The Book of Common Prayer (simply "the prayerbook" to adherents) is very useful. An online version can be found at https://www.churchofengland.org/prayer-worship/worship/book-of-common-prayer.aspx
It includes the "Articles of Religion" (also called "the Thirty-Nine Articles," "the XLIX Articles," "the Articles of Faith") here:
The Church of England follows the "Athanasian Creed."
The Book of Common Prayer also includes the Catechism, which is not formally the source of church doctrine but is, dare I say it, the official FAQ? The Catechism contains the fundamental principles of doctrine which are supposed to be learned before confirmation, which often happens in late adolescence.
P.S. The branch of the Church of England in the United States is called "The Episcopal Church," and adherents are called "Episcopalians." "Bishop" is the Anglicized form of the Latin "Episcopus" and literally means "Overseer."
