Since the 19th century secular geologists have argued for an old earth. Unfortunately, this old-earth a priori has become an assumption of many professing evangelical geologists, as well as theologians. According to current “scientific thinking” the earth is 4.6 billion years old. In effect, this assumption is considered by many to to be the same as “general revelation.” As a result, the “general revelation” of an earth that is 4.6 billion years old has motivated many influential evangelicals to reinterpret the early chapters of Genesis. This recently surfaced in the May/June 2010 issue of Modern Reformation when eight PCA geologists wrote an article, “PCA Geologists on the Antiquity of the Earth,” that minimizes biblical revelation on the basis of a naturalistic worldview.
In response to this, Dr. John K. Reed wrote an outstanding article refuting the eight old-earth PCA geologists. Since Dr. Reed holds a PhD in geology and is committed to the primacy of Scripture, I highly recommend that you read his article “A Response to the Old-Earth Advocacy of Campbell et al., PCA Geologists on the Antiquity of the Earth.”
