When God speaks to the people, he does it in a manner to suit their circumstances and capacities. He spoke to the children of Jacob through Moses, as a blind, stiff-necked people, and when Jesus and his Apostles came they talked with the Jews as a benighted, wicked, selfish people. They would not receive the Gospel, though presented to them by the Son of God in all its righteousness, beauty and glory. Should the Lord Almighty send an angel to re-write the Bible, it would in many places be very different from what it now is. And I will even venture to say that if the Book of Mormon were now to be re-written, in many instances it would materially differ from the present translation. According as people are willing to receive the things of God, so the heavens send forth their blessings. If the people are stiff-necked, the Lord can tell them but little.

I am more afraid that this people have so much confidence in their leaders that they will not inqure for themselves of God whether they are led by him. I am fearful they settle down in a state of blind self-security, trusting their eternal destiny in the hands of their leaders with a reckless confidence that in itself would thwart the purposes of God in their salvation, and weaken that influence they could give to their leaders, did they know for themselves, by the revelations of Jesus, that they are led in the right way. Let every man and woman know, by the whispering of the Spirit of God to themselves, whether their leaders are walking in the path the Lord dictates, or not. (Brigham Young, Journal of Discourse 9:150)

Discussing the Endowment:

"Bro[ther] Joseph [Smith] turned to me [Brigham Young] and said: “Brother Brigham this is not arranged right, but we have done the best we could under the circumstances in which we are placed, and I wish you to take this mat[t]er in hand and organize and systematize all these ceremonies with the signs, tokens, penalties and key words.” I did so and each time I got something more; so that when we went through the Temple at Nauvoo, I understood and knew how to place them there. We had our ceremonies pretty correct."

"The being that has comparatively no strong passion to overcome ought constantly to walk in the vale of humility, rather than boast of his righteousness over his brother... Those who have not strong passions to contend with, day by day, and year by year, should walk in the vale of humiliation; and if brethren and sisters are overtaken in fault, your hearts should be filled with kindness—with brotherly, angelic feeling—to overlook their faults as far as possible."

"There is one principle I wish to urge upon the Saints in a way that it may remain with them—that is, to understand men and women as they are, and not understand them as you are."

Brigham Young

"I want to say to my friends that we believe in all good. If you can find a truth in heaven, earth or hell, it belongs to our doctrine. We believe it; it is ours; we claim it...
[The gospel] embraces all morality, all virtue, all light, all intelligence, all greatness, and all goodness."

Brigham Young

Teachings of the Presidents: Brigham Young (Chapter 2)

"How gladly would we understand every principle pertaining to science and art, and become thoroughly acquainted with every intricate operation of nature, and with all the chemical changes that are constantly going on around us! How delightful this would be, and what a boundless field of truth and power is open for us to explore! We are only just approaching the shores of the vast ocean of information that pertains to this physical world, to say nothing of that which pertains to the heavens, to angels and celestial beings, to the place of their habitation, to the manner of their life, and their progress to still higher degrees of perfection."

Do you think that we are always going to remain the same size? I am not a stereotyped Latter-day Saint, and do not believe in the doctrine... Away with stereo-typed "Mormons."
