J. Gresham Machen
J. Gresham Machen (1881–1937) was one of the most courageous defenders of biblical Christianity in the modern era—a brilliant New Testament scholar and a steadfast leader who refused to compromise when the foundations of the faith were under assault. In an age when many churches drifted toward liberal theology, Machen raised a clear, unwavering voice calling believers back to Scripture, clarity, and conviction.
Machen was born in Baltimore, Maryland, into an educated and cultured home. His mother, a devout Christian, shaped his early faith, while his father, a prominent lawyer, modeled careful thinking and integrity. After studying at Johns Hopkins and Princeton Theological Seminary, Machen traveled to Germany to study under leading scholars—experiences that exposed him to theological liberalism firsthand.
Those encounters became pivotal. Machen admired academic rigor, but he saw clearly that liberal theology—despite its sophistication—emptied Christianity of its supernatural heart. He returned to Princeton more convinced than ever that true faith rested not on human ideas but on the historic gospel of Christ: His incarnation, His atoning death, and His bodily resurrection.
As a professor of New Testament at Princeton, Machen was beloved for his sharp mind, dry wit, and deep devotion to his students. He did not retreat from modern scholarship; he engaged it boldly. His landmark book The Origin of Paul’s Religion dismantled the claim that Christianity borrowed from pagan ideas, showing instead that it sprang from the real-life person and work of Jesus.
But his most famous work was Christianity and Liberalism (1923), a book that sent shockwaves through the church. With precision and courage, Machen argued that theological liberalism was not simply a lighter version of Christianity—it was a different religion altogether. Christianity was built on divine revelation; liberalism was built on human opinion. Christianity proclaimed salvation through Christ; liberalism preached self-improvement. The two could not coexist.
The battle for Princeton intensified throughout the 1920s. When the seminary shifted steadily toward liberal control, Machen and other conservatives founded Westminster Theological Seminary in 1929—a school committed to the authority of Scripture and the Reformed faith. Machen became its first and most influential professor, shaping a generation of pastors and scholars.
Yet Machen’s stand did not end in the classroom. When the mission board of the Presbyterian Church endorsed liberal theology, he helped form the Independent Board for Presbyterian Foreign Missions. For that act of conscience, the denomination suspended him from the ministry. Machen accepted the cost without bitterness, believing faithfulness to Christ outweighed institutional approval.
In 1936, he helped establish the Orthodox Presbyterian Church, a new denomination grounded in historic, confessional Christianity.
Machen’s final days were marked by physical exhaustion from winter travel to support small congregations. He fell ill in North Dakota and died on January 1, 1937. His last telegram, sent to a friend, read: “I’m so thankful for the active obedience of Christ. No hope without it.”
Those words summed up his life. Machen devoted himself to defending the real, supernatural gospel—a gospel rooted not in feelings or trends, but in the finished work of Christ.
