The gifts of prophecy, tongues, interpretation of tongues, and words of wisdom and knowledge are called the vocal gifts. Pentecostals look to 1 Corinthians 14 for instructions on the proper use of the spiritual gifts, especially the vocal ones. Pentecostals believe that prophecy is the vocal gift of preference, a view derived from 1 Corinthians 14. Some teach that the gift of tongues is equal to the gift of prophecy when tongues are interpreted. Prophetic and glossolalic utterances are not to replace the preaching of the Word of God nor to be considered as equal to or superseding the written Word of God, which is the final authority for determining teaching and doctrine.
