Likewise also, if any should wish to unsettle in any manner whatever the things done concerning each case in the holy synod at Ephesus, the holy synod has decreed that, if they are bishops or clerics, they fall utterly from their own rank; and if laymen, that they be out of communion.
Ὁμοίως δὲ καὶ εἴ τινες βουληθεῖεν, τὰ περὶ ἑκάστου πεπραγμένα ἐν τῇ ἁγίᾳ συνόδῳ, τῇ ἐν Ἐφέσῳ, οἱῳδήποτε τρόπῳ παρασαλεύειν, ἡ ἁγία σύνοδος ὥρισεν, εἰ μὲν ἐπίσκοποι εἶεν, ἢ κληρικοί, τοῦ οἰκείου παντελῶς ἀποπίπτειν βαθμοῦ· εἰ δὲ λαϊκοί, ἀκοινωνήτους ὑπάρχειν.
