>>>>>>the industrialized, Christian, Muslim, civilized, third, and entertainment worlds take their members from all over the face of the earth.
So Joe tells us. LOL! Joe, did you really mean to say that? Other than possibly "the entertainment world", all of those "worlds" are confined to far less than global locations. "The industrialized world" does not extend into some of the very poor, technologically backward, agricultural lands on the continent of Africa. Lands like China, India, Pakistan, Iran, Saudi Arabia, Laos, Thailand, and many more are not considered to be part of "the Christian world." Lands like Mexico, Cuba, Ireland, Brazil, Italy and many more are certainly not considered to be part of "the Muslim world."
Since we today refer to all of these "worlds" as "worlds", even though they all occupy locations which are far less than global, Peter could have been referring to an "ancient world" which also occupied a location which was then far less than global.
