John-Paul Ford Rojas writes at The Telegraph:
Dr Williams, 61, will leave at the end of December to take up a new role as Master of Magdalene College, Cambridge next January. The Queen, Supreme Governor of the Church of England, has been informed.
His reign has been plagued by bitter rows over gay clergy and women bishops that have left him struggling to prevent the Church from unravelling.
Explaining his reasons for leaving, Dr Williams admitted that “crisis management” was not his “favourite activity” but denied the rows over homosexuality had “overshadowed everything”.
But he said: “It has certainly been a major nuisance. But in every job that you are in there are controversies and conflicts and this one isn’t going to go away in a hurry. I can’t say that it is a great sense of ‘free at last’.”
Dr Williams said his successor would need the “constitution of an ox and the skin of a rhinoceros”.
From the Archbishop’s website:
It has been an immense privilege to serve as Archbishop of Canterbury over the past decade, and moving on has not been an easy decision. During the time remaining there is much to do, and I ask your prayers and support in this period and beyond. I am abidingly grateful to all those friends and colleagues who have so generously supported Jane and myself in these years, and all the many diverse parishes and communities in the Church of England and the wider Anglican Communion that have brought vision, hope and excitement to my own ministry. I look forward, with that same support and inspiration, to continuing to serve the Church’s mission and witness as best I can in the years ahead.
