"…in the Eucharist, man participates in the glorified humanity of Christ, which is not the ‘essence of God,’ but a humanity still consubstantial to man and available to him as food and drink…for later Byzantine theologians, the Eucharist is Christ’s transfigured, life-giving, but still human, body, en-hypostasized in the Logos and penetrated with divine ‘energies.’ Characteristically, one never finds the category of ‘essence’ (ousia) used by Byzantine theologians in a Eucharistic context. They would consider a term like ‘transubstantiation’ (metousiosis) improper to designate the Eucharistic mystery, and generally use the concept of metabole, found in the canon of John Chrysostom, or such dynamic terms as** ‘trans-elementation’ (metastoicheiosis**) or ‘re-ordination’ (metarrhythmisis). - John Mayendorff, Byzantine Theology, 1974, pp. 203-204
