Henry Warden (Dub) McClish, Jr. was born to Henry Warden (Red) McClish and Lena Maudie (Lewis) McClish at Itasca, Texas, on February 8, 1938.

At the age of 16, following his junior year of high school, Dub enrolled in Freed-Hardeman College (now F-HU). After receiving his A.A. degree there in 1957, he earned a B.A. degree in Bible from Abilene Christian College (now ACU).

Dub has preached fulltime for churches in Idaho, Texas, Alabama, Kentucky, and New Mexico. He preached for the Pearl Street church in Denton, Texas from 1980 to 1992 when he resigned to devote more time to writing, publishing and travelling.

In 1982, while preaching for the Pearl Street church, he began the Annual Denton Lectures which he directed until they were discontinued in 2002. He edited and published the books of these lectures that included textual studies on all of the New Testament, plus several books of the Old Testament.

Dub was founding editor of The Gospel Journal in 2000, which he edited until 2005. That same year he helped begin the Northpoint congregation in Denton, for which he preached until health problems forced his retirement in 2016. He then devoted most of his time to preparing material for his website, TheScriptureCache.com, an archive of some 500 articles and MSS on a wide variety of subjects from his 50+ years of writing.
