What I don't use, the government takes away for the benefit of itself and for the benefit of those it deems worthy of its largesse. If the Church feels the poor in the USA are not adequately provided for, it needs to petition the entity that took the tithe it otherwise would have had. My 10% Church tithe resides in the coffers of US governments, State and Federal.
I beseech the Church to plead its case for the poor to the legislators that know better than myself how to care for the needy.
And pays for unionists, abortions, morning-after pills, subsidies to anti-Christian initiatives, bailouts, foreign governments, advertising, pork and waste.
