[livius]

The Church’s assets are hardly “liquid.” The great majority of Church property consists, literally, of property: that is, land and buildings, often of little value and certainly almost all difficult to sell or make liquid. In fact, maintaining these properties for use for church services, charitable work, etc. represents a huge outflow of money and that money actually is already going to the poor and the non-poor who receive these services.

Liquidity is a matter of opinion....'access to or control over' is perhaps a more appropriate term. I did google and review various sources before commenting on the matter. The estimate of wealth ranges from a ridiculously low assessment of $1 billion to a high of $3,000 billion.
