The idea of Jesus initiating a second humanity and new creation by His incarnation, death, and resurrection is an important but often undervalued emphasis in the New Testament and in patristic theology. In A Second Adam, Cody Cook presents this doctrine, called Recapitulation, as a biblical, ancient, and ecumenical model of the atonement which is simultaneously more balanced than the more popular models while also getting us to their most important insights. Christus Victor, satisfaction, penal substitution, liberation, and theosis models of salvation are shown to be imbalanced when taken as central, but can all be held in harmony when starting from Recapitulation. Recapitulation is also shown to have great promise for future ecumenical dialogue and apologetics concerns.
