Despite being a theologically conservative Baptist, Wonderly accepted the scientific evidence that the Earth was much older than young-earth creationists believe it to be. In explaining his views on evolution and the age of the Earth, he wrote, "Christians need to reject evolutionism, but when they reject true scientific discoveries they bring disgrace upon the Bible and Christianity." He supported reconciling the old age of the Earth with the teachings of the Bible by means of day-age creationism. When administrators at Grace College learned about Wonderly's unfavorable views of young-earth creationism and flood geology, they agreed to hire him only on the condition that he not interfere with the College's commitment to advancing young-earth creationism. Wonderly agreed, but after some of his students found out about his views, the College's president banned Wonderly from further discussing his views at all, prompting Wonderly to resign. Prominent young-earth creationist Henry Morris defended Grace's handling of Wonderly's anti-creationist views, arguing that these views were already receiving a fair hearing throughout society.
