John Reuther (birth year unavailable–) is an American preacher and pastor whose ministry has centered on Reformed Baptist theology since the 1980s. Born in New Jersey, he was raised in a Roman Catholic family and converted to evangelical Christianity at age 19 while studying music at Montclair State College. Introduced to the gospel through evangelical friends, he attended church services that solidified his faith in Christ’s finished work, leading to his assurance of salvation. He earned a BA from Northeastern Bible College in 1977 and an MDiv from Biblical Theological Seminary (now Missio Seminary) in 1984. In June 1977, he married Wendy, and they have five children—two daughters and three sons—all married, with eleven grandchildren as of recent records. Reuther’s preaching career began in earnest when he started regular pulpit ministry at Covenant Baptist Church in Lumberton, New Jersey, in July 1985, a church planting work supported by his home church in West Chester, Pennsylvania, and Trinity Baptist Church of Montville, New Jersey. Ordained on December 8, 1985, during the church’s official constitution, he has pastored this congregation for over 39 years as of 2025, emphasizing expository preaching and biblical doctrine. His ministry extends beyond the pulpit as a lecturer for Reformed Baptist Seminary on the Holy Spirit and through missionary teaching in Japan (1975) and other regions. Known for his scholarly approach and love of woodworking and model trains, Reuther remains active, leaving a legacy of steadfast service within the Reformed Baptist community, though his influence is primarily regional rather than globally prominent.
