This is the first that I have heard of them. The apparent inspiration for the phrase had never meant to be interpreted to justify a lack of charity. Only those with poor understandings of Christianity’s history and teachings would think otherwise. I would think the “uncharitable interpretations” of the phrase “God helps those who help themselves” are by those with poor understandings as well.
The status quo "in god we trust" is universally hopeful.
"God help us" can sound helpless (cheek in tongue)
