We desire only to ascertain the truth; nothing but the truth will endure; and the ascertainment of the truth and the proclamation of the truth in any given case, or upon any subject, will do no harm to the work of the Lord which is itself truth. Nor need we be surprised if now and then we find our predecessors, many of whom bear honored names and deserve our respect and gratitude for what they achieved in making clear the truth, as they conceived it to be—we need not be surprised if we sometimes find them mistaken in their conceptions and deductions; just as the generations who succeed us in unfolding in a larger way some of the yet unlearned truths of the Gospel, will find that we have had some misconceptions and made some wrong deductions in our day and time. . . .
The generation which preceded us did not exhaust by their knowledge all the truth, so that nothing was left for us in its unfolding; no, not even in respect of the Book of Mormon; any more than we shall exhaust all discovery in relation to that book and leave nothing for the generation following us to
develop. All which is submitted, especially to the membership of the Church, that they may be prepared to find and receive new truths both in the Book of Mormon itself and about it; and
that they may also rejoice in the fact that knowledge of truth is inexhaustible, and will forever go on developing.
