Charity was once the provenance of the Churches, but now that the State has its fingers in the pie, it wants to kick the Churches out.
State forbid that a mention of God might come along with some actual Christian Charity.
If I decide to give of all the Lord has blessed me and mine with, that's charity.
If the State takes the money from me via taxation (at gunpoint, ultimately), it's reallocation of wealth by force, not 'charity'. More like robbery.
