The end of Christianity will come if full disclosure takes place peacefully. If our true place in the universe was finally exposed, it would wither away.
I intuitively believe that the primary obstacle to disclosure of ET's is the hegemony of the US. Once that is out of the way ( and thankfully, it seems to be fading fast), nations such as China, India and (oddly) Russia will drop the opposition to such revelations. Most people are not aware of how Tom Paine discussed this topic two hundred years ago when he rejected the Bible.
