible to argue out of the assumption that 'God' wants suffering. Teaching people that their concepts of 'God' cannot be anything more than symbolic is too esoteric for most souls. They worship an image, as expressly told not to do, because they have not been taught how to conceive of 'God' without diminishing 'God' to something similar to Santa Claus.

Okay, this is more explanatory. So if the omnipotent nature of God is removed, then we do get hell on earth. But this then leads to the rebirth cycles, so this supports the OP.
