The Number of the Beast
There is another possibility: 666 is a magic square. From very ancient times, philosophers and mathematicians were fascinated that the numbers 1–36 could be arranged in squares so that each row and diagonal would add up to the same sum (the same principle as modern Sudoku). One magic square has four rows and two diagonals that each add up to 111. The six lines of 111 equal 666. Each magic square in ancient Jewish and Greek tradition was also associated with a celestial body. In the case p 209 of the 666 square, that body was the sun, which was associated with Zeus, the highest god in the Greek pantheon.
Zeus was often associated with Baal and the mythological north (tsaphon) of Canaanite religion. Most relevant to the Beast of Revelation is Baal’s (and Zeus’) title, “lord of heaven” (Baal-shamem). It is possible that the “abomination of desolation” in Daniel 9:27 (shiqquts-shamem) is a play on Baal-shamem, since the Old Testament writers sometimes substituted words that meant “shame” or “abomination” into proper names that formerly contained “Baal” (e.g., Mephibosheth, Ish-Bosheth). This would mean 666 is a symbol for the abominable Baal, the dark lord of the Old Testament world—satanic power in New Testament thinking.
6 is an imperfect number, 7 being a perfect number. Thus 666 represents the “superlative imperfection.” The Sib. Or. 1.325–28 notes that the sum of Jesus’ name Iēsous is 888. Perfection would be represented by 777 and “superlative perfection” by 888. Therefore 666 represents the ultimate evil posed by the antichrist in opposition to the ultimate good offered by Jesus Christ.
