It's nice to see the LDS Church recognized that the tradition of marriage is an ever-changing one:
For much of Western history, family “interest”—economic, political, and
social considerations—dominated the choice of spouse. Parents had the
power to arrange marriages or forestall unions of which they
disapproved. By the late 1700s, romance and personal choice began to
rival these traditional motives and practices. By Joseph Smith’s time, many couples insisted on marrying for love, as
he and Emma did when they eloped against her parents’ wishes. (See here.)
It's a small admission, but it's a hell of a lot better than their usual homophobic bullshit about "traditional marriage" going back to Adam and Eve. Here the Church admits that women have long been considered property of a man (like in D&C 132:62) and an important trade commodity (think of the tradition of asking for a father's permission and his agreement to "give away the bride"). Kudos.
Let's do what we can to avoid reinstating that tradition where it has fallen out of use.
