I purchased a copy of Michael W. Holmes' The Apostolic Fathers: Greek Texts and English Translations, 3rd ed. (Grand Rapids: Baker Academic, 2007) at AAR/SBL last week. It is a crisp looking volume. The solid green cover allows it to sit nicely next to my NA 28, BHS, etc. Holmes has included a helpful Index of Ancient Sources in the back, so I decided to use it to see how often John the Baptist is mentioned in the corpus of the Apostolic Fathers. The results?
I may be missing something, but using Holmes' index the only mention of John, and the only time a passage related to John is obviously quoted/echoed by the Apostolic Fathers, is when Ignatius says the following in 1:1 of his Letter to the Smyrnaeans (Holmes, 249):
This echoes Jesus' words to John in Matthew 3:15 (NRSV):
I don't know what to make of this quite yet, but it is curious. Why was John either (1) hushed or (2) forgotten by those who would come to be known as the Apostolic Fathers? Why is John absent from most of their extent writings while appearing in the Gospel of the Ebionites, the Gospel of the Nazarenes, and the Infancy Gospel of James?
