Then there are the Christians who practice numerology and have received secret messages from God about 666.
Well now to be fair, Revelation does exhort those “who have wisdom, let them calculate the number of the beast.” The operative phrase, I will emphasize,(and to meet you half way) is “have wisdom”. There have been a lot of folks that seem to have no expertise(and therefore have no business) trying to “calculate” and identify the coming malevolent one! You wouldn’t find me in that number, I have no wisdom when it comes to that sort of thing...I could barely pass 2nd level algebra and trig in high school!(The final exam of which I think my teacher awarded a few brownie points because i stayed until the bitter end of the allotted time an hour after the last person had given up and left. My teacher told me that the proctor had remarked that he admired how I just kept trying and trying until the 3 hours were up. My math teacher and I actually became friends after that!)
