From the Life of Joseph Smith
The introductory part of the lesson provides a nice synopsis of the original formation of the society: Sarah Granger Kimball and Margaret A. Cook decided to create a charity society. But this took a very different direction when the plan came before Joseph Smith. His response, according to a very late reminiscence, was: “This is not what you want. Tell the sisters their offering is accepted of the Lord, and he has something better for them than a written Constitution.” (p. 449) I don’t know how accurately Sister Kimball remembered the occasion, but the words are significant: Joseph seems indeed to have wanted to replace the “written Constitution” with a living constitution.
