speaking in tongues don't be too quick to an opnion

Glossolalia or speaking in tongues, according to linguists, is the fluid vocalizing of speech-like syllables that lack any readily comprehended meaning, in some cases as part of religious practice in which it is believed to be a divine language unknown to the speaker The first occurrence of speaking in tongues occurred on the day of Pentecost

St Paul says the one who speaks in tongues speaks not to man but God about the mysteries of the Holy Spirit.
