Supreme Order of Christ
The Supreme Order of Christ () was the highest order of chivalry awarded by the pope. According to some scholars it owes its origin to the same Order of Christ of the Knights Templar, from which came the Order of Christ that was awarded by the kings of Portugal and the emperors of Brazil. The Portuguese order had originally both a secular and religious component; by the 18th century, the religious component had died out. Dispute. The papacy insisted that the right of the Portuguese monarchs to award the honour had been granted by a pope in  the Papal Bull "Ad ea ex quibus" issued in Avignon on 14/15 March 1319. While the bull in itself does not explicitly grant to the pope the right to issue the order, successive popes since John XXII have done so. For many years the Portuguese monarchy disputed the right of the papacy to award the order, and in one famous case arrested someone for wearing the papal order. The position of the Crown of Portugal was that the only legitimate fount of honour was the Crown. The position of the Catholic Church is that the pope is the head of  every religious order and may appoint, at his discretion without the permission of its superior general, any individual he deems worthy. Senior papal order. As part of the general re-organisation of papal honours in 1905 by Pope Pius X, the papal Order of Christ was made the most senior papal honour. It was traditionally awarded to Catholic heads of state. Restriction. The usage of the order was restricted by Pope Paul VI in his 15 April 1966 Papal Bull "Equestres Ordinis" to Catholic heads of state to whom it might be given only to commemorate very special occasions at  which the pope himself was present. It has rarely been awarded since; the last award was made by Pope John Paul II in 1987 to Frà Angelo de Mojana, 77th prince and grand master of the Sovereign Military Order of Malta. With the death of King Baudouin of Belgium in 1993 there are no living members of the Order of Christ. In ecclesiastical heraldry, individuals awarded this order may depict a collar completely encircling the shield on their coat of arms.
