In a sermon broadcast live on BBC Radio 4’s Sunday Worship (Sunday, 26 February 2012), Archbishop Rowan Williams preached on the theme of freedom – what it means to be free and how we can achieve the true freedom ‘to be what we most deeply are’. Speaking on the first Sunday in Lent at King’s School Canterbury, Dr Williams drew on the life of Dietrich Bonhoeffer, describing the letters which Bonhoeffer wrote to his family and close friends while in prison in Nazi Germany as ‘one of the greatest treasures of modern Christianity’ and focusing on his thoughts on freedom which are so prevalent in his writings.
