At a testimony meeting of the general board of the Young Ladies Mutual Improvement Association invited guests Lillie T. Freeze and Maria Young Dougall speak in tongues and interpret. Sisters Freeze and Dougall are general board members in other auxiliaries and speak in tongues and interpret at such meetings until they die in 1937. By then glossolalia no longer occurs in LDS meetings, since all Mormons with this gift have died without successors. After 1930s LDS leaders redefine the "gift of tongues" to be xenoglossia, the ability to learn unfamiliar language (such as Japanese), rather than spontaneous speaking of "unknown tongues" which correspond to no recognized language.
