“Some idea of the real estate and other forms of wealth controlled by the [Ed.: Roman] Catholic Church may be gathered by the remark of a member of the New York Catholic Conference, namely ‘that his church probably ranks second only to the United States government in total annual purchase.’ Another statement, made by a nationally syndicated Catholic priest, perhaps is even more telling. ‘The Catholic Church’, he said, ‘must be the biggest corporation in the United States. We have a branch office in every neighborhood. Our assets and real estate holdings must exceed those of Standard Oil, A.T.&T., and U.S. Steel combined. And our roster of dues-paying members must be second only to the tax rolls of the United States government’.” – Avro Manhattan (“The Vatican Billions”)
Well, then you should have no trouble coming up with actual numbers and references to prove they’re accurate.
