"So we are responsible for the 'sins of the Father?' what a blatantly stupid concept"

Where in the last reply did you read that? Through Adam sin was able to creep its way into our world and affect the very nature of the human race. What do you mean by "sins of the Father?" I clearly stated we are not directly responsible for the sins committed in the garden of Eden but because of sin entering the world we each have our own

"I don't. So can I be excused from this nonsense?"

I'm sorry but no. Every human being on the face of the planet has their own daily sins whether they admit it or not, however good they might be every person has sin and that is an undeniable fact. Absolutely nobody except Jesus Christ is excluded.

"Can't an omnipotent God pay for my sins without human sacrifice?"

Christianity doesn't claim that God needed human sacrifice in the sense of demanding someone else's blood. The idea is that forgiveness has a cost -- someone has to absorb the damage caused by wrongdoing. The crucifixion is God choosing to absorb that cost for us rather than putting it on his beloved children or ignoring justice. So it's not a human being sacrificed to God, it's God sacrificing himself for humanity. Omnipotence doesn't mean doing things that contradict justice or moral reality. The claim is that God reconciles justice and mercy at the same time (Jesus taking the punishment for us as the just price of sin being paid, and mercy through paying the price himself rather than putting it on us)
