Have Christians been steadily adding to their list of things without tangible evidence that they must believe?

...in order to get to super, happy fun-land when they die? The list is things like; there’s a god and it is the Judeo-Christian god, the bible is the word of this god, there’s a heaven and hell, the Jesus myth is based on events that actually took place, prayer affects reality in some way, etc, etc. What I’m asking is; are there a few things on the list now that weren’t on there when people first decided to stop practicing their existing religion and become Christian?
