It would be a very complicated and weird situation if Jesus 'came back down to Earth'. The Muslims would react and say 'Oh look, it's Nabih Isa coming back down to Earth to do what he didn't do 2 centuries ago!', and the Christians would react like 'Oh my god, it's god!', and the Jew's would be like 'it's my messiah!'. Very very complicated. Vice versa, he's still the same person to all those 3 religions. Not being a 'religion-ist' or whatever you'd like to call it, but if he's the same person that applies to all those religions, then why do those 3 religions in particular, always cause conflicts between one another? It baffles me, really.
