E. P. Sanders notes in his introduction to the next three testaments that they all three likely come from Greek-speaking Jewish author living in Egypt in the first or second century A.D. (OTP 1:869). They were, however, thoroughly taken over by Christians and became popular and influential books. Since there are no references to historical events in the books, they are difficult to date with precision. If the work is a translation of a Hebrew original, then it is possible to date the book as early as 200-165 B.C. (N. Turner, “The Testament of Abraham: A Study of the Original Language, Place of Origin, Authorship, and Relevance” (Unpublished PhD Dissertation, University of London, 1953) 242-48).
Sanders, however, believes the work was originally Greek, and can be dated no later than A.D. 117 because of the use of this work in the Apocalypse of Peter. Two recensions of the work appear in OTP, opinion is divided as to which is the older. The Judaism of the book is, as Sanders notes, “the lowest common denominator Judaism” (OTP 1:876).
This is a very interesting text to read and is one of the better written of the pseudepigraphal texts. It is very much an apocalypse since Abraham is taken on a heavenly tour with Michael as a guide. The final discussions with the personification of death clearly influence medieval thinking about Death (imagery, etc.). While the parallel to 1 Cor. 3 is possible, it seems better to find a reflection of a common thinking about “judgment” behind both Paul and T. Abraham. A more fruitful area of study is the “son of Adam” imagery in chapters 12-13. At the very least, this indicates a variety in the usage of the term “son of man” which may serve as a corrective to over-interpreting the gospel’s “son of man” sayings.
