Is Anglicanism Protestant?

Over the years, I have often reflected on the variety of expressions within the Anglican tradition. As a conservative Anglican, I have encountered people with opposing views. Some Anglicans identify as Anglo-Catholics. For the most part, Anglo-Catholics do not value the English Reformation, and they do not accept the label "Protestant."  Some other Anglicans go to a differing extreme. They may like the label Protestant, but they seem to think that Anglicanism is basically Calvinistic. While Calvin's views on soteriology and on the sacraments have been influential among some Anglicans, such views have never been the exclusive or official Anglican position. 

The examination of English church history indicates that neither extreme Anglo-Catholicism nor extreme Anglo-Calvinism is completely accurate.  As a matter of historical fact, Anglicanism is Protestant in some ways. Besides the often-debated Thirty-Nine Articles of Religion (which are a moderate Protestant synthesis), the principles of the Protestant Reformation permeate the traditional Books of Common Prayer and the thinking of most Anglicans of the past. These principles include supreme Scriptural authority, unmerited divine grace, and justifying faith. 

In sum, a broadly traditional Protestant understanding of Anglicanism seems most consistent with Anglican history. The Prayer Books, the Thirty-nine Articles, and general Anglican tendencies over the centuries support observers from a variety of Christian traditions who recognize that Anglicanism is a moderate and unique cultural stream of Protestantism.
