As Lord Wilmore is posting about ancient cosmology and temple themes in Alma 12, among other things, my mind goes back to a scripture we have discussed before
9 And now Alma began to expound these things unto him, saying: It is given unto many to the of God; nevertheless they are laid under a strict command that they shall not impart according to the portion of his word which he doth grant unto the children of men, according to the heed and diligence which they give unto him.
10 And therefore, he that will his heart, the same receiveth the portion of the word; and he that will harden his heart, to him is the greater portion of the word, until it is given unto him to know the mysteries of God until he know them in full.
11 And they that will harden their hearts, to them is given the lesser of the word until they concerning his mysteries; and then they are taken captive by the devil, and led by his will down to destruction. Now this is what is meant by the of . (Alma 12)
I want to focus on the word, mysteries, this time. It is found once in each of these three verses. Considering the temple themes in Alma 12-13, this quote from Hugh Nibley is interesting:
In a recent and rather sensational work, Morton Smith demonstrates at length that the word mystery, as used by the first Christians, usually refers to ordinances. He duly notes that Judaism itself was an ancient “mystery religion” in which the rites of circumcision and passover were “mysteries,” and that such early and orthodox Christian writers as Clement of Alexandria “think of Jesus as a ‘hierophant,’ a teacher of mysteries.” As Smith sums it up, “This was the mystery of the kingdom—the mystery rite by which the kingdom was entered,” i.e., the ordinances of initiation. (Hugh Nibley, “The Message of the Joseph Smith Papyri”, 515)
It should be added that Morton Smith's work is disputed and scholars disagree about the possible meaning of "mysteries" in relation to ordinances. But I don't think the point is that "mystery" always refers to an ordinance, but that there is a clear relation and one possible meaning depending on context. At least it makes sense to me that the sacred ordinances anciently were viewed as mysteries of God that were only available for and understood by the faithful. In Greek, mystery (musterion) comes from mueo, which is related to initiatory rites. Of course the Nephites did not speak Greek but this relation might go back to the ancient Israelites as the quote indicates. In this context it makes sense that Alma goes on to talk about ordinances later in his sermon.
8 Now they were after this manner—being called with a holy calling, and ordained with a holy ordinance, and taking upon them the high priesthood of the holy order, which calling, and ordinance, and high priesthood, is without beginning or end...
16 Now these were given after this , that thereby the people might look forward on the Son of God, it being a of his order, or it being his order, and this that they might look forward to him for a remission of their sins, that they might enter into the rest of the Lord. (Alma 13)A natural question to ask is then: If those who know the mysteries of God (like Alma) are strictly commanded to impart only a limited portion according to the heed and diligence of the recipient, why would Alma start lecturing the wicked Ammonihahites about these deeper temple themes? I think the answer is given in Matthew 13:
10 And the disciples came, and said unto him, Why speakest thou unto them in ?
11 He answered and said unto them, Because it is given unto you to know the of the kingdom of heaven, but to them it is not given.
12 whosoever hath, to him shall be , and he shall have more : but whosoever hath not, from him shall be taken away even that he hath.
13 Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.
14 And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall , and shall not understand; and seeing ye shall see, and shall not perceive:
15 For this people’s is waxed gross, and their ears are dull of hearing, and their they have ; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should them.
16 But blessed are your , for they see: and your ears, for they hear.
The Isaiah quote in verse 15 forms a chiastic pattern with heart, ears and eyes in that order before it is reversed. Even though Alma 12-13 can hardly be called a parable, it is a layered sermon. The plain language is for all to hear and the deeper covenant symbols, presumably only recognized by those among the listeners who were familiar with the temple theology, are reserved to those who had not hardened their hearts but instead opened their eyes and ears. King Benjamin talks about this
And these are the words which he and caused to be written, saying: My brethren, all ye that have assembled yourselves together, you that can hear my words which I shall speak unto you this day; for I have not commanded you to come up hither to with the words which I shall speak, but that you should unto me, and open your ears that ye may hear, and your that ye may understand, and your that the of God may be unfolded to your view. (Mosiah 2:9)
These words are spoken right after the description of the people gathering around the temple and as we know, the sermon ends with the people entering into a covenant and receiving a new name.
Nephi also talks about the mysteries of God. As he starts writing on the small plates, he is a middle-aged man reflecting back on his life. This is the very first verse of his account
I, Nephi, having been of , therefore I was somewhat in all the learning of my father; and having seen many in the course of my days, nevertheless, having been highly favored of the Lord in all my days; yea, having had a great knowledge of the goodness and the mysteries of God, therefore I make a of my proceedings in my days. (1 Nephi 1:1)
He even tells his readers how he first came to know the mysteries of God.
And it came to pass that I, Nephi, being exceedingly young, nevertheless being large in stature, and also having great desires to know of the of God, wherefore, I did cry unto the Lord; and behold he did me, and did my heart that I did all the words which had been spoken by my ; wherefore, I did not against him like unto my brothers. (1 Nephi 2:16)
In line with Alma's statement, Nephi had a soft heart and was therefore ready to learn about the mysteries of God ("he that will not harden his heart"). His great desires and crying unto the Lord triggered the process. Nephi later advises his readers to follow the same pattern.
18 For he is the yesterday, today, and forever; and the way is prepared for all men from the foundation of the world, if it so be that they repent and come unto him.
19 For he that diligently shall find; and the of God shall be unfolded unto them, by the power of the , as well in these times as in times of old, and as well in times of old as in times to come; wherefore, the of the Lord is one eternal round. (1 Nephi 10)
We must seek diligently to have the mysteries of God unfolded unto us. Nephi is talking from experience. Again, this is in line with Alma's statement that the portion of God's mysteries we receive is in accordance with our diligence.
To me, this is related to the "forbidden to write" series. Because of the underlying principles for obtaining knowledge about the mysteries of God, sometimes the prophet can only say this much and then needs to stop. Other times, he will talk with layers of meaning, where only the diligent and initiated with open eyes, ears and hearts can pick up the deeper layers.
