Martin Luther:
“The works of monks and priests, however hold and arduous they be, do not differ one whit in the sight of God from the works of the rustic laborer in the field or the woman going about her household tasks, but that all works are measured before God by faith alone…..Indeed, the menial housework of a manservant or maidservant is often more acceptable to God than all the fastings and other works of a monk or priest, because the monk or priest lacks faith.”
