Ah, I see yor point. However, I think this was only true after the Reformation, as Catholics prior to the Reformation were expected to work hard to maintain the Body of Christ, i.e. the serf was bound by God to work his Master's land and the Lord was bound by God to protect his vassals, while the Priest was bound to pray for the souls of both.
Thence we have the "Three Orders" of life, those who Work, Fight, and Pray, which went to make up pre-Renaissance Europe.
