Taken from last weeks Watchtower study, para 8:
"8 What should be the motive for doing the
preaching work? It should not be to collect money and construct
elaborate buildings..... Despite
this clear direction, most churches are sidetracked by collecting money
or by making efforts to survive financially. They have to support a
paid clergy, as well as a multitude of other employees. In many cases,
the leaders of Christendom have amassed great wealth.—Rev. 17:4, 5."
OK for WT to be doing this but not Christendom?.
