The Book of Concord and the Lord’s Supper
The Book of Concord states the Lord’s Supper is not physical, earthly nor Capernaitic. I do not recall where it states it is heavenly, but recall reading that. I have the Concordia, The Lutheran Confessions...A Reader’s Edition 2005. Would appreciate a response to my question. Thank you.
You might be thinking of this: “105] But when Dr. Luther or we employ this word spiritual in regard to this matter, we understand by it the spiritual, supernatural, heavenly mode, according to which Christ is present in the Holy Supper, working not only consolation and life in the believing, but also condemnation in the unbelieving; whereby we reject the Capernaitic thoughts of the gross [and] carnal presence which is ascribed to and forced upon our churches by the Sacramentarians against our manifold public protestations. In this sense we also say [wish the word spiritually to be understood when we say] that in the Holy Supper the body and blood of Christ are spiritually received, eaten, and drunk, although this participation occurs with the mouth, while the mode is spiritual.
“106] Thus our faith in this article concerning the true presence of the body and blood of Christ in the Holy Supper is based upon the truth and omnipotence of the true, almighty God, our Lord and Savior Jesus Christ. These foundations are strong and firm enough to strengthen and establish our faith in all temptations concerning this article, and, on the contrary, to overthrow and refute all the counter-arguments and objections of the Sacramentarians, however agreeable and plausible they may be to our reason; and upon them a Christian heart also can securely and firmly rest and rely.” [Concordia Triglotta. The Formula of Concord. Thorough Declaration. VII. Of the Holy Supper]
That section is in the context of Luther writing about the three modes of Jesus’ body being omnipresent: bodily, spiritual and heavenly.
