And no I really doubt marilyn manson is the antichrist. the antichrist will be someone of immense power and will probably be good looking, intelligent, and charismatic people will follow him because of his deception and leadership skills and he will rise to power.
marilyn manson is a freak the real antichrist will be the least likely person claiming to work in the name of peace and general good but sowing the seeds of evil.
It is highly possible that there is always an antichrist on the earth due to the fact satan does not know when The Day of The Lord will come.
Let him who hath understanding reckon the number of the beast for it is a human number, its' number is Six hundred and sixty six."
Revelations Ch. XIII v.18
he is the son of lucifer and is born as the incarnate human form of evil!
he whom bears the mark of 666 on his head and is known in the new and old testemants (spelling?) as "the beast"
he is a false prophet and does the work of his father to erradicate the word of god!
