Jesus was not “Born Poor”. To coin a biblical phrase, He owned the cows on a thousand hills. The Earth was his creation. Everything on the planet was and is His.
As to his parents being “poor”, it should be noted that Jesus was born in a manger because “There was no room in the Inn.” They had the resources to stay at the Inn, but there was simply no room.
What if Jesus was born in Brooklyn somewhere on Avenue P and had the oldtime NY accent?
Would the last supper have been of bagels, lox with schmear and a bottle of Manischevitz wine? Oy vey..
