Citations, please. One point of clarification: nobody teaches a physical presence - not the Roman Catholics, not the Eastern Orthodox, not the Lutherans - and nobody denies a real presence, not even the Zwinglians (who recognize the presence of Christ in the believer, and insofar as a thing present in the mind is still "real" insofar as it is independent of other minds, has its source outside the mind, and is itself a source of action). The wording of some of the old Confessions can be confusing as they often seem to speak of a "physical" or "corporeal" presence, either to describe an opponents position polemically or their own position constructively. Such imprecision of language can be set aside today. All sides of the descendants of those parties know and openly acknowledge today that if one takes the Eucharistic elements and puts them under a microscope, all one will observe are molecules of bread and wine, bacteria, etc. The mass and weight of the elements don't double or disappear post-consecration. The real, Confessional alternatives are between an objective presence on the one hand (i.e., Christ is present in the sacrament irrespective of our faith), and a subjective presence on the other (i.e., Christ is present in the souls of those who have faith). For the former, the objective presence, which is not limited to the souls of believers but includes the Eucharistic elements as well, is supernatural, not "physical".
