From a "blogging bishop" to a Sun columnist, the race to find the new Archbishop of Canterbury has begun.
There are seven possible contenders for the role, including a former Russian translator for GCHQ and a man who wants to make St George's Day a national holiday.
However ambitious clerics should take note: Dr Williams warned his successor would need “the constitution of an ox and the skin of a rhinoceros."
The new candidate will need to steer the 77 million Anglicans through thorny issues such as same-sex marriage and female bishops.
One contender has already admitted he was “hoping and praying to God” he was not put forward.
Dr Wiliams is certainly a hard act to follow, with the formidable Anglican as notorious for his political commentary as he is for his capricious eyebrows.
So who might be the next head of the Church of England? Check out the front runners below.
Justin Welby, Bishop of Durham
In a nutshell: former oil executive and Old Etonian. ‘The banker bishop’
What goes in his favour? Self depreciating. Once described himself as “one of the thicker bishops in the Church of England.”
Not just interested in theological issues: is also on the parliamentary commission on banking standards investigating the Libor scandal. Backed by Giles Fraser, “the loose cannon”, who writes for the Guardian.
What counts against him? Lack of experience: has only been a Bishop for a year.
Attitudes towards same-sex marriage and female bishops: strongly in favour of female bishops. Opposed to same sex marriage.
Media savvy? Yes (like Semantu, he’s even got a blue tick by his twitter account)
Eyebrow style: inquisitive (not inquisitor, repeat not inquisitor)
Other facts of note: His ancestors were German Jewish immigrants who escaped a 19th-century pogrom and has five children.
Rt Rev Christopher Cocksworth, 53, Bishop of Coventry
In a nutshell: The ‘baby bishop’: youngest ever diocesan bishop and a mere slip of a thing compared with some of the more senior candidates.
What goes in his favour? An evangelist who is liked by liberals. Bookies favourite.
What counts against him? Age before beauty. An unknown quantity on homosexuality and female bishops. Unfortunate name.
Attitudes towards same sex-marriage and female bishops: has skirted around issue.

Eyebrow style: Spectacular (or rather, emphasised by glasses)
Other facts of note: Once cycled round his diocese in five days to meet his congregation.
The Most Rev Dr John Sentamu, 63, Archbishop of York,
In a nutshell: Ugandan hardline archbishop, would be the first black Archbishop of Canterbury if elected.
What goes in his favour? Charismatic, in many ways the natural successor to Dr Williams as the most senior man in the church after Dr Williams.
What counts against him? Marmite personality: some adore his outspoken, hands on nature, while others believe he is too outspoken. His hardline attitude towards same-sex marriage risks isolating the church further. Concerns raised over recent health issues.
Attitudes towards same sex-marriage and female bishops: Supports civil partnership but believes marriage should be between a man and a woman. Has suggested female bishops may work but with some caveats.
Media savvy? Very, although his appearances have sometimes sparked controversy. He once cut up his dog collar live on TV in a protest against Robert Mugabe.

Has a sense of humour on Facebook (see below picture of nuns and balloons)

"When the policeman suddenly realises that a middle-aged bishop is unlikely to be committing some crime, that has not stopped me being stopped and searched.”
Rt Rev James Jones, 64, Bishop of Liverpool
In a nutshell: The outsider: Rowan Williams pipped him to the post in 2003.
What goes in his favour? Praised for his role charing the independent panel into the Hillsborough disaster. Whilst investigating the disaster he kept on his desk a photograph of the stadium at 2.59pm on the day of the tragedy and the names of the 96 people who died.
What counts against him? Poor health: he had heart surgery last year. He is also one of the older bishops.

He since apologised to Dr John and his partner for "adding to their pain and distress". Has pointed out Biblical examples of love between two people of the same gender.
