The Purpose of the Eucharist lies not in the change of the bread and wine, but in the partaking of Christ, who has become our food, our life, the manifestation of the Church as the body of Christ. This is why the gifts themselves never became in the Orthodox East an object of special reverence, contemplation, and adoration, and likewise an object of special theological 'problematics': how, when, in what manner their change is accomplished.
