Petcher, Donc

I apologize, but I cannot find any biographical information about an author named "Petcher, Donc" or "Donc Petcher" in academic databases or scholarly sources. The works you've listed - "Science and Grace" and "God's Reign in the Natural Sciences" - suggest engagement with theology and science dialogue, but I cannot verify these titles or locate information about this author's contributions to philosophy of religion or theology. Without reliable biographical data, academic affiliations, or verified publications, I cannot provide an accurate scholarly biography. If this is perhaps an alternate spelling or there are additional identifying details about this author, that information would be helpful in locating proper biographical sources.
