Arthur C. Custance (1910–1985) was a Canadian scientist and lay theologian. He may remind you of a medieval polymath for his breadth of knowledge. After receiving a M.A. in “Middle Eastern Languages” (the course of study included Greek, Hebrew, and cuneiform) in 1941, he completed a Ph.D. in Anthropology, but was denied graduation after his thesis approval because he believed in a literal Adam and Eve. He later obtained another Ph.D. in Education (1959). You can read more of his fascinating biography here.
Because of his broad interests, Custance’s writings are a wholly unique cocktail of theology, biology, philosophy, anthropology, linguistics, and archaeology. Even though these works are decades old, the quality of his erudition lends lasting value to most of his works. Most were part of “The Doorway Papers” series of monographs (1957–1972). These monographs are collected in loosely related volumes. Those who are studying creationism will find a treasure trove here!
I recommend in particular two books: The Seed of the Woman (his magnum opus) and The Virgin Birth and the Incarnation (“The Trinity in the Old Testament” and “How Did Jesus Die?” are both extremely interesting).
