Robert S. Rayburn (1950–) is an American preacher and pastor whose influential ministry within the Presbyterian Church in America (PCA) spanned over 40 years at Faith Presbyterian Church in Tacoma, Washington. Born on August 8, 1950, to Robert G. Rayburn, a key Presbyterian figure and founder of Covenant College and Seminary, he grew up immersed in ministry. After earning degrees from Covenant College, Covenant Theological Seminary, and a doctorate in New Testament from the University of Aberdeen, Rayburn began his pastorate at Faith Presbyterian on April 29, 1978, retiring in 2019. His expository preaching, rooted in covenant theology, produced thousands of sermons emphasizing biblical depth and practical faith, many archived online, while his leadership extended to roles like stated clerk of the Presbytery of the Pacific Northwest. Known as "the modern patriarch of covenant succession thinking," Rayburn’s 1996 essay on covenant children and nurture stirred debate in the PCA, complemented by his advocacy for paedocommunion in a minority report, though he adhered to denominational standards. Beyond preaching, he taught Latin at Covenant High School, supported global missionaries, and mentored future ministers, drawing inspiration from William Still’s long-term pastorate model. Married to Florence, he raised five children—Nathaniel, Joanna, Charlotte, Robert, and Sophia—in a home of theological richness, continuing to shape evangelical thought post-retirement through writings and reflections from Tacoma, leaving a legacy of intellectual and pastoral impact in the Reformed tradition.
