Ah yes. Better watch out. Anyone who uses a Biblical phrase like that might be dastardly "wolf in sheep's clothing" with ulterior motives and not simply "the salt of the earth."
Besides, are you sure you've never used such a phrase without thinking about it? "Let he who is without sin cast the first stone." I'm sure you'd much rather "do unto others as you would have them do unto you". So maybe just be a charitable "Good Samaritan" and "turn the other cheek", even if you don't really like it, then. After all, "an eye for an eye" policy is fairly unpleasant.
Oh, who am I kidding? I'm just "casting pearls before swine" with this audience. (And being as foolish as "the prodigal son", at that.) I can see that "the writing is on the wall," and I won't get anywhere with anyone on this topic. I'll probably even get downvoted for this, but oh well. "Sow the wind" and "reap the whirlwind" as they say. (Hacker News really can be "the blind leading the blind" sometimes.)
Both article 6 and the first amendment make it in very poor taste.
You may personally appreciate it, but suppose he had been quoting different religions texts. Say the need to nourish Mayan gods using sacrificial blood.
I worry that people are now so illiterate that they do not recognize that the "render unto Caesar…" quote is a historical basis for the division between church and state in the Christian world. Astonishingly, they view the Government citing the quote – the origin of separation – as a threat to separation!
I agree, but I think using this saying is within reasonable bounds compared to a coach leading school-affiliated prayer. The decision even left out the religious that followed.
