Not marriage. Not really. A question about marriage is the impetus for the revelation, and information about it is given at a few points, but that information is always incidental, and given to illustrate points about the revelation’s larger theme.
Consider that section 132 is the last revelation Joseph Smith received that’s included in the Doctrine and Covenants. What might be the most important message of that book overall for the Saints in this dispensation? It’s one that is indeed extremely important and relevant for us this very day.
In 66 verses, the word “marriage” is only used two times. Other marriage-related terms occur not much more often: “marry” and “sealed” occur six times each, “concubines” and “wives,” four times each. The most commonly used marriage-related terms are “wife” and “adultery,” which occur ten times each; and “adultery” is always mentioned in material that’s meant to ensure that that sin is not committed.
Contrast that with the frequency of these other significant terms:
- Commanded, commandment, priesthood – 7 times each
- According, appointed, received—9 times each
- Exaltation, receive—11 times each
- Abide—12 times
- Power, word—13 times each
- Covenant—15 times
- Servant—16 times
And perhaps the most important term of all, as suggested by frequency of use:
- Law—32 times
