Many other worship experiences in the Kirtland Temple prior to and after the dedication included references to people speaking and interpreting tongues. In describing the beliefs of the church in the Wentworth letter (1842), Joseph Smith identified a belief of the "gift of tongues" and "interpretation of tongues". The practice of glossolalia by the Latter-day Saints was widespread but after an initial burst of enthusiastic growth circa 1830–34, seems to have been somewhat more restrained than in many other contemporary religious movements.[36] Young, Smith, and numerous other early leaders frequently cautioned against the public exercise of glossolalia unless there was someone who could exercise the corresponding spiritual gift of interpretation of tongues, so that listeners could be edified by what had been said.
