List of Christian denominations (or Denominations self-identified as Christian) ordered by historical and doctrinal relationships. (See also: Christianity; Christian denominations).
Some groups are large (e.g. Catholics, Lutherans, Anglicans or Baptists), while others are just a few small churches, and in most cases the relative size is not evident in this list. Also, modern movements such as Fundamentalist Christianity, Pietism, Evangelicalism, Pentecostalism and the Holiness movement sometimes cross denominational lines, or in some cases create new denominations out of two or more continuing groups (as is the case for many United and uniting churches, for example). Such subtleties and complexities are not clearly depicted here. Additionally, some groups viewed by non-adherents as denominational actively resist being called a "denomination" and do not have any formal denominational structure, authority, or record-keeping beyond the local congregation; several groups within Restorationism fall into this category.
