I was talking to a friend recently about the seemingly new Lutheran practice of inserting a "prayer of thanksgiving" between the Sanctus and the Our Father (or between the Sanctus and the Words of Institution), as can be seen, for example, in Lutheran Worship (LCMS, 1982), Lutheran Service Book (LCMS, 2006), and the brand new Christian Worship Supplement (WELS, 2008). My friend expressed his objections to this, seeing it as an ill-advised modern ecumenical concession to those who insist that a prayer at this point in the Liturgy is a necessity. I pointed out in response that the liturgical tradition of American Lutheranism included such a usage long before the advent of the modern "Liturgical Movement" with its various Dixian demands, and that another way of interpreting the appearance of such prayers in modern hymnals is to see it as a restoration of something that was previously used by American Lutherans within the memory of many who are alive today.
The Evangelical Lutheran Hymnal was published in 1908 by the Lutheran Book Concern (Columbus, Ohio), by order of the First English District of the Joint Synod of Ohio and Other States. The second part of "The Order of Morning Service," entitled The Holy Communion, includes the Preface, the Proper Preface, the Sanctus, the Exhortation, the Consecration, the Agnus Dei, the Pax, the Distribution, the Nunc Dimittis, the Thanksgiving, the Post-Communion Collect, the Benedicamus, and the Benediction.
Below you'll find the texts that appear under the heading "The Consecration," from pp. 21-22 of the 1908 Evangelical Lutheran Hymnal. You'll notice, by the way, that there is also a prayer following the Words of Institution. But the Words of Institution themselves are not embedded within a prayer. Luther D. Reed, on p. 351 of The Lutheran Liturgy (1947 revised edition), says that these Ohio Synod sacramental prayers were taken from the 1879 Liturgy of the Evangelical Lutheran Church in Bavaria. This 1908 hymnal, with this order of service, was not supplanted in the Ohio Synod until its 1930 merger with the Iowa and Buffalo Synods, at which time the new American Lutheran Hymnal - which removed such prayers from the Liturgy - was published. It is very likely, however, that many former Ohio Synod congregations in the new American Lutheran Church continued to use the 1908 hymnal well into the middle part of the twentieth century.
My friend was unaware of all of this. With the thought that there may be others who have a similar liturgical interest, but who likewise are unfamiliar with this tradition, I am sharing the pertinent section from the Ohio Synod liturgy here.
GLORY be to Thee, O Lord Jesus Christ, Thou almighty and everlasting Son of the Father, that by the sacrifice of Thyself upon the cross, offered up once for all, Thou didst perfect them that are sanctified, and ordain, as a memorial and seal thereof, Thy Holy Supper, in which Thou givest us Thy body to eat, and Thy blood to drink, that being in Thee, even as Thou art in us, we may have eternal life, and be raised up at the last day. Most merciful and exalted Redeemer, we humbly confess that we are not worthy of the least of all the mercies, and of all the truth, which Thou hast shown unto us, and that, by reason of our sins, we are too impure and weak worthily to receive Thy saving gifts. Sanctify us, therefore, we beseech Thee, in our bodies and souls, by Thy Holy Spirit, and thus fit and prepare us to come to Thy Supper, to the glory of Thy grace, and to our own eternal good. And in whatsoever, through weakness, we do fail and come short, in true repentance and sorrow on account of our sins, in living faith and trust in Thy merits, and in an earnest purpose to amend our sinful lives, do Thou graciously supply and grant, out of the fulness of the merits of Thy bitter sufferings and death; to the end that we, who even in this present world desire to enjoy Thee, our only comfort and, Savior, in the Holy Sacrament, may at last see Thee face to face in Thy heavenly kingdom, and dwell with Thee, and with all Thy saints, for ever and ever. Amen.
OUR FATHER, Who art in heaven; Hallowed be Thy Name; Thy kingdom come; Thy will be done on earth, as it is in heaven; Give us this day our daily bread; And forgive us our trespasses, as we forgive those who trespass against us; And lead us not into temptation; But deliver us from evil; For Thine is the kingdom, and the power, and the glory, for ever and over. Amen.
OUR LORD Jesus Christ, in the night in which He was betrayed, took bread; and when He had given thanks, He brake and gave it to His disciples, saying, Take, eat; this is My body, which is given for you; this do in remembrance of Me.
AFTER the same manner, also, He took the cup, when He had supped, and when He had given thanks, He gave it to them, saying, Drink ye all of it; this cup is the New Testament in My blood, which is shed for you, and for many, for the remission of sins; this do, as oft as ye drink it, in remembrance of Me.
PRAISE, and honor, and glory, be unto Thee, O Christ! The bread which we bless is the communion of Thy holy body, and the cup which we bless is the communion of Thy holy blood. O Thou everlasting Son of the Father, sanctify us by Thy Holy Spirit, and make us worthy partakers of Thy sacred body and blood, that we may be cleansed from sin and made one with all the members of Thy Church in heaven and on earth. Lord Jesus! Thou hast bought us: to Thee will we live, to Thee will we die, and Thine will we be forever. Amen.
