Pentecostal churches place particular emphasis on the activity of the Holy Spirit in Christian life, but Pentecostalism is not one denomination with one complete set of rules. Congregations belong to different church bodies, and important differences can sit behind a shared religious label.
A useful introduction therefore brings history and specific teachings together. For congregation research, it also asks which organization a church belongs to, how that relationship is documented, and whether the available contact information is current. Those questions produce a clearer picture than treating a worship style or a directory category as a complete identity.
Revival history and distinct church bodies
The Assemblies of God (USA) identifies the Azusa Street revival of 1906 to 1909 as a major focus of the emerging Pentecostal movement. Its historical overview describes the Los Angeles ministry of William J. Seymour, an African American Holiness preacher, and the revival's influence beyond its original congregation. It separately dates the organization of the Assemblies of God to 1914.
The Church of God in Christ's history offers another organizational perspective. It emphasizes holiness and traces Charles Harrison Mason's ministry through Baptist and Holiness settings. The account describes his 1907 journey to Los Angeles and encounter with Seymour's preaching as a turning point.
These accounts show connections between a wider revival movement and particular denominational histories. They should not be compressed into a claim that every Pentecostal church was founded at Azusa Street or joined the same organization afterward. A local congregation's founding date is another question again, requiring evidence about that community.
Spirit baptism in a specific statement of faith
The Assemblies of God's Statement of Fundamental Truths describes baptism in the Holy Spirit as distinct from and following the new birth. It connects that experience with empowerment for life and service and identifies speaking in tongues as its initial physical evidence. The statement also affirms Trinitarian belief in one God and three persons.
That is a precise account of the denomination's teaching. It is more informative than saying that Pentecostal worship is simply emotional or unusual. It also needs to remain attributed: a religious statement explains what a church teaches, while a claim about a particular person's experience is a different kind of evidence.
When writing a congregation profile, distinguish the published doctrine from what was observed at a service or reported in an interview. An individual testimony may be important to its speaker, but it cannot establish that every member has the same experience or that every Pentecostal body defines that experience in the same way.
Why Oneness and Trinitarian teaching should not be merged
The United Pentecostal Church International presents a different account in its overview of beliefs. Its Oneness teaching describes one God revealed as Father, through the Son in redemption, and as the Holy Spirit. It identifies Jesus Christ as God manifested in flesh.
The UPCI's account also connects obedience to the gospel with repentance, water baptism in Jesus Christ's name, and baptism in the Holy Spirit with speaking in tongues as the initial sign. These details should be read within the UPCI's own explanation rather than inserted into another denomination's statement.
The comparison demonstrates why a broad Pentecostal field does not settle questions about the Godhead, baptism, or salvation. Shared vocabulary does not erase doctrinal differences. A fair description names the source of each teaching and avoids presenting one group's understanding as the uncontested position of the whole movement.
Research the congregation behind the event
Imagine a community arts researcher documenting a church choir's appearance at a local festival. The event program gives a shortened church name and the festival venue, while the congregation's website provides its full name and affiliation. The festival is evidence of that appearance; it is not automatically evidence of the church's regular worship address.
Build the profile from those sources according to what each establishes. Record the choir's event separately from the congregation, confirm the church's location, and retain the wording of the source that identifies its organizational connection. If a denomination provides a directory, compare the entry with the local church's own published information.
Do not infer an affiliation from the music, the speaker's title, or a photograph of the service. Equally, do not infer that a church is independent merely because a directory omits a denomination. These may be useful leads for further checking, but they are not confirmations.
Keep current visitor information separate from historical notes. Someone planning to attend needs the right location and schedule, while someone studying a congregation's development may need former names and earlier venues. A date and a source for each detail allow both kinds of research to coexist without confusing their purposes.
What a dated directory can and cannot show
Oddity's U.S. Churches Database covers multiple denominations. Its listed version, 1.0.36, is dated August 22, 2015. The advertised 110,003 records describe the entire product, not a verified Pentecostal congregation count or a count of individual believers.
The listed fields include organization names, addresses, denomination labels, and some telephone and website information. Denomination is populated for 67,826 records. Those labels can help organize research, but they do not provide a complete account of a congregation's beliefs, current leadership, or relationship to other churches.
Use the older records to identify leads, then verify the facts needed for your project. Preserve the original vintage, record any newer confirmation, and keep unresolved matches visible. The strongest result connects each church to its own evidence while recognizing the diversity that a general Pentecostal category cannot express.
