Justin Welby has been the Archbishop of Canterbury since 2013. Before he began training for ministry in 1989, Archbishop Justin worked in the oil industry for 11 years.
His new book, The Power of Reconciliation encourages peacebuilding at all levels, turning the abstract idea of reconciliation into something that can be done throughout life.
Krishnan joined the Archbishop at Lambeth Palace to talk about what reconciliation is, and how we can use it to approach wars, culture wars and personal conflicts as well as what the role of church is in a time of war.
