I hope you're not trying to say the pope, because he is not the coming Antichrist for the end. That your mind automatically assumed Selah was pointing to the RCC suggests that's the working you have in mind.
But God's Word reveals the coming pseudo-Christ, "dragon", "another beast", "man of sin", "son of perdition", "that old serpent", will be Satan himself. The allegory God gives about Satan in Ezekiel 28 reveals that He is going to destroy Satan 'on this earth', and in sight of those who see it. And Lord Jesus pointed to after His crucifixion, about Satan coming (John 14:30).
No! My mind doesn't look for the pope/RCC to be anything of that spirit of antichrist.
If anything, the RCC is highly religious in their beliefs in Christianity.
It is simply that I have heard similar presentations, like that of Selah, which is almost identical to those who have made that claim against the pope. I foolishly assumed that Selah was doing the same.
Down through years since Martin Luther (Lutherans), a number of people and denominations have voiced their opinion that some of the popes were antichrist, simply because some were overbearing to the extreme of being "Pharisaical".
As for their being a singular man, that "church-inanity" loves to call "
THE Antichrist", being a "one man band, miracle man", I do not see it in the singular, but rather in the
plural, as there being "many antichrists".
In The KJV, one will never find the words: "the antichrist" put together, inferring a singular man, being a head of the grouping of antichrists.
By your words: "
But God's Word reveals the coming pseudo-Christ, "dragon", "another beast", "man of sin", "son of perdition", "that old serpent", will be Satan himself."
I don't see a singular
THE Antichrist, and here is why:
1. The words: "man of sin", "the son of perdition" and "the natural man", simply speak of every man, that does not have Christ as their Savior.
Jesus called Judas Iscariot to be "the son of perdition" (destruction). Apparently, there is more than one, as in many, just as there are "many antichrists". 1 John 2:18.
2. Also, the words: "beast", "the image of the beast" and "another beast", simply describe the empires and kingdoms of men.
God clearly defines how he calls them as such, in the book of Daniel.
3. As for "the dragon", "that old serpent", those words literally do reveal satan to be a fallen angel, who was cast out of Heaven down to this earth, along with one third of the angelic realm.
