666 is not about messages or anything except the number of a man, the number of his name.
Rev 13:17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
Rev 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.
This is a well known example of how a man or his name can add up to 666:
Vicarivs Filli Dei (Vicar of the Son of God - Vicar of Christ) is a title of the Popes, it is latin, which was spoken in ancient rome, adding up the numbers of the latin letters in latin-roman numerology adds up to 666
1=5 V=5 X=10 L=50 C-100 D=500 M=1000
Perhaps this man is the false prophet, the beast out of the sea?
