"And I give unto you a commandment that you shall teach one another the doctrine of the kingdom; teach ye diligently and my grace shall attend you, that you may be instructed more perfectly in theory, in principle, in doctrine, in the law of the gospel, in all things that pertain unto the kingdom of God, that are expedient for you to understand. Of things both in heaven and in the earth, and under the earth; things which have been, things which are, things which must shortly come to pass; things which are at home, things which are abroad; the wars and the perplexities of the nations, and the judgments which are on the land, and a knowledge also of countries and of kingdoms. That ye may be prepared in all things when I shall send you again to magnify the calling whereunto I have called you, and the mission with which I have commissioned you. * * * Therefore, verily, I say unto you, my friends, call your solemn assembly, as I have commanded you; and as all have not faith, seek, ye diligently and teach one another words of wisdom; yea, seek ye out of the best books words of wisdom; seek learning even by study, and also by faith." (Doc. & Cov. Sec. 88:77, 78, 80 and 117, 118.) The instructions then given to the Elders of the Church are still applicable to men engaged in the same ministry, and charged with like responsibility. Elsewhere I have said, on the foregoing passage from the Doctrine and Covenants: "I think I may safely challenge any one to point out a broader field of knowledge than is here indicated. It includes all spiritual truth, all scientific truth, all secular knowledge--knowledge of the past, of the present, of the future; of the heavens, and of the earth. A knowledge of all countries, their geography, languages, history, customs, laws and governments--everything in fact that pertains to them. There is nothing in the heights above or the depths below that is not included in this field of knowledge into which the commandment of God directs his servants to enter. I may claim for it that it includes the whole realm of man's intellectual activities. And the doctrine that whatever principles of intelligence man attains unto in this life will rise with him in the morning of the resurrection--this doctrine that nothing acquired in respect of knowledge is ever lost, must forever form the most powerful incentive to intellectual effort that possibly can be conjured up by the wit of man. So that, referring to the acquirement of knowledge, and intellectual development, Mormonism at once both indicates the broadest field and furnishes the grandest incentive to intellectual effort." ("The Mormon Point of View in Education," Improvement Era, Vol. II, p. 119.) Commenting once upon the above passages from the Doctrine and Covenants, the writer remarked:
