Good and upright is the LORD: therefore will he teach sinners in the way.
Yes, that's the word I need. Immediacy.
I am not speaking of God's immanence. Insofar as God is immanent, He is manifest in all creation. Paul said, "In Him we live and move and have our being." (Pantheism takes this true teaching and twists it into worship of the creation rather than the Creator. It amounts to "holding the truth in unrighteousness.")
I believe Psalm 25 teaches me that God is my primary teacher. That is, He primarily teaches me without and apart from any human instrumentality. Or again, He teaches me without the aid of the church's teachers. Not only so, but no passage of Scripture contradicts the idea.
Certainly Christ gave His churches teachers, Eph. 4:11. However Paul described the ministry of a teacher in I Thessalonians 3:10, "Night and day praying exceedingly that we might see your face, and might perfect that which is lacking in your faith." A teacher in the church does not do it all, he is given to perfect (the verb, not the noun, accent on second syllable), or complete, that which is lacking in our faith. Of course we need more of this teaching when we are new believers, less as we grow to maturity in Christ. (But mostly what we need to do as new believers is...read the Bible.)
But the fact that Christ gave the churches teachers in no way disparages the truth that God alone is my primary teacher. In the present age Jesus says it is the Holy Spirit who is The Teacher, see John 14-17. But these two are the same thing. That of course is simply consistent with the doctrine of the Trinity.
Taken to heart, this truth changes everything about how we assemble on the Lord's day. It changes our meetings back to something resembling Romans 12 and I Corinthians 14. It changes the pastorate back to something resembling I Peter 5.
It is said that form follows function. If we recognize the Spirit in His teaching office, it changes the way we meet on the first day of the week. Then, the Spirit is sovereign, and the Word itself rather than teaching is primary, with the various speaking gifts complementing and augmenting rather than characterizing the ministry of the Word.
Paul ordered that his epistles be read in the churches. Simply read. And in Hebrews 13 we are commanded to remember them that have the rule (it simply means leadership and not Gentile-style authority) over us, "who have spoken unto (us) the word of God." Why? Only the Word of God is living and active, able to divide joint and marrow, soul and spirit.
It seems to me, then, that a primary ministry of the Word in the churches is...the Word itself.
Good teachers are wonderful and beneficial for the churches. I have learned much from good teachers. But I can only learn from them insofar as the Spirit has taught me directly from the Word. Then, when a teacher teaches me something good, it resonates with me because I know it squares with the written Word. I will not remember his teaching except insofar as it gives me something to hang my hat on in the Word, that is, chapter and verse. Thus Paul wrote, "My speech and my preaching was not with enticing words of man's wisdom but in demonstration of the Spirit and of power: that your faith should not stand in the wisdom of men, but in the power of God." I Cor. 2:4-5. I do not believe there is anything either mystical or subjective taught here. I think he was teaching that he used the actual words of what became the New Testament canon when he taught. In other words, it is likely that Paul taught exactly as is recorded in his letters! Where "the sermon" constitutes commentary on Paul's teaching, Paul's "commentary" was simply his epistles. For all we know he may have frequently read his letters in the churches. (However he also conversed with the people during his teaching. In Acts 20:7 where in the KJV it says "he preached unto them," the Greek word is dialogos, which means to converse.)
I fully understand that teaching is commentary (it is conventionally called "exposition," though there is no proof in the New Testament that this is the way Jesus or His apostles expounded the Scriptures) on the New Testament teachings. What I do not understand is why the ministry of the Word in the churches should necessarily and invariably take the form of sermon-teaching. This tradition in the churches ignores, 1) the other speaking gifts found in Romans 12, 2) provision for the use of the other speaking gifts in the assembly, 3) the efficacy of the pure, undefiled, unvarnished Word to minister to the saints gathered together, and 4) the sovereignty of the Teacher in the assembly.
Of course the Holy Spirit works through the teacher in addition to all the other brethren. But what is the main thing? It is the Spirit's work. That is, God is my teacher, and God is our teacher in the assembly as well. He is not limited to a single human instrument. Or, at least, that is not His will for the assemblies.
