Der römische Stuhl und die armenische Christenheit zur Zeit Papst Innozenz IV. Die Mission des Franziskaners Dominikus von Aragon nach Sis und Hromkla und das Lehrbekenntnis des Katholikos Konstantin I. Bardzrbertsi

The article deals with the relations of the Latin Church and the Armenian Church of Cilicia in the first half of the XIIIth c., especially with the problems of union between pope Innocent IV and the Armenian catholicos Constantine I. Bardzrbertsi. The historical analysis is based on three documents: 1. the pontifical bull Cum simus super, which was addressed in 1245 to the oriental patriarchs; 2. the letter of Constantine to the Armenian king Hethum, written in 1246 by Vardan Areweltsi, concerning fifteen matters of dispute between the Roman and the Armenian church; 3. Constantine's confession of faith which was sent to Rome in the same year. The letter of Constantine- Vardan is transmitted in the “Book of Letters”. Its content has not been known till now. It is cited for the first time in great detail. The Credo of Constantine is fully translated into German. These documents shed also light on the papal mission of Dominique of Aragon to Sis and Hromkla in 1246 and his discussions with the Armenian catholicos on different religious and ecclesiastical points of view
