To take a stab at real presence for sake of the Lutherans: Christ’s humanity is not ubiquitous, but his divinity being everywhere present, in his Holy Spirit (who delivers the Word), does make true his offer of his human body and blood – personally – to all who take the bread and wine with faith; and so those enjoy his humanity’s real presence who meet it by the power of the Holy Ghost.
Is this truly something the Lutherans cannot accept? For so they will have both their ubiquity and their communicatio idiomatum, albeit by no other means than the Spirit of Christ. Although surely better minds have tried and failed, I cannot see but that this already gives all that is of any moment. For what does it matter that a genus maiestaticum is affirmed, if it be confessed that the humanity of Christ is present in every manner that evangelical piety would seek?
