The Church of England's doctrinal character today is largely the result of the Elizabethan Settlement, which sought to establish a comprehensive middle way between Roman Catholicism and Protestantism. The Church of England affirms the Protestant Reformation principle that scripture contains all things necessary to salvation and is the final arbiter in doctrinal matters. The Thirty-nine Articles are the church's only official confessional statement. Though not a complete system of doctrine, the articles highlight areas of agreement with Lutheran and Reformed positions, while differentiating Anglicanism from Roman Catholicism and Anabaptism.
