Ponder long and well this quote:

Another age may learn to look upon our use of activities much as we look upon the use of the sword by an earlier age. Because in them money takes so prominent a place, ours may one day be known as the age of financial Christianity, just as we look upon that earlier age as the age of military Christianity. As we regard the sword, so a later age may regard money. It may learn the wisdom of the Apostle and decline to use such an ambiguous weapon. If the sword was an ambiguous weapon which might easily confuse the issue, money, and activities which depend upon money, are not less ambiguous and may as easily confuse the issue. The time is not yet full. We have yet to learn the consequences of our use of money. --Roland Allen, Mission Activities (1927)

Doesn't look like we've made much progress on this one yet.
