C. E. McLain (1909-1990) 

Clifford E. “Mac” McLain was born in Blanchard, OK. He received a Bachelor of Theology degree from Atlanta Bible Institute and later his Doctor of Divinity from Trinity Bible Seminary in Atlanta. He was an associate of Dr. E.F. Webber, David Webber and Noah Hutchings.  

Dr. McLain founded Grace Institute of the Bible in Oklahoma City, and co-founded with Ben McCammon the Northside Bible Church in 1966. He was also host of the radio program, “What’s the Question?”  

Author of several books, McLain’s principal emphasis was on the calling of Ephesians 3:9: “To make all see what is the fellowship of the mystery.” Consequently, his works focused on the Apostle Paul’s epistles written after Acts 28:28 – the “Mystery” letters.
