Wenham had the distinction of being a conservativetheologian, a defender of biblical inerrancy, and one who held to the position of "conditional immortality" – or the belief that the human soul is not by default eternal in nature; this belief goes hand in hand with the notion that sinners, once cast into hell, are at some point burned up and essentially no longer exist. In his book Facing Hell, An Autobiography 1913–1996, Wenham writes, "I believe that endless torment is a hideous and unscriptural doctrine which has been a terrible burden on the mind of the church for many centuries and a terrible blot on her presentation of the Gospel. I should indeed be happy, if before I die, I could help in sweeping it away." Facing Hell was published shortly after his death and is largely autobiographical, though also containing a paper Wenham published in regard to the doctrines of conditional immortality and the limited temporal nature of hell.
Academic work
Among New Testament Greek scholars, Wenham's work The Elements of New Testament Greek is well regarded, and was the successor to Nunn's introductory Koine Greek textbook. In 1992 John Wenham published Redating Matthew, Mark and Luke which discusses the dating of these gospels and the relationship of the gospels to one another. Wenham accepted the church father evidence of authorship, and inferred a very early date for each of the synoptic gospels. Wenham's work is well regarded by those who supported the Augustinian hypothesis which is the traditional view of gospel authorship. Scholars consider the two strongest defenders of the Augustinian Hypothesis in the twentieth century to be John Wenham and B.C. Butler. Wenham's work which gained him recognition among Bible scholars and lay persons was his work Easter Enigma which offered Bible exegesis that argued for the harmony of the gospel accounts. As a result of these two works Wenham is frequently cited in regard to these issues in the discipline of Christian apologetics. In his work Redating Matthew, Mark and Luke Wenham wrote regarding the book of Matthew the following: "The fathers are almost unanimous in asserting that Matthew the tax-collector was the author, writing first, for Hebrews in the Hebrew language: Papias, Irenaeus, Pantaenus, Origen, Eusebius, Epiphanius of Salamis, Cyril of Jerusalem and others write in this vein. The Medieval Hebrew gospel of Matthew in Even Bohan could be a corrupted version of the original. Though unrivaled, the tradition has been discounted on various grounds, particularly on the alleged unreliability of Papias, from whom some would derive the whole tradition.". Wenham also argued for the Gospel of Mark being the second gospel written which he claims is consistent both with internal evidence and with the testimony of the church fathers.
