It is widely recognized that in some of his letters, Paul develops a Christology based on a comparison between Adam and Christ, and that this Christology has antecedents in Jewish interpretation of Genesis 1-4. Felipe Legarreta gives careful attention to patterns of exegesis in Second-Temple Judaism and identifies, for the first time, a number of motifs by which Jews drew ethical implications from the story of Adam and his expulsion from Eden. He then demonstrates that throughout the "Christological" passages in Romans and 1 Corinthians, Paul is taking part in a wider Jewish exegetical and ethical discussion regarding life in the new creation.
