1- I didn't engage in name-calling, I called out heresy.
2- Great tribulation exists, but when the word "the" is placed before it,
it becomes unscriptural fiction, just like "the antichrist" and "the rapture".
The literal says, "The ones coming out of the tribulation great." Jesus also called it a time of great tribulation that will be unequaled, inferring that it will be a time of unprecedented tribulation set a part from all others. Therefore "The" as the definite article is setting it a part from any other tribulation.
Don't know why you would say that the antichrist and the gathering of the church are unscriptural, when you can read all about it. I suppose if you close your eyes to it or adopt the teaching of men you can circumvent or distort it.
Regarding the antichrist, though John states that there many with the same spirit, there is one individual who is coming, also referred to as "The Man of Lawlessness" who will come and who will be that ruler over the earth. The beast that comes up out of the Abyss will be his spiritual counterpart.
"Little children, it is
the last hour, and as you have heard
that antichrist is coming, even now
many antichrists have appeared, whereby we know that it is
the last hour."
So, "that antichrist" is referring to a single individual and that there were and are many types of antichrists. However, thee antichrist is still coming. He is also referred to as "The Man of Lawlessness" and will be spiritually empowered by the beast who comes up out of the Abyss. By the way, the "antichrist" is in the singular.
