C. Wilfred Griggs is a modern archaeologist, Egyptologist, Coptologist and a scholar of early Christian and Latter-day Saint history (he is a Latter-day Saint). He contributed to the excavations at the Nag Hammadi site in Egypt for University of California (UC), Berkeley and at Seila, Fayum, Egypt for the Brigham Young University, Hawaii (BYU) and UC Berkeley. There, in Seila, he excavated a Christian cemetery, and wrote about his findings, Excavating a Christian cemetery near Selia, in the Fayoum region of Egypt (check here and here).[1]He also wrote an important book, Early Egyptian Christianity: From Its Origins to 451 C.E.[2]
His book, Early Egyptian Christianity, is definitely worth reading, though one cannot agree with him on every subject. There are certainly very important points which I hope to come back to in a different article.
