Haute Église
The Roman and Eastern Catholic Churches, Eastern Orthodox Church, the Oriental Orthodox churches, the Assyrian and Ancient Churches of the East, and Lutherans, together with High church Anglicans, know this as the real presence of Christ in the Eucharist. The Catholic Church uses the term "transubstantiation" to describe the change of the bread and wine into the body and blood of Christ. The Eastern Orthodox Churches used the same term to describe the change, as in the decrees of the 1672 Synod of Jerusalem, and the "Catechism of St. Philaret (Drozdov) of Moscow".
