If Joseph thought of Freemasonry as degenerate priesthood, he did nothing to suppress his rival. Once the Nauvoo lodge was organized, Mormons joined in large numbers. Eleven of the Twelve Apostles became Freemasons. By October 1842, the 253 members of the Nauvoo lodge outnumbered the 227 Masons in all the other Illinois lodges combined. The Mormons organized four additional lodges over the next year. In June, less than seven weeks after bestowing the endowment on the first group of brethren, Joseph celebrated "St. Johns day," in honor of John the Baptist, a Masonic favorite, by riding in procession to a public celebration attended by thousands. In April 1844, the Saints dedicated the Nauvoo Masonic Hall, the finest completed building in the city.
