Luther's jackal, the "gentle" Melanchthon, specially signalized himself by urging on the feudal barons with Scriptural arguments to the blood-sucking and oppression of their villeins.

A humane and honourable nobleman, Heinrich von Einsiedel, was touched in conscience at the _corvees_ and heavy dues to which he found himself entitled.

He sent to Luther for advice upon the subject.

Luther replied that the existing exactions which had been handed down to him from his parents need not trouble his conscience, adding that it would not be good for _corvees_ to be given up, since the "common man" ought to have burdens imposed upon him, as otherwise he would become overbearing.

He further remarked that a severe treatment in material things was pleasing to God, even though it might seem to be too harsh.
