Fogleman (2003) examines the theological, demographic, and sociological roots of factional clashes between Moravians and their more traditional German Lutheran and Reformed coreligionists, focusing on mid-18th-century communities in Pennsylvania and New Jersey, where these confrontations were frequent and sometimes violent. Moravians' beliefs centered on a feminized Holy Spirit, the right of women to preach, sacralizing the sex act, and metaphorically re-gendering Jesus Christ. These teachings were perceived as threats to more mainstream Christian articles of faith, which stressed the masculinity of the Trinity as the theological cornerstone of the nuclear patriarchal family, the core structure in upholding moral and social order. As Moravian preachers far outnumbered the very few Lutheran or Reformed clergy in the mid-Atlantic colonies during the 1730s–40's and because the Moravians welcomed anyone into their church services, most German Pietists viewed Moravians as more than harmless heretics. Moreover, in the temporal context of a period of intense European immigration to the colonies, the Moravians were seen as challenging the long-term social stability of the colonial community as a whole. Although the Moravians never became a dominant sect in the region, the perception of them as a serious religious and social threat highlights the significant role gendered power issues have played in religious controversy in North America.
