Churches are institutions that should primarily exist in order to bring comfort, wisdom, fellowship, teaching, sanctuary, love, and other positive Christian attributes to those that attend that church and should also be good community members. Apparently, it's believed that in order for churches to perform well their function, they typically in one form or another, require tithes or donations or bequests from those that attend their church, and therein lays a fundamental problem.
The business of churches should never be about money, in any of its many forms and functions, for the true business of any legitimate church is to be a benefit for the constituents that attend such, and a benefit to their society, of which, if those constituents do not have the ready means to money, than the church can still exist by the simple gathering and congregation of like-minded people, joining together to worship their Creator, and to help support one another, which does not necessitate a building structure of any sort, though such a building brings creature comfort and convenience.
So too, our minds and hands are capable of producing and creating things that may not bring forth a direct monetary compensation, but are creative forms of labor that produce things of worth, that a church can then draw upon, so to pigeon-hole anybody and insist that a proper churchgoer must produce 10% of their paycheck and thereby donate it to the church coffers is fundamentally flawed, for it is in the volunteering of the congregant, the love and faithfulness of such, the service of church members to their God, as well as to their community, that defines the true effectiveness of what it truly means to be a Christian, and monetary donations while having their place are not the sine qua non of what merits true Christian faithfulness.
Churches that insist upon tithing as a point of honor or even to the insistence that paycheck stubs be provided to the church so that proper tithing can be calculated must be held accountable to the very things that they hold their constituents accountable for; that is to say, if a given church insists on its members religiously making their tithes, than that church, in return, should be completely transparent about its accounting books, in regards to where these tithes go, who in the church benefits, what bills are paid, what things are accomplished with the money, and further to the point, the very people providing the money for the church, should be permitted to have a strong say as to what is done with that money and the prudence or lacking result thereof of it.
Anyone, who gives up money to any church organization, or gives up labor, or gives up their free time to such an organization, has not only a right to know thoroughly what is going on at that church organization, but one can easily say, has a duty to know what is going on, for that money, and even that labor, or even their good head on their shoulders, are all gifts from God, and as faithful stewards of those gifts, it is their incumbent responsibility to see that these gifts are being appropriately and prudently utilized at that church for the betterment of the congregants and of society.
So that, churches that impress and insist upon their congregants that they require their financial donations, must be completely transparent with their devotees, for those that ask loudest and that make the biggest noise, will one day stand before the Most High God and be call to their account, whereas those that walk softly and lead by good example, recognize that "…the Kingdom of God is within you" (Luke 17: 21).
