**I really didn’t feel the need to proceed any further but since you require it
I don’t usually like to post long extracts, but I think it might be informative to answer the present assertion.
Sermon by Brigham Young (broader extract)
*I could give you a logical reason for all the transgressions in this world, for all that are committed in this probationary state, and especially for those committed by men.
There are sins that men commit for which they cannot receive forgiveness in this world, or in that which is to come, and if they had their eyes open to see their true condition, they would be perfectly willing to have their blood spilt upon the ground, that the smoke thereof might ascend to heaven as an offering for their sins; and the smoking incense would atone for their sins, whereas, if such is not the case, they will stick to them and remain upon them in the spirit world.*
To our understanding he is trying to get across the idea of a lack of understanding of the consequences of the persistent sins being committed by some in his charge. The line of thought being “If they really knew what they were doing, and understood the end result of their behaviour, they would be willing to do anything to prevent it”(paraphrase)
I know, when you hear my brethren telling about cutting people off from the earth, that you consider it is strong doctrine; but it is to save them, not to destroy them.
Trying to bring those in sin to an understanding of their predicament
*Of all the children of Israel that started to pass through the wilderness, none inherited the land which had been promised, except Caleb and Joshua, and what was the reason? It was because of their rebellion and wickedness; and because the Lord had promised Abraham that he would save his seed.
They had to travel to and fro to every point to the compass, and were wasted away, because God was determined to save their spirits. But they could not enter into His rest in the flesh, because of their transgressions, consequently He destroyed them in the wilderness.*
A description of the doctrine in ancient times
*I do know that there are sins committed, of such a nature that if the people did understand the doctrine of salvation, they would tremble because of their situation. And furthermore, I know that there are transgressors, who, if they knew themselves, and the only condition upon which they can obtain forgiveness, would beg of their brethren to shed their blood, that the smoke thereof might ascend to God as an offering to appease the wrath that is kindled against them, and that the law might have its course. I will say further; I have had men come to me and offer their lives to atone for their sins.*
**Again restating “If they only knew what they were doing they would tremble because of their situation”(paraphrase) **
*It is true that the blood of the Son of God was shed for sins through the fall and those committed by men, yet men can commit sins which it can never remit. As it was in ancient days, so it is in our day; and though the principles are taught publicly from this stand, still the people do not understand them; yet the law is precisely the same. There are sins that can be atoned for by an offering upon an altar, as in ancient days; and there are sins that the blood of a lamb, of a calf, or of turtle doves, cannot remit, but they must be atoned for by the blood of the man. That is the reason why men talk to you as they do from this stand; they understand the doctrine and throw out a few words about it. You have been taught that doctrine, but you do not understand it.
When talking about the doctrine, there is no mention of it being an LDS practice. His states that it is the principles on which it is based that are taught.
**In his preaching his used the conceptions in relation to the sin that he say around him, in the context of “If they only knew what they were doing to the eternal salvation they would ….” In this he is saying that they really don’t know what they are getting them selves into.
He states that although these principles have been taught, many still don’t not know their meaning.
So in the end it comes down to the question is there sin that is not covered by the sacrifice of our Lord.**
What then? shall we sin, because we are not under the law, but under grace? God forbid.
Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?*
Now where remission of these [is, there is] no more offering for sin.
For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
**These are the same things Brother Brigham was preaching on.
