So close, yet so far!
You admit that the Lamb, the Beast and the Sword aren't literal, but you just can't seem to take it to the logical conclusion.
None of it is literal!
Most people interpret Revelation as being at least part way literal, and yet, no one seems to be able to understand it. Why is that?
1Co 2:13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
1Co 2:14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
I shall give you an example of comparing spiritual with spiritual.
Ecc 3:18 I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.
Dan 4:32 And they shall drive thee from men, and thy dwelling shall be with the beasts of the field: they shall make thee to eat grass as oxen, and seven times shall pass over thee, until thou know that the most High ruleth in the kingdom of men, and giveth it to whomsoever he will.
Dan 4:33 The same hour was the thing fulfilled upon Nebuchadnezzar: and he was driven from men, and did eat grass as oxen, and his body was wet with the dew of heaven, till his hairs were grown like eagles' feathers, and his nails like birds' claws.
It's all spiritual, not literal. ...And just for the record, swords in scripture represent scripture, not literal weapons, even though it is very much used as a weapon. There's a reason that it is two edged. One edge is the literal interpretation, which most people have, and the other is the spiritual interpretation, which most people do not have.
Rom 8:6 For to be carnally minded is death; but to be spiritually minded is life and peace.
Carnal just means physical or fleshy. The carnal mind like literal things.
