So...how did you come to the conclusion that what has been excepted for the better part of two millenia is wrong?
Did I miss some awesome book, or what?
If you mean "accepted," then your premise is incorrect.
Christianity was largely a Meditteranean religion for the first 1000 years of its existence. In other words, it was unheard of or rejected by 90% of the world's population until around 1100 AD when the Catholic church began violently imposing its religion around the ancient world.
Through their campaign of terrorism and lies, they spread christianity for the next 1000 years and they've been able to deceive about 33% of the world.
I never came to a conclusion that christianity is wrong, I just never believed and never will. I prefer not to follow a Jewish cult religion that has a history of murder and deception.
