RT Article T1 Welches Ziel?: Kirchengemeinschaft nach katholischem Verständnis JF Catholica VO 77 IS 1 SP 66 OP 83 A1 Thönissen, Wolfgang 1955- LA German PB Aschendorff YR 2023 UL https://www.ixtheo.de/Record/1852493909 AB Discussions on the ecumenical vision have been running for years.

The prerequisites and conditions of a Catholic concept of church unity are significant in this context. Here, only a re-reading of important documents of the Second Vatican Council can bring clarification.
