The religiosity and practice of the working class is a subject about which their is much disagreement among historians. The sources, even recorded oral testimony, are difficult to interpret, and probably fail to show the degree and variety of religious life.
Some historians held that the working class was less religious because it was alienated by and resentful of class distinctions within the Church. McLeod states that this is a biased position that accepts middle class definitions of religion and evaluations of other classes religiosity. Church attendance, he argues does not equate to piety; nor does behavior, for that matter.
