In the United States tradition that arose in the early nineteenth century, religious bodies were spiritual families with "brothers" and "sisters" that assisted in each other's lives outside of services. Descriptions of just how involved in daily life churches were can be found in e.g. Boles's 'Religion in Antebellum Kentucky.' Much unofficial societal organization flowed from there. Granted this was not the case, or not as much the case, in churches that predate that period, say, urban Episcopalians.
