The issue of speaking in tongues has come up in a few threads I have participated in, but these were to some degree off-subject, so I thought it would be good to start a thread on the subject.
It has been asserted that all Christians should speak in tongues. The objection I have to this is that 1 Corinthians 12:28-31 clearly says that all do not speak in tongues.
1 Corinthians 12:28-31
In verse 29 the Greek word mh (me) is used. This word anticipates a negative answer. The NASB identified this fact and renders: "all do not...... are they?"
So, not all speak in tongues. The objection is raised: this is only referring to church meetings, for consider earlier in the chapter:
1 Corinthians 12:4-11

1 Corinthians 12:28-31
And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues.  29 Are all apostles? are all prophets? are all teachers? are all workers of miracles?  30 Have all the gifts of healing? do all speak with tongues? do all interpret? 31 But covet earnestly the best gifts: and yet shew I unto you a more excellent way. NKJV

So, not all speak in tongues. The objection is raised: this is only referring to church meetings, for consider earlier in the chapter:
1 Corinthians 12:4-11
There are diversities of gifts, but the same Spirit.  There are differences of ministries, but the same Lord.  And there are diversities of activities, but it is the same God who works all in all.  But the manifestation of the Spirit is given to each one for the profit of all:  for to one is given the word of wisdom through the Spirit, to another the word of knowledge through the same Spirit, 9 to another faith by the same Spirit, to another gifts of healings by the same Spirit, 10 to another the working of miracles, to another prophecy, to another discerning of spirits, to another different kinds of tongues, to another the interpretation of tongues. 11 But one and the same Spirit works all these things, distributing to each one individually as He wills.
The argument is made that this earlier section refers only to the church meetings (and thus the context for the whole chapter is the church meeting?). This position is not supported by the text.
Furthermore, you cannot take this supposition from verses 4-11 and apply it to to the later section in 1 Corinthians. "Are all apostles? are all prophets? are all teachers? are all workers of miracles?  30 Have all the gifts of healing?) does not apply only to the meetings. It is quite clear these roles are not restricted to meetings, but are ministries "tied" to individuals within the body of Christ.
A question that must be brooched is "What is speaking in tongues?" Quite clearly those demonstrated in Acts 2 were human languages. Is the claim that people who speak today speak other languages? In my experiences in a Pentecostal church before I became a member of Christ's church, was that these were not human languages, but just a selesction of sounds made by well-intentioned men and women.
