George Henry Gerberding called Weidner's Studies in the Book his most original contribution to theology. These volumes, covering the entirety of the New Testament and parts of the Old, are based on lectures given by Weidner to students at the Moody Bible Institute in Chicago, IL. In them, he gives outlines of Scriptural books, detailing their primary emphasis and theological themes. He provides details about the authorship and dating of each book.
This volume covers the book of Genesis. In it, Weidner develops his biblical theology as drawn from figures like Karl Keil, Franz Delitzsch, and Gustav Oehler, as he exposits major themes from the first book of the Bible. He criticizes the historical critical school throughout the text, and argues that Genesis was written by divine inspiration, and that its themes find their end in Christ.
