the formula for making the church change its theology: stop payment

there were two reasons that temples were sacked during warfare in the ancient world.  One of them is theological domination: my god is stronger than your god and to prove it, I'm going to demolish your god's temple.

The other was simple and practical:  temples were the ancient world's safety deposit box.  You didn't put your money in the bank or hide it under the bed.  Once you had paid your dues to the cult in which you participated, you gave the priest your money to make sure it was kept safely.  The unfortunate consequence of that practice was that if and when your community was attacked, the attackers made sure to demolish and loot the temples.

In many ways, the world has not changed much.  The Church (both Catholic and Protestant) still wants money.  Part of the reason that popular theology changed from threatening with eternal damnation to encouraging "spiritual growth" has to do with guilt over the catastrophic result of the Church's demonization of Jews as part of its claim to ownership of text via adoption.  Part of the reason for the change has to do with retaining the paying customer, the pew-filler.    The promise of "spiritual growth" is a good draw to retain existing congregants, and to attract new ones.  Encouraging, "positive" theology makes for a happy congregation.  A good congregant gives money to its church of choice.

One of the [many] manipulations used by the Church on congregants is "you cannot serve both God and Mammon."  This is used to create guilt in congregants so they feel compelled to "share" their earnings with the Church.  It is applied to both Catholics and Protestants (and one of the few times that guilt works on Protestants--despite the fact that Protestant theology holds that earning well is proof that the earner has found favor with God).  It is a very useful manipulation.

A church that cannot retain its paying congregation goes out of business.  In the Catholic world, this is reflected in the closing of parochial schools, and of folding parishes into neighboring parishes.

In the Protestant world, the church closes its doors.  Its pastor is out of a job. and has to find another congregation willing to hire him/her. 

It will not be possible to change the Church by  trying to persuade Church hierarchy of the need to change to meet the current social climate.  The Church does not care about the current social climate.

The Church does care about losing money.  Thus, the obvious way to compel the Church (both Catholic and Protestant) to change is to withhold money.
