Craig Evans has published another study online discussing the issue of Jesus' literacy. See: Jewish Scripture and the Literacy of Jesus - C. A. Evans and W. H. Brackney (eds.), From Biblical Criticism to Biblical Faith (Mercer University Press, 2007) 41-54. Skimming through it, it's a helpful response to the work of P. F. Craffert and P. J. J. Botha, “Why Jesus Could Walk on the Sea but He Could Not Read and Write,” Neot 39 (2005): 5-35. Botha argue for the illiteracy of Jesus in the fourth part of his paper, under the heading “Was Jesus Literate?” (pp. 21-32). Evans response, is to that section of the paper. As usual, Evans doesn't waste time and his familiarity with the material and the context in which Jesus was raised, lived and what the determining factors are, remain almost unmatched. The article assumes a knowledge of Greek, so either brush up or learn it, or just skip over. Another excellent offering from the mind of one of the greatest NT scholars alive.
