Thomas Campbell, an Argyle Scot by lineage, was born in North Ireland in 1763, took a full classical course in the University of Glasgow, and after that the full course in the theological seminary of the Anti-Burgher section of the Seceder branch of the Scottish Presbyterian Church. After preaching and teaching for several years, he became the settled pastor of a church at Ahorey, in County Armaugh, thirty miles south of Belfast, where he remained from 1798 until 1807. Meanwhile he had married the daughter of a French Huguenot family, and his son Alexander had been born in 1788. While ministering to the Ahorey church, he also conducted a private academy at the neighboring town of Rich Hill. Throughout his life, Thomas Campbell devoted more of his time to teaching than to preaching. The Seceder Presbyterians had split from the established Church of Scotland in 1733 in protest against the arrangement by which the right of appointing ministers had been taken from the parishes and given to lay “patrons,” or landlords, for whom the right to appoint the parson went with their ownership of land. No question of doctrine was involved in this secession. The Seceders were, if anything, stricter Calvinists than the Church of Scotland. Later, the Seceders divided into Burghers and Anti-Burghers, and each of these into New Lights and Old Lights, on fine points concerning the relations of the church to the state. These divisions were carried from Scotland to Ireland, though the issues were irrelevant to conditions there. Thomas Campbell was an Old Light, Anti-Burgher Seceder Presbyterian. But he early outgrew any interest in these divisive issues and sought ways of promoting unity at least among the Seceders. Aside from the odious examples of disunion before his eyes, two other influences drew Thomas Campbell toward a wider fellowship. One was the Independent (Congregational) church at Rich Hill, a church of the Scotch Independent type, strongly affected by the ideas of Glas and Sandeman and the Haldane brothers. Here he met the celebrated English evangelist, Rowland Hill, who preached an ardent gospel that took little account of sectarian boundaries, and the eccentric John Walker of Dublin, who left the Episcopal Church and resigned a fellowship in Trinity College to lead an independent movement. Campbell was already familiar with the writings of Glas and Sandeman and with the work of the Haldanes. None of these was explicitly an advocate of union; but they all played down the doctrines and creeds which create divisions and the ecclesiastical institutions which perpetuate them; and all played up a warm evangelical faith voluntarily accepted and a return to the simple practices of the New Testament church.
