Abstract
Among the issues remaining to be addressed along the path to reconciliation between the “Eastern” and “Oriental” Orthodox is the characterisation of Oriental teachers as heretics in the liturgical texts of the Byzantine Rite. The mere suggestion of liturgical revision to reflect the agreement that multiple theological vocabularies are legitimate and therefore theologians associated with them should not be anathematized or deprecated has been met with fierce opposition from some Eastern Orthodox. This paper considers what might actually be involved in such a revision, taking as an example the texts for the commemoration of the Council of Chalcedon. It suggests that the extent of necessary revision would be far less than is perhaps feared.
