The Most Rev Justin Welby warned of the dangers of abandoning more than 1,000 years of Christianity during his first sermon as Archbishop.
A new chapter in the history of the Church of England began today as Justin Welby was anointed leader of the divided congregation.
The Bishop of Durham will be officially unveiled as the new Archbishop of Canterbury today.
The Archbishop of Canterbury Justin Welby has addressed a service to mark the 60th anniversary of the Queen's Coronation at Westminster Abbey.
He told the congregation: "A nation watched. It was the first time the whole nation had watched anything as it happened. But this they saw.
"Pomp and ceremony on a rainy June day, all so very British, wrapped in time and custom
The Archbishop also said that at the 1953 ceremony, the Queen knelt at the abbey's altar and prayed.
"We do not know what was prayed. Her Majesty knelt at the beginning of a path of demanding devotion and utter self-sacrifice, a path she did not choose, yet to which she was called by God.
"Today we celebrate sixty years of whole-hearted commitment and faithfulness".
George Parker, political editor of the Financial Times, asked during the interview on BBC Radio 4's The Week in Westminster whether the Archbishop of Canterbury saw it as part of his mission to try to inject more morality into British financial life.
My key mission is to lead the church in worshipping Jesus Christ and encouraging people to believe in him and follow him. That's my mission.
The Christian gospel has always had strong social implications and one of them is around the common good and it's one of the key areas in which the Church of England focuses, and so issues of how the City of London, which is so important and so full of very gifted people, how that behaves in relation to the common good is very key, not to the whole thing that I'm about or the church is about, but to how we express the implications of that in day to day life.
The Archbishop denied a suggestion that he meant that the bank to be recapitalised was the Royal Bank of Scotland, saying he would not name a bank.
The Rt Rev Justin Welby has warned Britain's economic activity levels are below where the country was over five years ago.
The new Archbishop of Canterbury's comments follow an interview on Monday in which he stated that the UK's is in an economic depression and could take a generation to recover.
Historically depressions have been recognised as lengthy periods in which the economy did not get back to its previous level of activity before a recession set in. So 1929 to 1932 is the great example. There was a big one towards the end of the 19th century.
We are still significantly below where we were in 2007 in terms of economic activity, of GDP, and that's quite a long time of being below.
Now, I'm not pointing any fingers at anyone in particular and saying it's so and so's fault or so and so's fault, it's simply a measurable fact coming from the national statistics.
It's very much (more) noticeable in London, I have to say, than in the north east where I was living previously. Do I mind ruffling feathers? I think I do mind ruffling feathers, I don't like ruffling feathers - but sometimes feathers get ruffled. I mean that's life.
The Rt Rev Justin Welby, who took over the role last month, returned to the theme of the country's financial woes in a radio interview following his warning on Monday that Britain is in an economic depression and could take a generation to recover.
He said then that it would take something "very major" to restore confidence and drag the country out of the mire. He suggested the Government may need to recapitalise at least one major bank, and urged the creation of regional banks.
Asked on BBC Radio 4's The Week in Westminster whether he minded ruffling a few feathers, he said: "I don't know if it annoyed people in Number 10. They haven't said anything here. I mean they probably would have preferred it not said."
The Archbishop of Canterbury said: "It was with sadness that I heard the news of the death of Baroness Thatcher and my prayers are with her son and daughter, her grandchildren, family and friends.
"It is right that today we give thanks for a life devoted to public service, acknowledging also the faith that inspired and sustained her.”
Easter Sunday represents a new beginning for Christians, but today had an even stronger sense of renewal for Anglicans and Catholics.
Both have new leaders just settling into their roles and it's today that their messages tend to reach the widest audience of the year.

The newly-enthroned Archbishop of Canterbury Justin Welby has offered to meet human rights campaigner Peter Tatchell to discuss his views on same-sex marriage.
He thanked Mr Tatchell for his "very thoughtful letter" in which the campaigner criticised him as being "homophobic" for supporting a legal ban on same-sex marriage.
The Archbishop wrote, "It requires much thought and the points it makes are powerful. I would like to explain what I think to you without the mediation of the press, and listen to you in return”.
Mr Tatchell said he was "surprised and delighted" by the offer. “I commend Justin. His swift, personal reply is laudable, especially given how busy he is with his enthronement and with Easter next week", he added.
