How might Christian communities take up war-making and peacemaking as acts of discipleship?
Nigel Biggar thinks that Western Christians are willfully ignoring that soldiers and military action are essential to social peace and justice.
The just war tradition is meant to be more than a tidy checklist of criteria for evaluating a conflict. The tradition developed not as a theory to be bandied about, but as a rigorous ecclesial practice that arose out of the church’s day-to-day life and shapes that life. The tradition is a form of Christian discipleship, an expression of the character of Christian communities concerned daily with justice and with loving their near and distant neighbors.
