It wasn’t long before John [Chrysostom was condemning the extravagances he witnessed among the upper class of [Constantinople]. He preached that the earth was common property and that inequalities in wealth were tantamount to theft from God, who intended all to have access to the resources of creation.
The range of those in the city whom John offended was quite wide.
