Who wrote that headline? Sure, it’s the 350th anniversary of the 1662 Book of Common Prayer, but there were several others before it: 1549, 1552, 1559; and The Episcopal Church’s BCP is more dependent on that of the Scottish Episcopal Church than the 1662; which is why those documents that claim the 1662 Book of Common Prayer is shared by all Anglicans is just wrong.
The “genius” of the Book of Common Prayer is not in the 1662 edition, but in the work of Thomas Cranmer who was largely responsible for the 1549 and 1552 versions and in the 1559 book that tried to balance the more Protestant and Catholic tendencies of the two earlier ones.
