IF, and only if, you are talking about the pastor-run churches that DEMAND tithes, then I am in agreement with you.
I think that MOST believers would be.
The problem is, you are NOT dealing out "common sense and Biblical truth".... you are dealing out your own pre-conceived notion that ALL churches that have paid preachers, buildings, etc are in that same category.. This is simply NOT TRUE.
I have found that the majority of churches have some type of program dedicated to do "benevolence" work. Guess where those funds come from? The free will giving of the body...
Our church routinely has a fund of somewhere around $80,000 dollars per year, and it is usually depleted sometime around 10 months into the year. We also do financial counseling for those that have gotten into a financial bind through bad decisions and money management. (give them a fish, or TEACH them to fish) When the fund runs dry, money from other budgeted funds are transferred over to cover the shortfall. This is in a church with about 900 members. Yes, we're really soaking the poor, aren't we.
Your obvious belief that only YOU hold the truth about how the ecclesia should be "done" makes it very difficult to have a discussion with you. You should open your mind to the fact that only a relative FEW churches are as you picture them. The problem is that those few are usually on television, spreading their doctrine of "doctrinal theft". It seems that these are the only examples you have of what churches really are.
I strongly suggest you get off your couch, and go out into the world and experience the "good" churches. You will be pleasantly surprised.
Blessings....
