"Taught by many", what does that have to do with anything?
I prefer to let scripture tell me what is or isn't. In the epistles of John you will find full descriptions. To add to what John was very clear about I think is sloppy and dangerous.
Personally, I think the Church has been brainwashed by Hal Lindsey and his money machine. After he made millions, everyone else got into the act, and now it's dogma!
Ask someone in Russia to whom and when Revelation took place, or China, someone outside the influence of this modern day non-sense, they will tell you first century, in fact we know who the letters went to by name!
People misunderstand, the book of Revelation is like Isaiah, or the other prophets. They always start with the now, then in the near future, then in the distant future.
Look up Partial Peterism, not the whacko Preterism that says that Christ has already bodily returned.
Or Here where John say's
Revelation 19:
11And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
12His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
13And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
15And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
16And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.
17And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God;
18That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great.
19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.
20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
21 And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.
Satan is caast into the bottomless pit for 1000 years then loosed when he pulls an army together,
Revelation 20: 9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
notice the one on the horses name "his name is called The Word of God." Notice also "16 And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS."
Sounds real clear Christ comes to earth and defeats the Beast and the False Prophet casting them into the lake of fire. Then sets up His Kingdom and finally cast Satan into the lake of fire where the Beast and False Prophet are. Nothing like this has happened.
