LDSMS publishes tribute to Samuel W. Richards; lists the announcement of the Adam-God doctrine as one of the events marking his time as mission president.
"Memorial Presented to Elder Samuel Whitney Richards," The Latter-day Saints' Millennial Star 16, no. 40 (October 7, 1854): 629
It has fallen to your lot to preside over the British Saints at a time and under circumstances unparalleled in the history of the work in this country. The introduction of the Law of Celestial Marriage, which in its operations, will revolutionize all our political, religious, and domestic arrangements; and the announcement of the position which Adam, our great progenitor, occupies among the Gods; have marked your Presidency as a special epoch in the history of the British Mission.
