Saint Francis of Assisi 
Of the Manner of serving and working [EPUB ebook] 

Let the brothers in whatever places they may be among others to serve or to work, not be chamberlains, nor cellarers, nor overseers in the houses of those whom they serve, and let them not accept any employment which might cause scandal, or be injurious to their soul, but let them be inferior and subject to all who are in the same house.
