Nigel Biggar, Regius Professor of Moral and Pastoral Theology at the University of Oxford, joins the GodPod team this week. How might Christians approach debates about ethical issues, such as euthanasia and abortion, in the public square? And what about the place of forgiveness and reconciliation between communities in troubled areas like Northern Ireland?

Should Christians be vegetarians for ethical reasons? The regular team debates this, and the question of how Old Testament laws fit into New Testament ethics.
