Hell and God cant Co-exist.

[SteveII]

Continual invention implies adding new things. I do not think that is the case. 

Couple of reasons some doctrines might have changed over the past 2000 years:

• Advances in philosophy in general and philosophy of religion specifically.
  
• Advances in natural theology and its importance.
  
• Advances in our understanding of the universe and our place in it. 
  
• Decentralization of theological thought. Now we have many more sects and denominations that bring out variations in thought and prompt reexamination of ideas.
  

There are some doctrines that cannot be changed lest Christianity ceases to be Christianity (for example the doctrine of Salvation). The one under scrutiny in this thread probably hasn't changed much other than to fill in what it means and/or to articulate it in more sophisticated language.

These all sound like advancements from man, not of religion or new input from god. So as man advances, the belief(s) is skewed more and more, therefore the "many more sects and denominations" schisms.

From my outside position the "many beliefs" seems to create more problems for man than it solves. Have not wars, exterminations and genocide occurred because of schism (diversity and diversion) in the one god belief? If not out and out killing then a creation of a system of classes where one is held up as the most correct and that class inflicts pain and degradation on the lower classes due to their diversity in belief?

Can you explain why an all powerful creator would remain silent and allow this to occur? Why has there been nothing in the 2000 years addressing this? (your parameter, I don't think there was ever anything, apparently the thought is that there was something before) Is this some strange god test to see who gets it right? Or maybe the one that out last the rest is the correct one? (don't forget there is still killing in gods name all across the earth to this day) Or could it be that this is just a man made fantasy? A fantasy used for manipulation?

They are advancements of man's understanding and thought. It is reasonable to see why doctrines would be more fully developed as centuries of thinkers debated the nuances of what the scriptures reveal about God, Jesus, Christian living, etc. 

It is important to remember that people kill/mistreat people. I was referring to the differences within Christianity. You might have included the differences between religions. Each religion should be judged on its own teachings/foundations. 

You ask why God would remain silent. Christians believe that God revealed everything we need to know as described in the NT. Jesus' teachings of "love your neighbor as yourself" "turn the other cheek" "love those that hate you", etc. (and I do mean a lot of etc.) illustrate that any violence or wars in the name of Christianity were flat out wrong. With regards to Christianity, always look for other reasons (rather than revealed theological thought) why people do bad things--they are always there.
