Luther remarks (in his Sermons on John)
It is a fact that the nobility today regards all other classes as a stench in their nostrils. God did not grant you your nobility as a cause for conceit, but for useful service… [But] a nobleman acts as the peasant’s tormentor and vampire; a rich citizen bleeds a poor one; so the peasant, too, will skin and flay the townspeople. This is the general custom in all walks of life. It has all degenerated into boasting and blustering. But God did not ordain it that way. This is not the purpose God had in mind with a king, a nobleman, a rich burgher. No, His plan was that these all were to be agents in the service of man’s welfare.*
Did you hear that? God gives wealth and power not so that the recipients could lavish them upon themselves but that they might serve the well being of others.
