Churches do charity work because they can write it off on their taxes.
No, wait, they can't. Also churches have a bad habit of being picky of those they help. Often times, conversion is necessary first.
Preamble to the Constitution of the United States of America: We The People "We the people of the United States, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, PROMOTE THE GENERAL WELFARE, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this Constitution for the United States of America."
"The Congress shall have power to lay and collect taxes, duties, imposts and excises, to pay the debts and PROVIDE FOR THE common defense and GENERAL WELFARE of the United States; but all duties, imposts and excises shall be uniform throughout the United States;..."
Twice in our Constitution it mentions "general welfare" What constitutes 'General Welfare'? Does this not cover anything the government does to help its citizens live a better life? To ensure that all citizens have access to the basic necessities of life. Food, shelter and health care.
I really do wish Congress would pass a law reinstating the Constitution as the law of the land.
