In the past few decades there has been a growing controversy in society and in the Church over evolution and the age of the earth. Some Christians accept the idea of billions of years, as taught by the scientific establishment, while others contend that Scripture requires that we believe that creation is only a few thousand years old. Systematic theology texts are influential in this debate as they are used in the training of future pastors, missionaries, and seminary and Christian college professors and are also read by many lay people, thus affecting the Church's witness. After briefly explaining the evidence in defense of the young-earth creationist view and why this subject is important, three deservedly respected theology textbooks will be examined regarding their teachings on the age of the earth. It will be argued that in spite of their many helpful remarks, these scholars have not adequately explained the biblical truth on this subject nor have they persuasively defended their old-earth positions and provided convincing rebuttals to the young-earth view. On this subject then, I conclude, these systematic theology texts are not helping but rather hindering the Church in her witness in our evolutionized world. (This is a slightly revised version of a paper the author presented at the annual meeting of the Evangelical Theological Society in November 2006. Two of the authors of the critiqued texts [Grudem and Lewis] read the paper shortly thereafter but to date have given no specific responses to this critique of their views.)
