You stupid UPC people, Glossolalia HAS NO BIBLICAL BASIS, XENOGLOSSY DOES. "there appeared unto them cloven tongues like as of fire,.." divided unto all of the individuals in the "upper room". They were said to speak in "other tongues as the spirit gave them utterance". Acts records that everyone in a nearby crowd was able to understand what the Apostles were saying at Pentecost, whereas glossolalia as usually practiced today is unintelligible to everybody including the speaker!!!
