Thanks for your comments, Bogey. I have just a few criticisms.
As for the sick and shut ins our priest takes a small amount of the elements and delivers a short homily and blesses the elements there and communes the sick and the shut ins there so that nothing is left over. But the purpose of this is not because the blessing may wear off but because the desire is that the holy will not be profaned by being placed with the common.
If, as you said earlier, mingling consecrated elements with unconsecrated elements is avoided to prevent blessing the elements twice, why would Lutheran ministers bless the elements again a second time for the sick?
Furthermore, treating consecrated elements after the service has ended as “holy” does not prove that Lutherans on either a synodal or confessional level believe that the Real Presence endures after the service.
OK first off Luther cut the knot about transubstantiation. There is no formula taught about trans or con substantiation in my synod (which is not WELS/LCMS/ELCA btw) but that since Christ has spoken these elements to be His Body and Blood they therefore are. The Lord has spoken and thus it is so.
So do not mix teaching against transubstantiation (which Lutherans do not teach) with teachings about the actual presence (which Lutherans do teach). So what is being said in 107-108 in the FOC is that those elements in the pyx which have not been blessed on the Altar are not the Body and the Blood. That is what they mean when they are speaking of those elements being apart from the Sacrament. They don’t mean once they are carried out the Church the blessed elements cease to be the Body and Blood they mean that simply adding more elements to the blessed elements apart from the Sacrament does not automatically make those elements also blessed.
In other words it the words of institution spoken by Christ that makes the Sacrament the Sacrament not the mere presence of bread and wine. But no orthodox Lutheran that I know of (and again my Synod is small) would teach that once consecrated the elements lose their blessing or cease to be holy because they have left the building of the Church.
Let me clarify that I am not teaching that Lutherans deny the Real Presence during the service. That said, Lutherans teach a doctrine of “sacramental union” which is contrary to transubstantiation. Sacramental union, defined in the Formula of Concord, is the belief that the bread an wine are not transformed into the body and blood of Christ (as Catholics believe), but rather the body and blood of Christ are united sacramentally to the bread and wine, which do not lose the essence of bread and wine. The FOC teaches that Christ is substantially present but that it is in a “sacramental union” with the substance of bread and wine.
For the reason why, in addition to the expressions of Christ and St. Paul (the bread in the Supper is the body of Christ or the communion of the body of Christ), also the forms: under the bread, with the bread, in the bread [the body of Christ is present and offered], are employed, is that by means of them the papistical transubstantiation may be rejected and the sacramental union of the unchanged essence of the bread and of the body of Christ indicated; just as the expression, Verbum caro factum est, The Word was made flesh John 1:14 ], is repeated and explained by the equivalent expressions: The Word dwelt among us; likewise Col 2:9 ]: In Him dwelleth all the fulness of the Godhead bodily; likewise Acts 10:38 ]: God was with Him; likewise 2 Cor. 5:19 ]: God was in Christ, and the like; namely, that the divine essence is not changed into the human nature, but the two natures, unchanged, are personally united. [These phrases repeat and declare the expression of John, above mentioned, namely, that by the incarnation the divine essence is not changed into the human nature, but that the two natures without confusion are personally united.] Even as many eminent ancient teachers, Justin, Cyprian, Augustine, Leo, Gelasius, Chrysostom and others, use this simile concerning the words of Christ’s testament: This is My body, that just as in Christ two distinct, unchanged natures are inseparably united, so in the Holy Supper the two substances, the natural bread and the true natural body of Christ, are present together here upon earth in the appointed administration of the Sacrament.

This is why the Lutheran doctrine has been called “consubstantiation” or “impanation” by others, although Lutherans do not call it that. I agree with you that Lutherans do not deny the Real Presence in the sacrament.
I don’t think your reading of FOC 7.108 is correct. Remember that this passage is condemning Catholic (or “papistic”) doctrine. Catholics do not enclose unconsecrated bread in a pyx, nor do they carry unconsecrated bread about for display and adoration. Neither do Catholics believe that mingling unconsecrated bread with consecrated bread consecrated the unconsecrated bread or that bread becomes the Body of Christ by virtue of inhabiting a pyx or monstrance. Because this is a rejection of Catholic doctrine, it must be understood as a rejection of the Catholic belief that the Christ is present in the Eucharist apart from the administration of the Holy Supper, which the FOC seems to confine to a single service. Refer back to my first post where I have the full paragraph excerpted.
