He comes to this conclusion:

The Ecumenical Call discusses the justifiable use of armed force, and concludes “there are extreme circumstances where, as the last resort and the lesser evil, the lawful use of armed force may become necessary.” This is a difficult conclusion for many Christians, and yet it would reflect the broad views of Canadian Anglicans as expressed in these official statements through the years.

A clear and consistent pattern of belief is evident in the documents surveyed here. Violence and war are incompatible with Christ’s teaching. Christian responsibility is to build up communities of peace founded upon justice for all people and for the earth itself. Peacemaking and reconciliation are at the heart of the Christian gospel.

I would have thought that the violent death of God’s son offered as a propitiation for the sins of the world is at the “heart of the Christian gospel”, rather than the polysemous vagueness of “peacemaking and reconciliation”. But, then, I’m not an Anglican bishop.
