No, no one has taken that mark because it doesn't yet exist.
Think it's symbolic? Then, please answer Reynolds' question in post #61.
Reynolds' question: "
How does symbolism prevent those without it from Buying or selling?"
Let's look at the immediately context of that reference:
Revelation 13:16-18
16 And he causes all, the small and the great, the rich and the poor, and the free and the slaves, to be given a mark on their right hands or on their foreheads, 17 and he decrees that no one will be able to buy or to sell, except the one who has the mark, either the name of the beast or the number of his name. 18 Here is wisdom. Let him who has understanding calculate the number of the beast, for the number is that of a man; and his number is six hundred and sixty-six.
In the Roman Empire at the time of the writing and first reading of the Revelation, Caesar had his mark (his seal) on commerce. His mark had to be affixed to commercial documents giving permission to trade and his image was on the coins, making it extremely difficult to "buy or to sell" without encountering the mark.
But the "mark of the beast" is not the focus of this passage, it points to the person at the top of the government, whose "number" is 666 (or 616 in variant readings) - the name can be calculated as "Nero Caesar" from BOTH 666 and 616.
Once you step away from the microchip speculation, it is quite easy to sort out when you understand the symbolism and Greco-Roman culture.
