C. John Collins, Did Adam and Eve Really Exist? Who They Were and Why You Should Care. The book is about 200 pages, soft cover, published in 2011 by Crossway.
Very informative book that delves into the Near Eastern background around the time of Moses and also around the time of the Apostles, quoting Josephus and others. He also quotes the Apocrypha that clearly states Adam was a real person. His conclusion is in line with what the Church has basically always held: if Adam and Eve were not really historical persons, why would we think Christ and the apostles were such? Paul basis his argument of Christ’s righteousness being applied to us on the fact of Adam’s real fall into sin, and also basis his argument for the resurrection on Adam’s real fall: “By man came death, by Man came also the resurrection of the dead” (1 Cor. 15:21). Because Eve was deceived and not Adam, Paul does not allow a woman to exercise authority over a man (1 Tim. 2), etc.
Moreover, Jesus based His argument for marriage on what many today deny: “Have you not read that He who made them at the beginning ‘made them male and female’”(Matt. 19:4; see also Mark 10:6). The genealogy of Christ goes back to Adam (Luke 3:38); the genealogy in Chronicles begins with Adam (1 Chron. 1:1); and Israel transgressed her covenant like Adam did (Hosea 6:7 ESV) and so on.
For an easy to read book that covers every conceivable passage regarding Adam in the Bible, this is it. If you need to do any research on Adam and Eve as historic persons, look no further.
The Church has never understood Adam and Eve as metaphors to help us understand the Bible, but as real persons, as the Bible clearly presents. It is usually modern distaste for the Bible that leads liberal scholars to deny the obvious. I decided decades ago that I would not be embarrassed by what God said in His written word. AMEN.
