as the Smalcald Articles express this mystery: "Of the Sacrament of the Altar, we hold that the bread and wine in the Supper are Christ’s true body and blood.
My Catholic teachers taught me that “consubstantiation” was yet another of the theories invented by the medieval, western, Catholic Scholastics. I forget the name of that man most associated with it…
Although I understand Luther used that term twice in his life, he clearly did not mean it in the sense of Catholic Schlasticism.
As I understand it (and yup, I’m a fairly new convert to Lutheranism), Lutheranism simply embraces Real Presense. Passionately and literally. As I like to put it, in the Eucharistic texts, the meaning of is is is (pardon the grammar, lol). I’ve discovered that Lutherans embrace all this as real, physical, literal - and significant - as do Catholics.
The “difference” is that while Lutherans regard the bread and wine as totally moot to anything at all (CHRIST IS PRESENT - by obsess over that dry waffer or the wine the ladies got on sale, lol?), nor it is dogmatically DENIED. Paul speaks of bread and wine more often AFTER the Consecration than before it. There’s no TEXTUAL or theological reason to “explain away” what the text clearly says with a “half literal/ half symobolic” interpretation (as Zwingli did). But again, all this is simply moot and irrelevant. Who cares about the bread and wine? CHRIST is here! CHRIST is the focus. CHRIST is the object of faith. CHRIST is the blessing and Blesser.
Lutherans simply affirm the miracle, the mystery. Lutherans simply affirm the inscripturated words of God in the text - all of them. Literally. Fully. Lutherans feel no need to tell God HOW He fulfills His promises or grants His blessings. There’s just no need to do that. Lutherans are simply more comfortable with mystery, with leaving things as God does in His Word.
I agree that 'Sacramental Union." As I understand this, it’s NOT dogma but it was a common thought among the Lutheran Fathers. It is the mystery that His Body and Blood are in a “union” (of some nature unknown to us - it’s not necessary that it is known to us) with the bread and wine. Luther’s words in the Small Catechism of “in, with, and under” (which I find odd, btw) are - I think - his way of conveying this to children (the Catechism was written for such). Christ is THERE. And there is some mysterious “connection” of such to bread and wine. This DOES seem to be in conflict with the dogma of Transubstantiation that The Catholic Church would adopt just after Luther’s death - that concerns the word “convert” in the Eucharistic texts (which, of course, doesn’t exist in any of them). Luther’s concern was not to deny or explain away what the texts say, or to impose alchemy or Aristotle’s theory of accidents. I think he simply desired to affirm the REALITY of Christ and His literal, physical, real presence - without saying anything about the bread and wine.
I hope that helps a bit, anyway.
