Our next interview of a theologian is with Dr. Robert Peterson, professor of systematic theology at Covenant Theological Seminary in St. Louis, Missouri. In addition to teaching on the seminary level, Dr. Peterson has extensive experience as a pastor, including church planting efforts, and has preached in Uganda and Peru on short-term mission trips. His pastoral experience is reflected in the practical emphases in his systematic theology classes.
Dr. Peterson is the author of Adopted by God: From Wayward Sinners to Cherished Children. In it he considers the beauty of God’s grace through the lens of the wonderful doctrine of adoption. His treatment of this great doctrine is accompanied by moving personal stories of father-child relationships. You can listen to him lecture in seminary on union with Christ and adoption here.
1. Dr. Peterson, why did you write this book about theological adoption?
I wrote Adopted By God because the Bible’s teaching on adoption was so neglected. In 1688, an important theology book by Francis Turretin was published in which he subordinated adoption to justification. This book became a standard theology text, whose example other writers of influential theology books followed, including Charles Hodge, Louis Berkhof, and Millard Erickson. These books are partially responsible for adoption’s neglect by teachers and preachers who studied them. Justification is vitally important, but adoption deserves more attention than it has received.
2. What do you cherish most about the doctrine of adoption?
I cherish the fact that it powerfully communicates the grace of God to believers, as powerfully as any biblical teaching. “See what kind of love the Father has given to us, that we should be called children of God; and so we are” (1 John 3:1). Adoption intimately communicates the Trinity’s love for each individual believer as well as for the people of God as a whole. “But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons. And because you are sons, God has sent the Spirit of his Son into our hearts, crying, ‘Abba! Father!’” (Galatians 4:4-6).
