How has the church's understanding of salvation grown and shifted over time? What are common misunderstandings that Catholics and Protestants have about salvation? How has this impacted the church? And what is the future of justification as that connects to ecumenical efforts? Eminent church historian Alister McGrath (University of Oxford) has been research and writing about the history of salvation in the church for over 40 years. In light of his freshly revised monograph, Iustitia Dei, McGrath leads us on a tour of the history of the Christian doctrine. Co-hosted by Matthew W. Bates.
