I don't have chapter and verse like the other person, but I do recall that the Bible said Jesus's return would be triumphant. The only "stealthy" part of it (which the other person's quotes don't dispute) is that no one will know when (like, in advance). But when he does return, it will be no small feat. At least according to the Bible. Which I don't follow, so I can't claim to be an expert.
I always thought anyone claiming to be Jesus would find himself crucified.
Also, the Christians in power don't want Jesus, the god of man, they want Jehovah, he's their man, the one who punishes the gays and brown people and... yeah, I don't believe that shit, either. But the real Jesus would be asking these men in power how they have so much and why the people they rule over have so little.
