To my knowledge, there have been at least 4 antichrists, so if we had one now, I'd up my rosaries like crazy and let it pass.
We don't really need to get our panties in a bunch until they rebuild the temple in Jerusalem, the seat of the final antichrist, which is the goal of Jєωs in order to disprove the divinity of Christ and the truth of Judaism. I think that's still a long, long way off.
Besides, when padre pio was asked how long his work would go on, he answered 15,000 years, so I figure we have a while to go yet.
