Alright, seeing as you're unfamiliar with the messianic prophicies and what would be required of one before being called a christ, I'll explain (also perhaps this will help with the utter lack of intellectual conversation on this thread).
Messiah (keep in mind messiah and christ mean the same thing and are interchangable) means annointed one, specifically, an anointment into the service of god using prepared holy oils. (see Exodus 29:7, I Kings 1:39, II Kings 9:3, etc). Jesus was never annointed, yet people call him a word that means annointed, mostly out of ingorance.
The future messiah described in the prophicies was to be of the line of david, on the fathers side. Jesus had no earthly father so that's out (and we do not have mary's lineage so even if that could be counted there's no reason to think she was of the royal line). (Genesis 49:10 and Isaiah 11:1).
The messiah is to bring all jews back to their land of Isreal. (Isaiah 43:5-6). Not only did jesus not do this, but in fact christian nations across the world have mistreated and abused the jewish people for centuries, culminating in the holocaust of WW2, so if anything jesus's legacy was to do the opposite.
The messiah is to usher in a golden age of peace that would spread across the world(Isaiah 2:4). Again, jesus did not do that. In fact his own words suggest the opposite, as he flat out said he did not come to bring peace but a sword (a metaphorical sword perhaps, but the message that he would not bring peace was clear). And again, his followers, christians, have the dubious honor of being the most blood soaked religion ever to curse this world. So again, jesus's legacy has been the opposite of what the messiah's was to be.
The messiah is to bring the world to the truth of god, so that all as one would see him as lord(Zechariah 14:9). Yet because of jesus a new version of the god of abraham was born, a trinity of gods combined into one. And there are numerious offshoot religions that have tacken this further, and changed the concept of god even more from it's original, such as mormonism or the bahai. This is hardly a unity as to the truth of this god now is it? At any rate the point is that yet again jesus fails the test of the messiah.
The messiah was also to build the 3rd temple, yet this was not done either. (Ezekiel 37:26-28).
Also, as the leader of isreal, the messiah was to guide the people through proper observance of Torah, yet jesus repeatedly changed or ignored torah. In Deut. 13:1-4 we see that this alone is enough to identify the man as a false prophet.
So you see jesus in no way qualified as a messiah, and in most ways was the opposite or anti-messiah. It is therefore entirely apt to describe this character as an anti-christ.
