The third is the Postmilleniallism view, that Christ returns after the millennium because the Church will expand and will have evangelized all of the world (Rev. 19:11-21).
People with this view usually subscribe to the Futurist view. Their main point is the victory of Christianity over the entire world. Thus, Christ will not return until all people groups have been reached. They make no distinction between the rapture and Second Coming, as most view it as one event.
