As I explained in the other thread, the popular apologetic copout called the "Official Doctrine" distinction (as opposed to "unofficial" doctrine) was a fabrication by the apologists, and eventually the Church just went along with it.
Don't believe me? Then go ahead and show me where "the Church" emphatically states there is a distinction! Before 1982 there was virtually no talk about "official" doctrine. I searched my Gospel Link software that contains literally hundreds of Church published books, magazines, journals, and all other forms of Church literature, and the two words "official doctrine" do not appear together before 1977. In this case someone mailed the Church with a question:
Should that which is written in Church publications and lesson manuals be taken as official doctrine?
Dean L. Larsen, “I Have a Question,” Ensign, Aug. 1977, 38
Elder Dean L. Larsen of the First Quorum of the Seventy and Managing Director of Curriculum Resources Church publications fall into four general categories: (1) materials related to the curriculum, such as lesson manuals, teachers’ supplements, and student materials; (2) magazines; (3) administrative documents, such as handbooks, leadership training materials, organizational guidelines and bulletins, etc.; and (4) missionary discussions, tracts, and support materials. All of the materials within these four categories are prepared under the direction of some officially recognized Church agency, and they are reviewed and cleared by the Church Correlation Review committees before they are published and issued to the Church... the content of the approved Church publications identified above does not claim the same endorsement that the standard works receive, nonetheless they are prepared with great care and are carefully screened before they are published. Writers of curriculum materials must be cleared by the First Presidency and the Council of the Twelve. Their product is reviewed closely by the heads of the organizations that are responsible for their implementation. Correlation Review committees check carefully for doctrinal accuracy and for harmony with established Church policies and procedures.
The General Handbook of Instructions is not only reviewed by Correlation, but also receives a close auditing from each individual member of the First Presidency and the Twelve.
Church magazines draw their content from a wide range of authors and contributors, in addition to those who serve as professional staff members. Those items that are published in the magazines receive not only the scrutiny and judgment of the editing staffs, but are also subject to clearance by the Correlation Review committees. Committee members are called as a result of their expertise in such areas as Church doctrine, Church history, and Church administration, and serve three different age groups: adult, youth, and children.
Much care is exercised to make certain that the official publications of the Church carry messages that are sound in doctrine and fully in harmony with currently approved policies and procedures. A constant effort is maintained to upgrade and correct the content of these materials so that they can merit the confidence and approval of Church leaders and the general membership.
Notice that the author doesn't directly answer the question, probably because the concept of "official doctrine" is foreign to him, same as it was every other Mormon on the planet. So he responds by assuring the person that these materials were screened by an "officially" recognized Church agency. The entire response is clearly suggesting that these materials are perfectly reliable. So with this level of screening going on, how in the bejeezus could false doctrine or untruths slip through the cracks? Of course it is "official."
Five years later someone mails in another question about "official doctrine":
Is President Lorenzo Snow’s oft-repeated statement—“As man now is, God once was; as God now is, man may be”—accepted as official doctrine by the Church?
Gerald N. Lund, “I Have a Question,” Ensign, Feb. 1982, 39–40
Gerald N. Lund, Teacher Support Consultant for the Church Education System. To my knowledge there has been no “official” pronouncement by the First Presidency declaring that President Snow’s couplet is to be accepted as doctrine. But that is not a valid criteria for determining whether or not it is doctrine.
Generally, the First Presidency issues official doctrinal declarations when there is a general misunderstanding of the doctrine on the part of many people. Therefore, the Church teaches many principles which are accepted as doctrines but which the First Presidency has seen no need to declare in an official pronouncement. This particular doctrine has been taught not only by Lorenzo Snow, fifth President of the Church, but also by others of the Brethren before and since that time...
[After citing a half dozen instances where past Prophets and Apostles had cited this as doctrine, he goes on to say...]
Numerous sources could be cited, but one should suffice to show that this doctrine is accepted and taught by the Brethren. In an address in 1971, President Joseph Fielding Smith, then serving as President of the Quorum of the Twelve Apostles, said:
“I think I can pay no greater tribute to [President Lorenzo Snow and Elder Erastus Snow] than to preach again that glorious doctrine which they taught and which was one of the favorite themes, particularly of President Lorenzo Snow. . . . (emphasis his!)
“This is a doctrine which delighted President Snow, as it does all of us(emphasis his!). Early in his ministry he received by direct, personal revelation the knowledge that (in the Prophet Joseph Smith’s language), ‘God himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens,’ and that men ‘have got to learn how to be Gods . . . the same as all Gods have done before.’
“After this doctrine had been taught by the Prophet, President Snow felt free to teach it also, and he summarized it in one of the best known couplets in the Church. . . .
“This same doctrine has of course been known to the prophets of all the ages, and President Snow wrote an excellent poetic summary of it.” (emphasis his!)(Address on Snow Day, given at Snow College, 14 May 1971, pp. 1, 3–4; italics added.)
It is clear that the teaching of President Lorenzo Snow is both acceptable and accepted doctrine in the Church today.
Of course years later Gordon B. Hinckley turns all of this on its head during the Time Magazine and Larry King interviews.
