A marker takes the colour of the side it landed on — blue toward the left pole,
orange toward the right. The shape says which tradition; the colour never does.
The rails draw the classical Pentecostal bodies, the Assemblies of God, the Church of God and the Church of God in Christ, against Southern Baptists of the traditional, non-Calvinist kind. The convention's Calvinist stream stands elsewhere on grace and is drawn separately, and the Oneness Pentecostals, who baptise in Jesus' name and hold to the oneness of God rather than the Trinity, are a different story again.
What they share
Scripture alone, with nothing over it. Neither has a bishop, a synod or a creed a congregation must sign. Each church calls its own pastor, owns its own building and answers for itself, and both land in the same band at the far end of the authority rail.
Grace that reaches everyone. Both stand firmly on the free-response side: God's call goes out to all, and each person has to answer it. That is why both keep the invitation, the moment at the end of the service when anyone ready to trust Christ is asked to walk to the front.
The Table as a memorial. In both, the bread and the cup remember and proclaim Christ's death rather than carrying grace themselves, and baptism is the full immersion of someone old enough to ask for it. Neither baptises babies.
Worship with no book. No set readings, no church calendar to follow, no prayers written down centuries ago. The service is whatever the congregation builds out of singing, prayer, an open Bible and a sermon.
The same map of the future. Both lean dispensational, expecting the church to be caught up before a time of tribulation and holding that God's promises to national Israel will be kept. Pentecostal statements say so outright; among Baptists it runs through the preaching and the study Bibles rather than the confession.
Where they differ
Both sides below are stated the way people who hold them would state them. Landing in
the same band is not agreeing, and landing in different ones is not a verdict.
Pentecostals hold that what happens in Acts is still on offer. The Assemblies of God teaches that baptism in the Holy Spirit is a distinct experience after conversion, marked by the initial physical sign of speaking in tongues, which means praying in a language the speaker has never learned. It is the normal Christian inheritance, not a prize for the unusually holy. Healing belongs to the same package: prayer for the sick happens at the front, out loud, with hands laid on, because these churches hold that healing is provided for in Christ's atonement and is meant for now.
Baptist
cessationist-leaning
Baptists lean the other way with no document to point at. No Baptist confession says the gifts have ended. There is a long settled practice of not seeking them and a conviction that Scripture is enough without them, which is why the rail stops short of the pole. Baptists pray for the sick and believe God heals, and they will tell you the Holy Spirit is at work all week through preaching, providence and answered prayer rather than through gifted individuals. Tongues in a Sunday service would stop the room, and in most congregations it is simply not part of what happens.
In plain wordsOne church expects the Holy Spirit to do something you can hear on a Sunday morning; the other expects Him to work quietly, through the sermon and through answered prayer.
Beyond the compass
The Compass measures six things, not everything. These differences are real and
sit outside all six.
Can a Christian fall away?
The Compass asks whether grace can be refused, and both sides say it can. It does not ask what happens afterwards, and there the two part. The traditional Southern Baptist position is eternal security: once someone truly believes, God keeps them, which is where once saved, always saved comes from. Most Pentecostal bodies hold that a person who has genuinely believed can later walk away, so assurance is real but is not a sealed verdict. It changes what a pastor says to someone frightened that they have lost it.
Who may preach
The six axes do not measure church order, and this is a difference a visitor could notice on the first morning. The Assemblies of God ordains women as ministers, and they pastor churches. The Baptist Faith and Message holds that while both men and women are gifted for service in the church, the office of pastor is limited to men. Pentecostals are not uniform here either: the Church of God in Christ does not ordain women as pastors, though its women's department is large and long established.
How they came to differ
Both traditions were built by American revivals, a lifetime apart. Baptists came up through the frontier camp meetings, where the gospel was offered to whoever happened to be under the tent, and the Southern Baptist Convention formed in 1845. Pentecostalism arrived in 1906 in a run-down mission at 312 Azusa Street in Los Angeles, under William J. Seymour, the son of former slaves, with Black and white worshippers in one room in a segregated city.
The new movement did not fall out of the sky. It took its account of grace from the Wesleyan holiness movement, which is why it still sounds like Wesley on that question, and many of its first preachers came out of existing free churches, Baptists among them. The Church of God began at Barney Creek, Tennessee, in 1886 as a holiness church; the Church of God in Christ was a holiness body before Charles Harrison Mason reorganised it as Pentecostal in 1907; and the Assemblies of God formed at Hot Springs, Arkansas, in April 1914.
What those preachers carried with them is why the rails sit so close together. Congregational government, immersion, the memorial Supper, the invitation at the end of the service and Scripture alone all came along unchanged. One thing was added, and that one thing is the whole argument.
Walking in
A Baptist service has a shape even without a book: songs, a welcome, prayer, a long sermon straight out of one passage, then the invitation, sung while anyone who wants to come forward does. Communion arrives monthly or quarterly. A Pentecostal service starts in the same room and goes further. The sung worship runs longer, someone may speak in tongues aloud and someone else give the interpretation, and the last stretch belongs to people at the front being prayed over by name, hands on their shoulders, for healing and for the Holy Spirit.
Did you know?
The largest Black Pentecostal body in America was built by a former Baptist preacher. Charles Harrison Mason parted from the Baptists over holiness teaching, went to the Azusa Street revival in 1907, received the Spirit there, and came home to make the Church of God in Christ a Pentecostal church.
