Theodore Epp

Theodore H. Epp (January 27, 1907–October 13, 1985) was an American Christian preacher, radio evangelist, and author, best known as the founding director of Back to the Bible, a globally influential radio ministry. Born in Oraibi, Arizona, to Russian Mennonite immigrant missionaries working with the Hopi Indians, Epp grew up in a faith-filled environment. Converted at age 20 in 1927 under Norman B. Harrison’s teaching in Flagstaff, Arizona, he pursued theological education at Oklahoma Bible Academy, Hesston College in Kansas, and the Bible Institute of Los Angeles (now Biola University), earning a Th.M. from Southwestern Baptist Theological Seminary in Fort Worth, Texas, in 1932. Epp’s preaching career began as a pastor in Goltry, Oklahoma, at Zoar Mennonite Church (1932–1936), where he married Matilda Schmidt in 1930, raising six children—Gerald (who died young), Eleanor, Herbert, Bernice, Marilyn, and Virginia. In 1936, he joined T. Myron Webb’s radio ministry, and on May 1, 1939, launched Back to the Bible in Lincoln, Nebraska, with just $65, trusting God for provision. The program grew from a 15-minute local broadcast to a daily 30-minute show on over 800 stations worldwide in eight languages by his 1985 retirement, featuring his expository preaching and music from the Back to the Bible choir and quartet. He authored nearly 70 books, including David: A Man After the Heart of God and Practical Studies in Revelation, emphasizing practical faith and biblical literacy.

Sermon Summary
Theodore Epp emphasizes four essential marks of a Christian as outlined in Galatians. Firstly, a true Christian has Christ living within them, signifying a personal relationship with Him. Secondly, the presence of the Holy Spirit is crucial, as He transforms believers and shapes their character. Thirdly, Christians share in the experience of the cross, which is fundamental to overcoming personal struggles. Lastly, a Christian embodies a divine life that transcends mere external regulations, reflecting the transformative power of God.
The Marks of a Christian
Galatians 2:1-10 Four marks of a Christian are set forth in the Book of Galatians. First, a Christian is one who has the living Christ living in him. "I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me" (Gal. 2:20). Second, a Christian is one who has the Holy Spirit within him, for in Galatians 4:6 we "And because ye are sons [if we are born again into His family], God sent forth the Spirit of his Son into your hearts." He is the One who really begets us, or creates us anew, and makes us believers. He also creates in us the new character from which Christian conduct comes. Christian conduct does not make a Christian, but a true Christian, one who is born of the Holy Spirit, will have Christian conduct as well. In the third place, a Christian is one who has shared the cross experience with Christ as the basic solution of his personal problems. We all have come under this experience of the cross although we may not all have understood it. The key text on this subject is "I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me" (2:20). When Christ died, I died with Him, and when He arose, I arose with Him. In the fourth place, the Christian is one who is possessed of a life that is so divine, so ideal, that it cannot be pushed into a mold of external regulations. We have a new life, a life from God, which is Christ Himself. "Examine yourselves, whether ye be in the faith; prove your own selves" (2 Cor. 13:5).
