Fred Flack (July 11, 1907 – November 19, 2012) was an English preacher and missionary whose ministry spanned over eight decades, serving the gospel in England, India, the Philippines, and beyond with a focus on indigenous church planting. Born in Southampton, England, alongside his twin brother John—the UK’s oldest known twins by 2007—to a Christian family, he grew up shaped by faith and a call to serve. Educated at the Missionary Training Colony (MTC) in London in the early 1930s, he honed his preaching skills through open-air treks before sailing to India in 1937 with Raymond Golsworthy to join Bakht Singh’s movement. Flack’s preaching career began with MTC’s rigorous evangelistic outings, walking up to 400 miles to share Christ, and flourished in India, where he spent 40 years preaching among local believers, emphasizing simplicity and dependence on God. His sermons, like those on SermonIndex.net, reflect a gentle yet resolute call to faith, delivered globally until nearly age 100. Author of books such as According to the Pattern (1943, later The Tent of His Splendour) and Bringing Many Sons to Glory (1944), he ministered tirelessly, even in retirement from Sidmouth, Devon. Married to Margaret “Meg” Haskell in 1949, whom he met in India, they had no children but shared a life of service until her death in 1999. Flack died at age 105 in a Southampton nursing home.
