Why do some people say Pentecostal beliefs aren't Bible based?

As a pentecostal myself, I can say that NO one actually follows every thing in the bible, but we try not to commit the sins of man. And the way we no what sins not to commit is by the use of the bible, it is a reference for Pentecostals. We don't say that were perfect but we try to follow the rules of the bible.

Some of the problem comes from some of the specifics of various Pentecostal statements of faith. Pentecostals see the support in the Bible, whereas others do not.

The following subsections illustrate some particulars where Pentecostals and non-Pentecostal Christians differ:

Tongues, Salvation, and the Baptism of the Holy Spirit

Some Pentecostal groups believe that speaking in tongues is the evidence of the indwelling of the Holy Spirit and/or the baptism of the Holy Spirit. Others make the connection that one cannot be saved without one or both of those, and thus the person who has never spoken in tongues is not saved.

Acts chapter 2 provides an example where speaking in tongues is evidence at the initial baptism of the Holy Spirit. Other portions of Acts, however, do not mention this. Pentecostals assume that the tongues were there, non-Pentecostals often assume they were not there.

Tongues and Unknown Languages

Pentecostals tend to believe in a "heavenly" language or a "prayer language" that is distinct from being able to speak an existing language without having first studied it. 1 Corinthians 14 is often used as support for this prayer language, known technically as glossolalia. Non-Pentecostals see the phrase, "If I speak with the tongues of men or of angels" as being exaggeration used to make the point that it doesn't matter from what source the tongues come, without love they are worthless.

As a side note, the ability to speak extant languages is known as xenoglossy. Double-click on these words to find a definition from Answers.com, or use the Web Links to the right to see the Wikipedia articles on both of these.

Each Sin "Un-Saves" You

Some Pentecostals believe that, since sin separates man from God, that each instance of a sin removes your salvation, and that you must be saved again in order to get to Heaven. Others believe that God's grace will continue, although returning to a life of habitual sin (i.e. bringing a particular sin back into one's life without remorse) risks one's entry into Heaven. Still others believe that one can never lose one's salvation, even by walking back into a life of sin.

Demonstrative Worship

The Pentecostal style of worship tends to be very loud and emotional. Some non-Pentecostals, and even some who bear similarities to Pentecostals in other ways, refute this, citing passages in 1 Corinthians dealing with orderly conduct.
