I have created a PBB resource of J. Gresham Machen’s book The Literature and History of New Testament Times. You can download it by clicking on the attachment link below.
This book, originally published in 1915, may have been used as a Sunday School curriculum. It was published by the Presbyterian Board of Publication and Sabbath School Work. There are 52 chapters, one for each week of the year. The book also references a “Student’s Guide” but I haven’t been able to find this.
