If so, we are back to the Dark Ages when the Bible was hidden in dark aisles of church libraries.
Expository teaching is actually a redundant term. For what is expounding but explaining? And what is explaining but teaching? And what is teaching but explaining? But "expository teaching" isn't redundant in the way the seminarians use the term. For them, all the teachings of Scripture require expounding. Everything.
In Greek mythology Procrustes cut people up or stretched them in order to fit his iron bed. A "Procrustean solution" in Christian teaching is to make every text fit the sermon form, i.e., an introduction, three parts, a conclusion, citing of Greek and Hebrew words, and seminary or ecclesiastical lore.
If one reads the Sermon on the mount he does not find a shred of the sermon form. This does not mean the sermon form is unbiblical. It only means it has no basis in Scripture.
Expository teaching, as we know it, does not consist in simply explaining the Word. Rather, it is an institution in which one man explains the Scriptures for forty minutes every Sunday morning to the exclusion of all the other speaking gifts. Every Sunday morning until the Lord returns.
With these things in mind let us look at what the New Testament teaches and indicates. Make no mistake, Romans 12:3-8 is the template.
The leaders in the churches "spoke unto you the word of God," Heb. 13:7. In that the Word of God is living and active, this explains the power of the leaders speaking the Word to their flocks.
Believers must assemble in order to exhort and admonish one another to do the Lord's will. Exhortation is indisputably the most practical of speaking ministries, and many in the churches have an ability to exhort. Paul wrote the church at Rome, "ye also are...able also to admonish one another," Rom. 15:14. This assumes that the members of the church actually know one another–their treasure, their needs, their hopes, their fears, their frailties–and therefore are thoroughly equipped to minister to each other.
As occasion warrants, teachers will speak at length in order to "perfect that which is lacking in your faith," I Thess. 3:10. Teachers do not "do it all," but they supply what is lacking. It is assumed that God's children will, first and foremost, read the Scriptures themselves, in reliance on the Spirit of God as their Teacher. Teachers are given to perfect, and not to do it all.
George Müller demonstrated the role of teacher as is recorded in the book on his life by A.T. Pierson. You will notice that after accomplishing his teaching, he assumed a place of equality with the brethren, and not theoretical equality but actual equality. (I like to say that Müller, Groves, Chapman, Lang, Broadbent, et al., were the truly great theologians of the 19th and early 20th century Brethren, whereas those commonly called great theologians among the Brethren were for the most part ignorant of that branch of theology so deprecated by Christians–ecclesiology–that branch of doctrine which concerns the actual rather than theoretical Headship of Christ over His church.)
In addition to the speaking ministries there is prayer, fellowship (actual conversation among the men during the meeting, perhaps?), hymn singing, the contribution, and the breaking of bread. What is missing from this arrangement? Nothing.
