Now, I come reluctantly to where we Confessional Lutherans and the Catholics part ways in our understanding of Holy Communion and why, without direct and true reconciliation between our Churches, we can never truly share the same Table:
*
108] 1. The papistic transubstantiation, when it is taught that the consecrated or blessed bread and wine in the Holy Supper lose entirely their substance and essence, and are changed into the substance of the body and blood of Christ in such a way that only the mere form of bread and wine is left, or accidentia sine subiecto (the accidents without the object); under which form of the bread, which nevertheless is bread no longer, but according to their assertion has lost its natural essence, the body of Christ is present even apart from the administration of the Holy Supper, when the bread is enclosed in the pyx or is carried about for display and adoration. For nothing can be a sacrament without God’s command and the appointed use for which it is instituted in God’s Word, as was shown above.
112] Accordingly, with heart and mouth we reject and condemn as false, erroneous, and misleading all Sacramentarian opiniones (opinions) and doctrines which are not in accordance with, but contrary and opposed to, the doctrine above presented and founded upon God’s Word:
113] 1. As when they assert that the words of institution are not to be understood simply in their proper signification, as they read, of the true, essential presence of the body and blood of Christ in the Supper, but are to be wrested, by means of tropi (tropes) or figurative interpretations, to another new, strange sense. We hereby reject all such Sacramentarian opiniones (opinions) and self-contradictory notions [of which some even conflict with each other], however manifold and various they may be.
114] 2. Also, that the oral participation of the body and blood of Christ in the Supper is denied [by the Sacramentarians], and it is taught, on the contrary, that the body of Christ in the Supper is partaken of only spiritually by faith, so that in the Supper our mouth receives only bread and wine.
115] 3. Likewise, also, when it is taught that bread and wine in the Supper should be regarded as nothing more than tokens by which Christians are to recognize one another; or,
118] 7. Or that the body and blood of Christ cannot be received and partaken of otherwise than only spiritually, by faith.
119] 8. Likewise, when it is taught that because of His ascension into heaven Christ is so enclosed and circumscribed with His body in a definite place in heaven that with the same [His body] He cannot or will not be truly present with us in the Supper, which is celebrated according to the institution of Christ upon earth, but that He is as far and remote from it as heaven and earth are from one another, as some Sacramentarians have wilfully and wickedly falsified the text, Acts 3:21; oportet Christum coelum accipere, that is, Christ must occupy heaven, for the confirmation of their error, and instead thereof have rendered it: oportet Christum coelo capi, that is, Christ must be received or be circumscribed and enclosed by heaven or in heaven, in such a manner that in His human nature He can or will in no way be with us upon earth.
120] 9. Likewise, that Christ has not promised the true, essential presence of His body and blood in His Supper, and that He neither can nor will afford it, because the nature and property of His assumed human nature could not suffer or admit of it.
121] 10. Likewise, when it is taught that not only the Word and omnipotence of Christ, but faith, renders the body of Christ present in the Supper; on this account the words of institution in the administration of the Supper are omitted by some. For although the papistic consecration is justly rebuked and rejected, in which the power to produce a sacrament is ascribed to the speaking as the work of the priest, yet the words of institution can or should in no way be omitted in the administration of the Supper, as is shown in the preceding declaration.
122] 11. Likewise, that believers are not to seek, by reason of the words of Christ’s institution, the body of Christ with the bread and wine of the Supper, but are directed with their faith away from the bread of the Supper to heaven, to the place where the Lord Christ is with His body, that they should become partakers of it there.
123] 12. We reject also the teaching that unbelieving and impenitent, wicked Christians, who only bear the name of Christ, but do not have the right, true, living, and saving faith, receive in the Supper not the body and blood of Christ, but only bread and wine. And since there are only two kinds of guests found at this heavenly meal, the worthy and the unworthy, we reject also the distinction made among the unworthy [made by some who assert] that the godless Epicureans and scoffers at God’s Word, who are in the external fellowship of the Church, when using the Holy Supper, do not receive the body and blood of Christ for condemnation, but only bread and wine.
124] 13. So, too, the teaching that worthiness consists not only in true faith, but in man’s own preparation.
125] 14. Likewise, the teaching that even true believers, who have and keep a right, true, living faith, and yet lack the said sufficient preparation of their own, could, just as the unworthy guests, receive this Sacrament to condemnation.
126] 15. Likewise, when it is taught that the elements or the visible species or forms of the consecrated bread and wine must be adored. However, no one, unless he be an Arian heretic, can and will deny that Christ Himself, true God and man, who is truly and essentially present in the Supper, should be adored in spirit and in truth in the true use of the same, as also in all other places, especially where His congregation is assembled.
