45. This sacrament is called "extreme unction" by both the Latins and the Greeks. At the second general council of Lyons convened by the leaders of east and west in 1274, Latins and Greeks approved and signed a statement of faith (Harduin, Collect., vol. 7, p. 695). The Greeks also call this sacrament the oil consecrated and sanctified by the prayers of priests, and the perfecting or fulfillment of the sacrament of penance. It is named euchelaeon in the Euchologion of Goarius, p. 346, no. 42 and p. 349, no. 1. The same name is used by writers of the next generation as can be seen in Georgius Pachymeres, Hist. Palaeol., bk. 6, chap. 32, and Possinus uses the same name in Bk. 1 Glos., p. 386 in Gabriel Philadelphius De Sacramento Euchelaei and Acta Ecclesiae Orientalis, vol. 1, p. 338. Moreover, the Greeks sometimes call this sacrament Heptapapadum. At the synod in Constantinople which met under Patriarch Giovanni Veccos in 1277, the Patriarch accepted the confession of faith agreed upon at the Council of Lyons. He wrote to the Roman Pontiff John XX (XXI) that: "We also accept extreme unction as we accept the other sacraments. It is named heptapapadum from our way of conferring it," that is, the service of seven priests, since the Greeks administer the sacrament in this way.
