I had classified four types of Christians, regarding Tongues.
1. Those who speak in tongues and belong to a denomination that actively practices it. This would include Assembly of God (who are Trinitarian) as well as United Pentecostal, who are non-Trinitarian (Oneness Pentecostals) and other pentecostals.
2. Those who have received the gift of Tongues, but remained in whatever denomination they were in; denominations not necessarily known for Tongues -- they are charismatics, interspersed through many denominations. I am in this group.
No - not necessarily. With me, the gift came about a year subsequent to salvation. With some, it may be years after salvation.
3. Those who do not speak in Tongues themselves, but have no hard and fast belief against it; iow, they are not "Cessationists", they simply never received the gift.
4. The Cessationists; not only do they not speak in Tongues themselves, they hold a doctrine that the gift has "ceased" -- along with Prophecy and Word of Knowledge. These three alone are what Paul prophesied would "cease" when "that which is perfect" should come. Perfect can also mean complete or mature. The Cessationists hold that the completion of the New Testament marks this famous "perfect"; non-cessationists (Continuationists) hold that THE PERFECT will not be seen til Christ returns.
By far the majority of Christians today are in classification #3. I cannot speculate on the numbers of classifications 1, 2 and 4. Those in 4 are adamant and vocal that tongues, prophecy, and Word of Knowledge are not operating today.
