Being familiar with faith and criminal related revolutionary elements embedded within some aspects of current Catholic culture, such as liberation theology, is important, and McNeil (1963) makes a relevant historical point here:

“Given a cause to make robbery respectable and leaders who knew how to combine preaching with pillage, brigandage could speedily snowball into a formidable military rebellion. The first Wahhabi “empire” of Arabia arose in this fashion in the mid-eighteenth century, growing rapidly until a well-equipped expeditionary force from Egypt suppressed it in 1818. Analogous occupational groups in the Balkans—shepherds, muleteers, mountaineers—also played a significant part in the history of the Serbian (1803—13) and Greek (1821—30) revolts; for the military leadership and the best fighters of both movements came from brigand bands organized to serve the new ideal of nationalism.” (pp. 695-696)
