I’ve thought a lot about that address, and the comments i made during my semi-liveblog of that conference session still hold true, i think—basically, i think his message was rather muddled, and that he wasn’t successful at explaining whatever it is he wanted to say. This may be why i’ve heard and read his address used by Mormons to support claims that the leadership of the church wants its members to have as many children as physically possible (and perhaps not even stop there), and also that the leadership is cool with its members having however few children they want.
Consider the following lines (not next to each other, as it appears here) from the address:
When to have a child and how many children to have are private decisions to be made between a husband and wife and the Lord. These are sacred decisions—decisions that should be made with sincere prayer and acted on with great faith.
Many voices in the world today marginalize the importance of having children or suggest delaying or limiting children in a family…[Quotes from others went here, including a statement that “a biblical perspective on motherhood” requires having children]…As the world increasingly asks, “Are these all yours?” we thank you for creating within the Church a sanctuary for families, where we honor and help mothers with children.
(That last one was followed by stories of folks having children despite, e.g., still being in school—and this is all presented as a Good Thing.)
Sorry, but this just seems a bit of trying to have one’s rhetorical cake and eating it, too—everybody gets to make a private decision, but in the context that decision is always going to be to have lots of kids starting pretty much right away.
