I don't think anyone is maligning those who have the true gift of tongues, only trying to let those who think that it is necessary to speak in tongues to be saved that it is not a necessity. 1 Corinthians 12:29-30 was mentioned and I would add 1 Corinthians 12:7-11 as proof that not everyone needs to speak in tongues. (7 Now to each one the manifestation of the Spirit is given for the common good.8 To one there is given through the Spirit a message of wisdom, to another a message of knowledge by means of the same Spirit, 9 to another faith by the same Spirit, to another gifts of healing by that one Spirit, 10 to another miraculous powers, to another prophecy, to another distinguishing between spirits, to another speaking in different kinds of tongues,[a] and to still another the interpretation of tongues.[b] 11 All these are the work of one and the same Spirit, and he distributes them to each one, just as he determines.) Also we are told that all believers with different gifts make up the body of Christ and not all can be a hand or a foot or tongue.
