Leonard Lewis Sankey (1936–) is an American preacher and missionary whose extensive ministry has significantly shaped the InterChurch Holiness Convention (IHC) and Evangelistic Faith Missions (EFM) over decades. Born on April 7, 1936, in Greenville, Pennsylvania, to William P. and Leona May Adams Sankey, he graduated from high school and attended God’s Bible School and College, earning a Bachelor’s in Theology in 1960. That same year, on September 17, he married Janet May Ferguson in Greenville, and they soon began their ministry together, initially as song evangelists before transitioning to preaching. The couple raised three children—Pamela Beth, Anita Lavonne, and Leonard Marc—and embarked on missionary service with EFM in 1962, serving in Guatemala for two terms and Honduras for one, totaling several years in Central America. Sankey’s preaching career expanded significantly upon returning to the U.S., where he served as pastor of Faith Mission Church in Bedford, Indiana, from 1979 to 2009, establishing Stone City Christian Academy during his tenure. He held various roles at EFM’s headquarters from 1975 to 1979, including deputation secretary, office manager of The Missionary Herald, and interim president. A key figure in the IHC, he assisted General Secretary Harold Schmul from 1955 and succeeded him in 1997, serving until 2016, when he was named General Secretary Emeritus. His ministry, spanning sixteen nations and thirty-six states, focused on holiness preaching and church planting, leaving a legacy as a stabilizing force in the holiness movement through his leadership and tireless proclamation of the gospel.
