The theologians Brad Harper and Paul Louis Metzger state that: The Greek term metousiosis () is sometimes used by Eastern Orthodox Christians to describe the change since this term "is not bound up with the scholastic theory of substance and accidents", but it does not have official status as "a dogma of the Orthodox Communion. Similarly, Coptic Orthodox Christians "are fearful of using philosophical terms concerning the real presence of Christ in the Eucharist, preferring uncritical appeals to biblical passages like 1 Cor. 10.16; 11.23–29 or the discourse in John 6.26–58."
