During whose reign was the Book of Common Prayer written for use in the Church of England?
Edward VI.
Edward VI's short reign left one lasting mark: the Book of Common Prayer, written for services in the Church of England. Remarkably, a version of it is still used in some churches today. Keep it apart from the King James Bible, which came later under James I and is a Bible translation, not a prayer book.
Test Trap. the Book of Common Prayer belongs to Edward VI's reign; the King James (Authorised) Bible belongs to James I's reign. Charles I's revised Prayer Book is a third, separate item.
Why it matters: A known trap: the Book of Common Prayer (Edward VI) is often confused with the King James Bible (James I).
Memory hook: Edward's prayers, James's Bible: Prayer Book first, Bible later.
