This past July the annual conference of the American Scientific Affiliation (ASA), an organization of Christians in the sciences, offered a high-powered speaker lineup on the human brain and mind: Justin Barrett, director of the psychological science program at Fuller Theological Seminary; Audrey Bowden, assistant professor of electrical engineering at Stanford University; Edward Davis, historian of science at Messiah College; Douglas Lauffenburger, biological engineering professor at M.I.T.; William Newsome, director of Stanford’s Neurosciences Institute; and Los Alamos National Laboratory physicist Roger Wiens.

The equally intriguing 2017 conference, July 28-31 at Colorado School of Mines, will focus on environmental science and -- yes –- “climate change.” And on Oct. 11 the organization will be marking the 75th anniversary of its founding with a banquet at Wheaton College in Illinois. The current issue of the ASA quarterly, Perspectives on Science and Christian Faith (check here), is devoted to the group’s history, and Colorado State University molecular biologist Terry Gray has posted a series of historical articles.

Full membership in ASA is restricted to persons with bachelor’s degrees or beyond in the sciences who affirm the Apostles’ and Nicene Creeds and belief in “the divine inspiration, trustworthiness and authority of the Bible in matters of faith and conduct.” Most are evangelical-type Protestants.

Though members’ interests range from chaos theory to entomology to the morality of fracking, the most heated debates usually swirl around Darwin, evolution, creation, the Book of Genesis, origin of the universe and of earthly species and, therefore, what it means to be human.
