so is it majority of christian beleaving in it or not?
You'd have to survey each individual Christian to get a definitive answer. I'd say that yes, the majority of Christians do believe that Jesus will come back, but that answer is based on the limited sample of the Christians I know. There could be lots of Christians I don't know who don't believe Jesus will come back (which may or may not include "silly bishops",) and the ones I know may in fact be the miniorty. That said, just because a belief if held by the majority doesn't mean that what that majority believes is actually correct. This principle is shown in Mark 8, when the disciples (of whom there were 12,) all believed one thing, and Jesus (1) told them they were wrong.

In a nutshell, the theory is that Jesus will come back to earth. The views people have on exactly how, when, and what will happen when He does are heavily debated, largely because these views are based heavily on prophecies which are interpreted in a variety of ways. Read and try to interpret the books of Daniel and Revelation to get an idea of why is such a heavily debated topic.

for what will he come back?
His Bride. Well, that's one of the things I believe, but there are other reasons as well.
