Reading about an appeal turned down by the US Supreme Court, I see that the majority opinion on phrases such as “in God we trust” and “one nation under God” is that they are not affirmations of faith, but “a historic, nonreligious recognition of the faith of the nation's founders in a higher power as the source of all rights”.
As a European, I have a hard time understanding this particular view, though that's very off-topic here. More on topic, this reading fueled my curiosity about the existence of other such expressions in English, be them either about God directly or religions in general. My question is: are there other typical sentences or mottos which, while having a religious meaning if read literally, but are commonly understood as nonreligious? Maybe among States’ mottos, or those of army units’. I can't see where to start looking.
One thing, though: I'm pretty much aware of the large number of phrases, idioms, or sayings which feature the word God and can be used almost without risk in daily language, such as “for God's sake”, “God bless”, “God forbid”, “God help”, “God willing”, etc. I'm not looking for any such idiom.
