Gerhard Loci “De coena s.”, 151 cited by Pieper III.367, n. 110 : “...the Son of God Himself repeats the words, uttered once upon a time, through the mouth of the minister and through them hallows, consecrates, and blesses the bread and wine to be the medium of distributing His body and blood.”
“Such a consecration petition [epiclesis] is an appropriate sign indication that the Lord Himself is and remains the One who acts in Holy Communion. In that way it serves the honor of Christ” (Brunner 302).
See Brunner p. 290ff and note 328 for texts from Ambrose, Thomas, et al.
“Luther is the finisher of this Occidental doctrine, which dates back to Augustine, the doctrine of the exclusive power of the words of Christ in the administration of the sacrament” (Brunner 293).
Luther, Against the Private Mass, “prolatis verbis (hoc est corpus meum) fieret ex pane corpus Christi.”
"For as soon as Christ says: 'This is my Body,' his body is present through the Word and the power of the Holy Spirit. If the Word is not there, it is mere bread; but as soon as the words are added they bring with them that of which they speak." AE 36:341
Ambrose, De Sacramentis, iv: “The consecration is accomplished by the words and expressions of the Lord Jesus. Because, by all the other words spoken praise is rendered to God, prayer is put up for the people, for kings, and others; but when the time comes for perfecting the sacrament, the priest no longer uses his own words, but the words of Christ. Therefore, it is Christ’s words that perfect this sacrament.”
If Christ is truly present in the Bread, why should He not be treated with the utmost respect and even be adored?" Joachim, a friend, added: "We saw how Luther bowed low at the Elevation with great devotion and reverently worshiped Christ. (Mathesius, Table Talk, Leipzig, 1903, 341)
FC SD VII, 75-82 outlines the Lutheran doctrine of consecration and instructs us to say the words over “the bread and chalice.”
“The presiding minister faces the elements on the altar during the consecration” LSB rubric; same as in The Lutheran Liturgy, p. 23.
