The Core Apostolic Church

The Core Apostolic Church (Kerygmatic movement)

The Core Apostolic Church is the model for the Kerygmatic movement. By “Core Apostolic,” we mean the church as it existed within the living memory of Christ’s apostles, as witnessed by the documents closest to that community: Luke-Acts and the letters of Paul. These writings preserve the apostolic kerygma in its earliest recoverable form, before centuries of theological development reshaped the Christian message into something the original heralds would not have recognized.

Those within the movement identify as Kerygmatic Christians or Core Apostolics. Both terms express the same conviction: that the apostolic kerygma, as preserved in the Core New Testament, is the standard of our faith. “Kerygmatic” points to the proclamation itself. “Core Apostolic” points to the community that first proclaimed it. The identity is one and the same.

The Core Apostolic Church was not defined by a creed. It was defined by a proclamation: that the God of Israel had fulfilled His promises through Jesus the Messiah; that this Jesus, who was crucified, God raised from the dead and made both Lord and Christ (Acts 2:36); and that forgiveness of sins is offered to all who repent and are baptized in his name (Acts 2:38). This kerygma is what Peter declared at Pentecost, what Paul carried across the Roman world, and what both testified to be one and the same message: “Whether then it was I or they, so we preach and so you believed” (1 Cor 15:11).

What Made the Core Apostolic Church Distinctive

A kerygma, not a creed. The earliest church proclaimed events, not doctrines. God had acted in Jesus. Jesus had been raised. The Spirit had been poured out. The call was to repent and believe. The elaborate theological systems that would later define “orthodoxy” were centuries away.

An exaltation Christology. The apostolic proclamation identifies Jesus as a man attested by God with mighty works, whom God exalted as Lord and Christ through the resurrection (Acts 2:22-36). Jesus’s authority is not self-derived; it is given to him by God. This is the Christology of the kerygma, and it is the Christology we confess.

A unified message across diverse contexts. Paul preached to Gentiles in Asia Minor and Greece. Peter preached to Jews in Jerusalem. Yet the kerygmatic structure of their proclamation was the same: scriptural fulfillment, the death and resurrection of Jesus, his exaltation by God, the gift of the Spirit, and a call to respond. The Core Apostolic Church held together not through institutional uniformity but through a shared proclamation.

The apostles’ doctrine as practice. The response to the kerygma was concrete: repentance, baptism in the name of Jesus Christ, and receiving the gift of the Holy Spirit (Acts 2:38). These are not later liturgical additions; they are the apostles’ own prescribed response to their own proclamation. The Core Apostolic Church practiced what it preached.

Why “Core Apostolic” Matters Today

Every generation of Christians faces the same question: how do we distinguish the original apostolic faith from the accumulated traditions that surround it? The Core Apostolic Church provides the answer. It is not a denomination or an institution but a standard: the faith as it was actually proclaimed and practiced by the apostles themselves, preserved in the documents closest to their ministry. The Kerygmatic movement exists to recover that standard and to build communities of faith upon it.

The Core New Testament: The Root of Apostolic Christianity

The Core Apostolic Church is accessible to us because its witness was preserved in writing. The Kerygmatic movement identifies Luke-Acts and the writings of Paul as the definitive witness to true Apostolic Christianity. Together, these writings form the Core New Testament: the earliest and most historically grounded record of the apostolic kerygma (see https://CoreBible.app).

Luke is the most reliable Gospel. A careful historian who reviewed everything from the beginning (Luke 1:1-4), Luke produced a two-volume account of the Gospel narrative and the spread of the apostolic message. Luke-Acts provides continuity between the life and ministry of Christ and the proclamation of his apostles, preserving the kerygma as it was actually preached in synagogues and marketplaces across the Roman world.

Paul’s letters are the earliest Christian documents in existence, written within a few decades of Christ’s ministry. They preserve the kerygma he received from the Jerusalem apostles within a few years of the resurrection (1 Cor 15:3). Paul explicitly identifies his message as the same proclamation delivered by the Jerusalem apostles: “Whether then it was I or they, so we preach and so you believed” (1 Cor 15:11).

These writings preserve the original apostolic proclamation. The kerygma of Acts and the kerygma of Paul converge on a single message: that God fulfilled His promises through the death and resurrection of Jesus, whom He made both Lord and Christ (Acts 2:36), and that forgiveness of sins is offered to all who repent (Acts 2:38).

Many may regard additional books as Scripture, but the Core New Testament represents the shared foundation that all Christians can recognize as authoritative witness to the apostolic faith. By grounding our faith in these writings, we aim to realign belief and practice with the genuine apostolic witness, emphasizing the core simplicity of the faith as the apostles themselves proclaimed it. It is the scriptural basis from which the Kerygmatic movement takes its bearings.

Early Corruptions to the Faith

The traditional church has deviated far from the kerygma of early Apostolic Christianity. Within the first few centuries, the original proclamation was subjected to a series of corruptions that progressively reshaped Christian belief and practice. Understanding these corruptions is essential for any serious attempt at restoration.

Doctrinal Corruption. Over the centuries, Christian teachings were distorted, expanded, and overlaid with philosophical categories foreign to the apostolic proclamation. The kerygma announced that God made Jesus both Lord and Christ (Acts 2:36); later theology recast this as an ontological claim about a co-equal, co-eternal second person of a triune Godhead. The doctrine of the Trinity represents the most consequential of these doctrinal corruptions, transforming the apostolic proclamation of one God and one Lord into a metaphysical system the original heralds would not have recognized (see OrthodoxCorruption.com).

Textual Corruption. The New Testament manuscripts themselves bear the marks of theological interference. Foundational texts were subjected to layers of modification and expansion by later copyists, including what Bart Ehrman has documented as “orthodox corruption”: deliberate alterations to the text in favor of theological positions that developed after the apostolic period. The kerygma we seek to recover must therefore be read through critically established texts, not through manuscripts shaped by the very corruptions we aim to identify (see AICNT.org).

Illegitimate Canon. The traditional New Testament canon as received contains numerous books whose reliability, authorship, and authority remain contested. The traditional grouping of four Gospels treats them as equally authoritative, but the gospel narratives vary significantly in historical reliability, with several containing embellished or contradictory accounts. Some epistles attributed to apostles are later works written under false attribution. Not all books of the traditional canon were held at the same level of authority in the early church, and the process by which the canon was finalized reflected the theological interests of the proto-orthodox party, not a neutral assessment of apostolic origin (see NTcanon.com). The Core New Testament provides a more defensible foundation.

Fabricated Texts and Revisionist History. The dominant Roman and Eastern Orthodox churches suppressed dissenting views and shaped a revisionist historical narrative favorable to their authority. This included the introduction of forged documents, such as certain Ignatian writings, to manufacture a false continuity of doctrine from the apostolic period to later institutional orthodoxy. Recovering the apostolic kerygma requires distinguishing the genuine apostolic witness from later fabrications designed to legitimize post-apostolic developments.

Alteration of Christian Ordinances. The proto-orthodox church substantially altered the ordinances prescribed by the apostles, departing from the practices the kerygma itself established. Water baptism was changed from baptism in the name of Jesus (Acts 2:38; 8:16; 10:48; 19:5) to a tripartite formula based on Matthew 28:19, a text whose authenticity and interpretation remain disputed. The Lord’s Supper was transformed from a meal of remembrance, as Jesus instituted it (“Do this in remembrance of me,” Luke 22:19), into a sacramental act of consuming the literal body and blood of Christ, a development with no basis in the apostolic proclamation.

Committed to Bringing Reform to the Body of Christ

The Kerygmatic movement exists to recover what was lost: the original apostolic proclamation, free from later additions and philosophical overlays. This work of recovery requires both proclamation and reform.

We proclaim the apostolic kerygma. Our primary commitment is positive: to announce the same message the apostles announced, grounded in the Core New Testament and centered on the death, resurrection, and exaltation of Jesus as Lord and Christ. Everything else we do serves this proclamation.

We embrace textual criticism. Arriving at the most reliable and defensible scriptural foundation requires honest engagement with the manuscript tradition. We do not treat the received text as settled; we pursue the earliest recoverable text, recognizing that later copyists introduced corruptions that distort the apostolic witness (see corebible.app).

We challenge the received canon. The traditional New Testament canon has been treated as settled dogma, but its formation was a historical process shaped by theological interests. We actively identify issues with less reliable and later Gospel narratives in favor of the most primitive witness exemplified in Luke, and we reject fundamentalist assumptions about the canon that discourage critical inquiry (see NTcanon.com).

We expose distortions wherever they are found. Whether perpetuated by traditionalist institutions or contemporary Christian voices, false narratives about textual transmission, canonical development, and key theological concepts must be corrected. We encourage the Christian community to scrutinize long-held assumptions, recognizing that centuries of prevailing orthodoxy have embedded significant errors into mainstream tradition.

Above all, we seek to promote a genuine Christian faith motivated by love, guided by truth, and under God’s controlling influence. Reform without love is mere polemic. The kerygma the apostles proclaimed was not an argument to be won but an announcement to be received, and our work of restoration must embody the same spirit.
