[George Q. Cannon]
Bro. Erastus Snow and Bro. L. John Nuttall arrived from the South this morning. We were glad to have them here as it was intended to hold a meeting of the First Presidency and Twelve to lay before them the subject of the organization of the School of the Prophets. At 3 p.m. we met – ... The minutes of the previous meeting respecting the School of the Prophets were read and approved. There was much speaking, principally by Bro. Erastus Snow, about the order of the washing of the feet in the Kirtland Temple and the washing of feet for the School of the Prophets, it being evident from the remarks that these were distinct ordinances, or in other words that the washing of feet as an introductory ordinance to the School of the Prophets was practiced long before endowments were given, when the feet of the Elders were washed in the Temple.
