The Theological Awakening in 18th-Century Scotland

In the early 18th century, Scotland was dominated by the Church of Scotland, a national Presbyterian church structured with a state-approved theology and polity. It was during this period that John Glas emerged—a Reformed minister born in 1695 C.E., educated at the University of St. Andrews, and ordained in the Church of Scotland. His early ministry coincided with the post-Reformation struggle between biblical authority and ecclesiastical tradition.

Glas was deeply committed to the authority of Scripture, and it is this unwavering commitment that would place him at odds with the institutional church. A staunch adherent to the Historical-Grammatical method of interpretation, Glas believed that Scripture must determine church practice, not national or ecclesiastical decrees. His pivotal break with the establishment centered on one issue: the union of church and state.

Challenging the State Church: A Return to Apostolic Ecclesiology

In 1727 C.E., Glas published “The Testimony of the King of Martyrs,” where he argued that the national church model was incompatible with the pattern of the early church found in the New Testament. He asserted that the church of Jesus Christ should be a voluntary community of baptized believers, governed solely by Scripture, not by state authorities or synods. He wrote:

“The kingdom of Christ is not of this world, and its concerns are not to be managed by worldly politics or civil power.”

This was no minor disagreement. His assertion undermined the entire foundation of the Church of Scotland’s existence. Glas held that the primitive church—found in Acts and the Epistles—ought to be the model for ecclesiastical structure and worship. This included weekly observance of the Lord’s Supper, mutual exhortation among brethren, plural eldership, and the rejection of clerical hierarchy.

His opponents accused him of “anabaptism” and of sowing discord. In 1730 C.E., the Church of Scotland formally deposed him from the ministry. But Glas, following the examples of the apostolic church, continued to shepherd believers outside of the national structure. From this began the Glasite movement.

Ecclesiological Distinctives of the Glasites

What made the Glasite movement uniquely significant in Protestant history is its deliberate and consistent adherence to New Testament patterns, often paralleling what would later be known as Restorationism. The Glasites were committed to:

• Autonomous congregations governed by multiple elders, with no presiding bishop or centralized church government.

• Weekly observance of the Lord’s Supper, which they viewed not as a ritual but as a divinely commanded remembrance.

• A common meal as part of Sunday worship, echoing Acts 2:46.

• A commitment to church discipline, carried out according to Matthew 18:15–17.

• Congregational singing without instruments, to imitate the worship of the early church.

• Rejection of the tithe, which they viewed as a ceremonial law, favoring voluntary giving (2 Corinthians 9:7).

These principles aligned with the literal application of the New Testament, particularly Acts and the Pauline epistles. The Glasites were thus a model for later groups such as the Restoration Movement in 19th-century America, although they never reached wide influence due to their separation from both state and popular religion.

Theological Purity and Doctrinal Challenges

The Glasite movement was not without its doctrinal rigidity. Glas and his followers strictly emphasized the autonomy of each congregation to a point of isolationism. They also practiced foot washing, rejected marriage outside the faith, and held to communal sharing of material goods in the church.

However, these were derived not from mystical experiences or extrabiblical tradition, but from their literal reading of Scripture. While not all their practices are replicated among conservative evangelicals today, their commitment to sola Scriptura and ecclesiastical purity serves as a rebuke to churches influenced by culture and state interference.

Glas’s theology also contributed to a better-defined separation between civil society and the Kingdom of God. He anticipated later Evangelical doctrines on the church as a distinct, spiritual body not to be confused with any political order. This viewpoint was a crucial corrective to both Roman Catholic ecclesiocracy and state church alliances seen in Anglican and Lutheran contexts.

Legacy in Light of Biblical Authority

Though the Glasite churches dwindled in numbers, eventually merging or dying out by the 20th century, their theological DNA carried forward. Their influence can be seen in the Congregationalist, Baptist, and Restorationist traditions, each of which emphasizes:

• Local church autonomy

• Authority of Scripture alone

• Weekly Lord’s Supper

• Biblical eldership

• Rejection of creeds and councils as binding

More importantly, Glas’s insistence on using the New Testament church as the model remains a strong call to evangelicals today who are tempted to compromise with worldly models of church growth and governance. His approach to Scripture aligns with the conservative evangelical principle that the Bible interprets itself, and all doctrine must be rooted in exegesis, not tradition.

Revisiting John Glas from a 21st-Century Evangelical Lens

In today’s church landscape, John Glas stands as a reminder of the importance of ecclesiological faithfulness. His obscurity is not due to irrelevance but to the uncomfortable implications of his convictions. He challenges the prevailing consumer-oriented model of church. For conservative evangelicals, his life is an example of costly obedience to the text of Scripture.

Moreover, his theology was not speculative or abstract. It was grounded in the literal sense of the biblical text, carefully interpreted through the original languages and immediate context. This is evident in his application of Acts 2:42–47, Ephesians 4:11–16, and 1 Corinthians 11–14, where he derived his model of church life.

As evangelical churches increasingly face the threat of compromise with secular culture and the growing marginalization of biblical truth, John Glas’s witness provides a historically rooted alternative: faithful, Scripture-driven, congregational ecclesiology, untainted by tradition or state interference.

He never claimed new revelation, nor did he appeal to subjective spiritual experience. His authority rested solely in Scripture, interpreted rightly and applied rigorously. This makes him, not merely a figure of historical interest, but a relevant model for biblically faithful churches in every generation.
