Glossolalists could, apart from those practicing glossolalia, also mean all those Christians who believe that the Pentecostal/charismatic glossolalia practiced today is the "speaking in tongues" described in the New Testament. They believe that it is a miraculous charism or spiritual gift. Glossolalists claim that these tongues can be both real, unlearned languages (i.e., xenoglossia)[42][43] as well as a "language of the spirit", a "heavenly language", or perhaps the language of angels.[44] Cessationists believe that all the miraculous gifts of the Holy Spirit ceased to occur early in Christian history, and therefore that the speaking in tongues as practiced by Charismatic Christians is the learned utterance of non-linguistic syllables.
