Robert Adam Holliday Lusk (March 8, 1781 – December 14, 1845) was a Reformed Presbyterian or Covenanter minister of the strictest sort, in a century which, according to Presbyterian historian Robert E. Thompson, was marked by increasing relaxation into less stringent manifestations of doctrine and practice amongst all branches of Presbyterianism.Thompson, Robert Ellis. A History of the Presbyterian Churches in the United States. New York: The Christian Literature Co., 1895. His career crossed paths with many prominent ministers and he was involved in numerous ecclesiastical courts at pivotal moments in the history of the Reformed Presbyterian Church. Amongst Reformed Presbyterians, he was an "Old Light," and amongst "Old Lights," he would lay claim to be an "Original Covenanter." He was descended from a long line of Scotch-Irish, and the Lusks had fled from Scotland to Ireland, escaping religious persecution;Stiles, Henry R.

Early life and education

Robert Lusk was born near the city of Derry, Ireland, to William Lusk and Elizabeth Holliday, on March 8, 1781. He was the youngest of five children. He emigrated to America, in 1792, with his parents, shortly before the Irish Rebellion of 1798. They settled in Cumberland County, Pennsylvania.

In 1804, he began to attend the Academy of Greensburgh, Pennsylvania, which prepared him for his course of study. After this, he entered Jefferson College, located in Canonsburg, Pennsylvania. The choice seemed quite natural for someone reared in a dissenting Presbyterian tradition. The College boasted an impressive number of graduates occupying ministerial connections in dissenting bodies, including Reformed Presbyterians, James R. Willson and James Milligan.Smith, Joseph.

Advanced theological training and licensure to the ministry

Attending the Theological Seminary of the Reformed Presbyterian Church

By all accounts, he was endowed with superior intellect and displayed a thirst for knowledge. He was noted for his proficiency in both sciences and medicine. But it was in his theological studies that he displayed his endowments most signally. He studied theology in the Philadelphia Seminary (a Reformed Presbyterian school long since defunct) under the tutelage of Samuel B. Wylie. The Constitution of the Theological Seminary had restricted entrants to those "who had previously graduated some college or university," with allowances for rare exceptions.Extracts from the Minutes of the Proceedings of the Judicatories of the Reformed Presbyterian Church in the United States. New York: Abraham Paul, 1816. Lusk needed no exception; his course of study commenced immediately following his graduation from Jefferson College.

Prof. Samuel B. Wylie reports to Synod, in 1812, that Lusk had already attended his studies for two years. Furthermore, he had completed the "proper literature of the institution, and was prepared to enter the third class; agreeably to the constitution of the seminary." The said Constitution had provided that the first class would consist in Biblical Literature, in order to qualify the student to understand "the sacred text." The second class would consist in Pulpit Eloquence, in order to qualify the student to expound "in a persuasive manner the oracles of God." The third class would consist in Systematic and Polemic Theology. This was designed to establish the student in the "analogy of faith" pursuant to the Testimony of the Reformed Presbyterian Church and a studious eye to the Confessions of the Reformed Churches. It was a course of study designed to encompass four years. The first "class" occupied the first year; the second "class" occupied the second year; the third "class" occupied the third and fourth years.Copeland, Robert M. Spare No Exertions: 175 Years of the Reformed Presbyterian Theological Seminary. Pittsburgh: Published by the Seminary, 1986.

Ministerial trials and licensing to preach

In 1814, Lusk, along with three other classmates, Jonathan Gill, Samuel Robinson and Robert Wallace, was requested by Synod to deliver a discourse, "in relation to systematic and polemical theology." Additionally, each received a theological examination with respect to "the analogy of faith, pursuing the plan laid down in the testimony of the Church." Prior to rendering its final verdict, the four were removed from the chamber, in order that observations might be freely made and judgments formed. When doubts were raised concerning Wallace, Wylie stated that "Wallace must be a proficient in Greek, as he had studied under the great Young." Additionally, it was stated, "That Lusk had more science than all in the class; but he was too proud—he must be humbled."

The Synod's examining board was satisfied with the results and declared that Lusk had honourably passed. Whereby, he was duly and fully certified by the Synod. At which point, Synod referred him to the Middle Presbytery for trial, "with a view to licensure, and if found duly qualified," to be licensed to preach the gospel as a minister of the Reformed Presbyterian Church. This was on May 7. Two days later, he was licensed by the Middle Presbytery, on May 9, 1814.Steele, David. "Memoir of the Rev. Robert Lusk." Contending Witness 3.5 (March 1846) ed. David Steele. Xenia, Ohio: J.H. Purdy. On May 12, Middle Presbytery reported their action licensing Lusk to preach and delivered him back up to Synod for disposal. Synod instructed Lusk to move expeditiously to the Northern Presbytery.

In 1815, while still a licentiate, Lusk first visited the societies associated with the Elk (named for the Elk River), later re-christened Hephzibah, Reformed Presbyterian congregation, near Fayetteville, Tennessee, because they were without the benefit of a regular ministry.

On September 26, 1815, the Board of Trustees of Jefferson College met, at that meeting Dr. McMillan and his colleagues conferred several A.M. degrees. Among the honored was "Robert Lusk, of Cumberland county." Lusk's post-graduate studies were recognized by his alma mater.

Ordination and first ministerial charge in the Reformed Presbyterian Church

He was ordained to the office of the ministry and installed pastor of the Conococheague congregation, Chambersburgh, Franklin County, Pennsylvania, on August 12, 1816. Conococheague had been a hive of Covenanter activity predating the erecting of the Reformed Presbytery, in 1798. That same year, he was married to Miss Margaret Thompson, of Conococheague, Pennsylvania, with whom he had two daughters, Hannah Anne (1819–1869) and Mary Jane (ca. 1820–1901). Margaret was the daughter of John Thomson, who, along with John Renfrew, John Steele and John Scouller, was one of the four ruling elders of the congregation at this time.

Shortly after Lusk's installation, a log meeting house was erected in Greenwood, Pennsylvania.

Moderator of Synod, 1817

Evidently, his esteem amongst his ministerial colleagues increased. He served as Moderator of the Synod, which met in Coldenham, New York, in 1817. Although it was common for moderators, at that time, to sit for portraits, Lusk is not represented in the commonality; there are no known images of this moderator, except those conjured up by words. At this meeting of Synod, Lusk was part of a committee, which also included Alexander McLeod and fellow Jefferson College alumnus James Milligan. In 1807, the Reformed Presbytery had proposed a plan to "exhibit their principles to the world," which, they explained, would embrace three parts. The first part was to be Historical and exhibit the Church in her visible society in covenant with God, at various points in history, particularly that situation which holds forth the Reformed Presbyterian Church as a distinct part of the Catholic Church. The second part was Declaratory, exhibiting "the truths which they embrace as a Church, and the errors which they reject." The third part was to be Argumentative and was to consist in full and critical investigations of the "various ecclesiastical systems which are known in the United States."Reformation Principles Exhibited, by the Reformed Presbyterian Church in the United States of America. New York: Hopkins and Seymour, 1807. The committee was appointed to inquire into the "propriety of redeeming" the decade old pledge of Synod to complete the argumentative defence "for truth and against errors and immoral practices." This was to form the third part of the testimony of the Church. The committee sat, deliberated, and bore fruit. In 1818, Synod began making assignments for drafting articles for this part of the Testimony. Although he was absent from Synod that year,Extracts from the Minutes of the Synod of the Reformed Presbyterian Church, Session VII-1818. Lusk was given the assignment to write critically on the "ecclesiastical system" of Methodism.

Sometime, in 1818, the Roxbury society was added to Shippensburg. Additionally, his time was divided ministering to Covenanter societies, in Newville, Walnut Bottom, Shippensburg, Green Township, Lurgan, and Waynesboro, small Pennsylvania towns scattered from some distance from his regular charge (mainly along what is today, Pennsylvania Route 997). However, he remained the stated, regular pastor of the Conococheague congregation until he tendered his resignation.

Increasing participation in ecclesiastical governance

Activities on behalf of Synod

On December 15, 1818, he, along with Revs. Alexander McLeod and William Gibson, participated in the regular organization of the Baltimore, Maryland, Reformed Presbyterian congregation and the installation of John Gibson as its pastor. On August 10, 1819, the Synod of the Reformed Presbyterian Church met in Conococheague, John Cannon (who would again, in 1833, preside over the split into "Old Light" and "New Light" factions) presided, as moderator. At the beginning of this Synod, Lusk arose to read some of the minutes of the committee of Middle Presbytery relating to John Gibson's ordination and installation at Baltimore, after which Gibson was requested to be seated in Synod.Extracts from the Minutes of the Synod of the Reformed Presbyterian Church, Session VIII-1819. At the close of Synod, he was requested to preach the opening sermon, on the substitutionary nature of Christ's sufferings, at the next meeting of Synod, to be held in 1821 at Samuel B. Wylie's church in Philadelphia.

On December 19, 1819, Lusk was once again in Baltimore, Maryland, where he and Alexander McLeod would help administer the sacrament of the Lord's supper for the first time in that congregation.
