I read part of this book for an assignment for internship.
Jonathan Leeman presents the view (mission is centered on salvation) I would agree with and would commend his article and responses.
Christopher Wright argues for our mission being the same as God's mission. This view is flawed by failing to see the central problem of the Bible as sin and alienation from God as well as by failing to see that we do not imitate God in every single way (dying on the cross, for example).
John Franke presents the pragmatic view which sees mission as changing in every context and culture. This view, honestly, can hardly be considered legitimate by any who take the Bible seriously.
Peter Leithart takes what could be considered a sacramental-ecumenical-political view. If that sounds confusing, join the club (haha). Stemming from his views on Federal Vision and Postmillennialism, he argues that the sacraments are central to the mission of the church in that they bring together the nations and are the root of social progress. His view is hard to nail down and untangle, but essentially fails by confusing justification by faith alone, obscures the exclusivity of the gospel, and misunderstands the relationship between the church and the state. However, he does well to highlight the importance of the sacraments (Jesus does highlight baptism in the Great Commission), though they must be explained differently.
