RT Article T1 Einig in der Theologie der Ämter?: das Amtsverständnis in Lumen Gentium aus der Sicht der orthodoxen Theologie JF Zeitschrift für katholische Theologie VO 137 IS 3/4 SP 314 OP 333 A1 Vletsis, Athanasios 1956- LA German PB Echter YR 2015 UL https://www.ixtheo.de/Record/173769283X AB In »Unitatis redintegratio« the Roman-Catholic church accepts the office and the sacraments of the Oriental churches. On this basis, the article explores whether the Orthodox church can say the same about the theology of office and the sacraments of the Roman-Catholic church presented in »Lumen gentium«. It, then, discusses what both churches have in common and where the differences are. The final section marks the open tasks that still hinder a consensus between the two churches.
