Wisdom from R. C. Sproul:
You can watch the full 1 hour and 15 minute discussion here, with Michael Horton, Stephen Meyer, R.C. Sproul Jr., and Del Tackett joining R.C. Sproul to answer questions about the Christian mind, science, old and new earth, and more.
For those interested in these questions, especially from a Reformed perspective, I would recommend reading the PCA Study Committee Report on Creation (2000), where a number of PCA elders from various persuasions on these issues studied and debated these issues in order to produce this report. It is worth reading simply for the definitions, and also for the way in which they seek to describe the strengths of, and objections to, the various orthodox positions.
Here is a flavor regarding how they are able to agree on the essentials despite significant differences:
We have found a profound unity among ourselves on the issues of vital importance to our Reformed testimony. We believe that the Scriptures, and hence Genesis 1-3, are the inerrant word of God. We affirm that Genesis 1-3 is a coherent account from the hand of Moses. We believe that history, not myth, is the proper category for describing these chapters; and furthermore that their history is true. In these chapters we find the record of God’s creation of the heavens and the earth ex nihilo; of the special creation of Adam and Eve as actual human beings, the parents of all humanity (hence they are not the products of evolution from lower forms of life). We further find the account of an historical fall, that brought all humanity into an estate of sin and misery, and of God’s sure promise of a Redeemer. Because the Bible is the word of the Creator and Governor of all there is, it is right for us to find it speaking authoritatively to matters studied by historical and scientific research. We also believe that acceptance of, say, non-geocentric astronomy is consistent with full submission to Biblical authority. We recognize that a naturalistic worldview and true Christian faith are impossible to reconcile, and gladly take our stand with Biblical supernaturalism.
The Committee has been unable to come to unanimity over the nature and duration of the creation days. Nevertheless, our goal has been to enhance the unity, integrity, faithfulness and proclamation of the Church. Therefore we are presenting a unanimous report with the understanding that the members hold to different exegetical viewpoints. As to the rest we are at one. It is our hope and prayer that the Church at large can join us in a principled, Biblical recognition of both the unity and diversity we have regarding this doctrine, and that all are seeking properly to understand biblical revelation. It is our earnest desire not to see our beloved church divide over this issue.
