*All Christians who have ever lived, live currently, or will live in the future, regardless of personal denominational affiliation, membership or attendance (sometimes referred to as the "universal Church" or the "invisible Church")
+
*A group of believers organized in an individual [[congregation]] (e.g. the believers comprising the membership and regular attenders of [[Prestonwood Baptist Church]]), regardless of any denominational affiliation or lack thereof
+
*A group of congregations organized in a [[denomination]] (e.g. the [[Roman Catholic Church]] or the [[Southern Baptist Convention]])
