Karl Marx raged against the rich.
It is common for Marxists to rage against the rich. It is common for the rich to denigrate the poor and commoners as Gasset y Ortega did in The Revolt of the Masses. Either attitude is wrong. Rich and poor are on the same plane before God. He made both categories. Wealthy and impoverished alike are sinners before him. As Scriptures says, “He imprisoned all men under disobedience so that he might have mercy on them all.” (Romans 11:32)
Jesus dealt as easily with the wealthy as with the impoverished. He was equally master whether he mingled in the top or the bottom of society. He rebuked the rich as readily as the poor. There was no favoritism with him. In this, as in all things, he lived out the Word of God.
