Economy

Cyclopedia of Biblical, Theological and Ecclesiastical Literature

"a term which properly means the arrangement of a household (οἰκονομία ), but is also frequently employed by ecclesiastical writers for the practical measures adopted in order to give effect to a divine dispensation. The Jewish economy included all the details of spiritual and secular government, but the Christian economy, belonging to a 'kingdom not of this world,' has no direct reference to political arrangements." (See Dispensation).

The Nuttall Encyclopedia

"the right arrangement of things," and distinct from Frugality, which is "the careful and fitting use of things."
