This denominational family tree offers some interesting commentary on ecclesiology. The Lutheran Church stands prominent in the central stream of the Christian faith, while other traditions branch off here and there. The "Mediaeval Church" ends precisely at 1517 AD, no surprise there-- the "Roman" Catholic Church branches off at this point, rather than holding a more ancient beginning.
Perhaps even more interesting, if somewhat odd, is the close of the "Ancient" Church and the beginning of the Mediaeval at 692 AD. This is a not-so-subtle exclusion of Nicea II, which condemned iconoclasm and was thus ignored as legitimately ecumenical by many Protestants. The Quintisext Council was held in 692, amending Constantinople III and IV (the quinti and sext) with disciplinary canons. Why a Lutheran catechism seemingly accepted the ecumenical status of a council usually dismissed in the West, I'm not sure- perhaps a slap in the face of Roman Catholicism? In any case, an interesting piece of the family tree.
Quakers and Anabaptists are distinguished from "Protestantism", which includes the Lutheran and Reformed churches (with all manner of Anglicans, Methodists, and "All Other Sects" swept into the Reformed branch). The Jesuits maintain the honor being a hump on the back of the Romans, while the "Greek Catholic Church" presumably stands in for all Eastern churches as a split during the Mediaeval period and away from the central branch of Christendom.
