The American bishops thus descend in the Apostolic succession from the bishops of Scotland, and to this day the nine crosses which symbolise ECUSA's nine original dioceses in its arms form a St Andrew's cross, commemorating the Scottish link. In Scotland, the Episcopal Church is so known because unlike the national state Church of Scotland (which is Presbyterian, i.e. governed by Elders), it is governed by bishops (in Latin episcopi). The word "Anglican" comes from the Latin word Anglicana which literally means English.
The Church
Other than the name difference the national churches are roughly the same, however the different groups (i.e., High Church, Broad Church, & Low Church) within the national branches of the Church may be proportionally different in numbers. Like many other Anglican churches, it has entered into a full communion relationship with the Evangelical Lutheran Church in America.
In the United States the Church has a membership of approximately 3 million, and has had such notable members as more than a quarter of all presidents of the United States and Supreme Court chief justices as well as roughly half of the members of Congress and Supreme Court associate justices.

The BCP is public domain; however, any new revisions of the BCP are copyrighted until they are approved by the General Convention. After this happens, the BCP is placed into the public domain. The text is controlled by the Custodian of the Standard Book of Common Prayer .
