I'll give you my views about the mark of the beast.
First, the quote :
13:18 Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number [is] Six
hundred threescore [and] six.
I think this man is Adolf Hitler himself.
What was the third reich ? A pagan mystical dictatorial regime.
In my view, by reading scriptures, 666 seems to be a sort of
state religion, a pagan religion, like naziism was, with a system of signs
(svastika, but also some other signs), numbers... With a mythology, but denying religion, and of course the people of GOD, judes.
I had the chance to have an access to some WWII german documents. It's a friend of me who collect book and ancients document who show me these. I
read some germans "comics", and also some mystical books. I know a bit german, but my friend helped me a lot in translation. There are more things
hides about this period than you will ever imagine.
The naziism doctrine was a mix of buddism (arianism, the manu law), Northern europe civilizations and celts...
There was the svastika, the arain sign, true...
But there was also the
triskele, a celtic sign :
666 >> You see, the triskele is composed of three 6 turning on the same axis...
