the archbishop of canterbury has used his christmas sermon to preach a message of support to volunteers helping refugees. the most revjustin welby was speaking at canterbury catherdral this morning. the christmas story shows us how we must treat those who are unlike us, who have far less than us, who have lived with the devastating limits of war and national tragedy. there have been the volunteers who have been on my mind, welcoming and caring for refugees arriving on the beaches so close to this cathedral, and they do one thing, save life at sea. it is not politics, it is simply humanity.
