Is today's Christianity much different to the Christianity that was allegedly being practiced 2000 years ago?

The first point is the bible; the Christians 2000 years didn't have a bible. The second point is all that dogma and all those weird rituals the Catholics made up during their thousand year reign of darkness that ended with the reformation. Eating a Jesus cracker would have made the original Christians cringe, right? And this nonsense about a trinity would have made them go, "Huh?" wouldn't it? And imagine their reaction if they saw Pentecostals rolling around on the ground babbling like baboons and claiming, "I can feel the holy spirit! Yee haw!" They would think it was some weird new religion, not Christianity, right?
