Yea true, but there's only one Christ or messiah that the Jewish bible teaches. Don't get too caught up on the terms/title.
But yea there's been many ANTI Christ figures and there will be one this generation. History repeats itself that's why it's all predictable. But the time in revelation is speaking of a specific time in the future although it can be applied to many times throughout history. Same thing different era but this current era is unique. We have technology that makes bible prophecy possible....
But yea there won't be another Messiah or Jesus Christ. No other religious figure is coming like him... None had since. It wasn't Muhammad or whoever else people say will come. That happening contradicts the whole term, its role and its meaning and even the bible. How can you believe or entertain any thing the bible says about the future while believing something will happen in that period that contradicts what's written in the past? Might as well make it up as you go....
So no I don't agree there will be another "Christ" Unless you're talking about Christ returning or a "Christ like figure" emerging in the future but that could also be seen as a false Christ or the anti christ.
I wouldn't trust anyone walking around saying they're Christ no matter how much good they're doing
