Robert Bunger Thieme, Jr. was pastor of Berachah Church, a nondenominational Christian church in Houston, Texas, from 1950 to 2003. Affectionately called "the Colonel" by his congregation, he was a dispensationalist theologian who wrote over a hundred books and conducted over 10,000 sermons on various theological topics during his 55 years as a pastor.
Thieme however became a highly controversial figure within Evangelicalism, as some of his doctrinal teaching on pastoral authority, the atonement, the blood of Jesus and his moral teachings became the subject of controversy in the 20th century.
