De unione ecclesiarum: Sententia synodalis

"Below is presented a translation of a formal declaration made by a synod held in Constantinople on Friday, May 3rd, 1280 under the presidency of Patriarch John Bekkos. The synod dealt with the case of the referendarius Michael Eskammatismenos, who had erased the word ἐκ (“from”) from a theologically-significant passage of St. Gregory of Nyssa’s On the Lord’s Prayer."
