We also discuss the spiritual and liturgical patrimony of these particular Churches, the concepts of «rite», «Patriarchate» and «sui iuris Church», their own liturgical instructions of these particular Churches (specially the conciliar Indications in th a t referred to the communicatio in sacris with these Eastern Catholic and Orthodox Churches), as are stated In the Orientalium Ecclesiarum Decree (1964) and In other conciliar documents.
