Knight of Honor (Ehrenritter). There are also classes of Honorary Commander (Ehrenkommendator), given to Knights of Justice who have rendered distinguished service to the Order, and Honorary Member (Ehrenmitglieder), which can be bestowed on men (including non-evangelical Christians) who do not belong to the Order but have given it some extraordinary service. Charitable works Through its Johanniter-Unfall-Hilfe ("Saint John Accident Assistance"), its hospitals, nursing homes, hospices, and other institutions, the Order today is a major provider of medical and rescue services in Germany and, to a lesser extent, of comparable services elsewhere in Europe, Africa, and the Americas. These services are similar to the St. John Ambulance in many Commonwealth nations, and to various organisations affiliated with the Sovereign Military Order of Malta. All are carried out under the auspices of the Christian faith. Additionally, spiritual retreats and other activities of the Order concentrate on the spiritual formation and development of Christian citizens in the modern world. Insignia The cloak of the Order is plain black with a large, white, linen eight-pointed cross on the left breast. For most knights, the cloak is black woollen (to which French knights add distinctive white woollen collars) with a plain lining, but the Herrenmeister’s cloak is of black velvet lined in satin. The cloaks of most knights are closed only at the neck, but the Herrenmeister, Commanders, Honorary Commanders, and Knights of Justice also wear a long black cord called a cingulum. The insignia, also known as crosses of honor, are no longer bestowed by the Order automatically (reception into the Order now involves only ceremonial robing with the cloak in a church service). Knights of Honor now must have rendered five years of service to the Order before a cross of honor is granted. Promotion to Knight of Justice requires at least seven years of distinguished service. The basic insignia of the Order is a white-enamelled Maltese cross. The crowned Brandenburg (later, Prussian) eagles between the arms of the crosses date from 1668; they are gold for Knights of Justice, Honorary Commanders, Commanders, and the Herrenmeister, but, on the crosses of Knights of Honour and Honorary Members, the eagles are enamelled black with only the tiny crowns on each eagle's head left unenamelled gold. The closed crown of the king of Prussia on the Herrenmeisters cross and the crosses of Commanders, Honorary Commanders, Knights of Justice, and Honorary Members dates from the
