Unfortunately there are many within the LCMS who no longer believe the doctrine of the LCMS. The following, however, makes it clear what the honest members of the Synod believe. It is from this belief system that practice follows. Theology is practical!
The "What About?" documents on various subjects written by Dr. Al Barry, former president of the Lutheran Church Missouri Synod.
"Of the Holy Scriptures" -- Official statement of the LCMS in 1932; still carries authority within the synod. This conservative view of Scripture controls what the LCMS believes and practices.
"Women In the Church" contains all the relevant documents about women in the church and ministry. Written with an honest eye to God's Word as the final authority on faith and practice.

[Adopted 1932]
1. We teach that the Holy Scriptures differ from all other books in the world in that they are the Word of God. They are the Word of God because the holy men of God who wrote the Scriptures wrote only that which the Holy Ghost communicated to them by inspiration, 2 Tim. 3:16; 2 Pet. 1:21. We teach also that the verbal inspiration of the Scriptures is not a so-called "theological deduction," but that it is taught by direct statements of the Scriptures, 2 Tim. 3:16, John 10:35, Rom. 3:2; 1 Cor. 2:13. Since the Holy Scriptures are the Word of God, it goes without saying that they contain no errors or contradictions, but that they are in all their parts and words the infallible truth, also in those parts which treat of historical, geographical, and other secular matters, John 10:35.
2. We furthermore teach regarding the Holy Scriptures that they are given by God to the Christian Church for the foundation of faith, Eph. 2:20. Hence the Holy Scriptures are the sole source from which all doctrines proclaimed in the Christian Church must be taken and therefore, too, the sole rule and norm by which all teachers and doctrines must be examined and judged. -- With the Confessions of our Church we teach also that the "rule of faith" (analogia fidei) according to which the Holy Scriptures are to be understood are the clear passages of the Scriptures themselves which set forth the individual doctrines. (Apology. Triglot, p. 441, Paragraph 60; Mueller, p. 684). The rule of faith is not the man-made so-called "totality of Scripture" ("Ganzes der Schrift").
3. We reject the doctrine which under the name of science has gained wide popularity in the Church of our day that Holy Scripture is not in all its parts the Word of God, but in part the Word of God and in part the word of man and hence does, or at least, might contain error. We reject this erroneous doctrine as horrible and blasphemous, since it flatly contradicts Christ and His holy apostles, set up men as judges over the Word of God, and thus overthrows the foundation of the Christian Church and its faith.

The document
on “The service of women in congregational and synodical
offices with guidelines for congregations [2005] is the most recent report about
LCMS theology and practice in regards to women. According to this report, women
should not be leading the worship service as that is a function of the pastoral
office.
