w63 6/1 p. 344 Is Speaking in Tongues an Evidence of True Worship? ***
Those who seek these miraculous gifts that God no longer bestows upon his people lend themselves to such deception by Satan, and often the effects are embarrassing. Aside from the convulsive seizures and emotional shouting, D. A. Hayes in his book The Gift of Tongues described an incident similar to those reported by others. "At Los Angeles not long ago," he wrote, "a woman had the gift of tongues, and a reputable Chinaman who heard her said that she was speaking his dialect of Chinese. When he was asked to interpret what she said, he refused to do it, saying that the language was the vilest of the vile."
And from Pastor Russell's Sermons printed in 1917
On the contrary our experiences corroborate the declaration of St. Paul, that the operation of the holy Spirit of God in our hearts and minds has been favorable to the development of greater soundness of mind, by reason of our heed to the Word and its wisdom, which cometh from above. A WATCH TOWER reader in Los Angeles, Cal., writes that a neighbor woman got this so-called gift of tongues, and that a reputable Chinaman hearing her said that he understood her quite well--that she spoke his dialect of Chinese. Pressed for an interpretation he declined, saying that the utterance was the vilest of the vile.
