19 They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifested that they were not of us.

They swear to have been one of us, a biblical Christian and that they then walked away. They say Christianity is not good enough, not nice, not loving, not inclusive, etc. --Do not believe anything that they say. They are liars. Scripture that is posted above, shows us that had they truly been one of us, they would have remained one of us. Scripture shows they left so that we could know they were never one of us to begin with.

Scripture also shows while there will be the antichrist that will come, there are many antichrists in the world today. Many antichrists walk this earth. And they actually go out from among us.
