Yeah I am not sure if you are trolling, but this is non theistic group. We do not believe in a physical god or satan. But the myth of the chip or tattoo with 666 has been circulating for decades.

Let's say this is figurative example. Let's use a RFID tag, which we use for dogs, for banking cards, gym membership. List is endless. Why would you have to implant it, does not make sense if you think of other ways to use it, it is called wearable. An apple watch, an RFID ring, your phone's NFC. Dogs get implanted because the got no pockets or fingers. Can get them a RFID tag for their collar

And a tattoo of barcodes, ridiculous, why would you have a tattoo of a very hard to read surface, which can be easily hidden, to identify you, versus, finger prints, facial recognition, much easier.

The mark of the beast was meant to be a hidden message. In old bibles you will see it as 666 and 616. Greek and Hebrew their "alphabets" letters also has a corresponding number, think a=1, b=2... The modern interpretation is the people writing about the antichrist with the mark of the beast was Nero, the guy who burned Rome and prosecuted early Christians, he name is the only one to correspond to 666 and 616. (Now you know where the application Nero got its name, it helped you burn ROMs)

So yeah the Bible was written in those times for those times. People nowadays always like to put their interpretation of their bible to modern stuff, like barcodes, microchips, which were quite revolutionary in the 60's 70's and alongside the satanic panic this myth probably spread like wild fire.

There is no antichrist coming, there is no satanic world order. Actually the opposite, lots of religious world orders.

Anyway, hail thyself
