The Archbishop of Canterbury Justin Welby has waded into the row over energy prices, warning that the latest wave of hikes looks "inexplicable" and that providers should behave morally.
Welby insisted the Big Six companies should be "conscious of their social obligations", and "behave with generosity and not merely to maximise opportunity".
The intervention, in an interview with the Mail on Sunday, came after British Gas followed in the footsteps of SSE by announcing a 9.2% increase in prices.
The head of the Church of England said: "I can understand people being angry about it, because having spent years on a low income as a clergyman I know what it is like when your household budget is blown apart by a significant extra fuel bill and your anxiety levels become very high."
The Archbishop of Canterbury has warned MPs not to rush their decision on whether to vote for military intervention in the Syria conflict.
Ahead of tomorrow's early return to Parliament, the Most Rev Justin Welby said he feared the possible consequences of intervention, saying they were "beyond description and horrible".
He told the Daily Telegraph: "I have had a lot of conversations with people in the region.
"I think the overwhelming sense is of a really moving and terrible sense of fear about what might come out of, what might be happening in the next few weeks - not predicated on people doing one thing or people doing another, just a sense that this a terribly, terribly dangerous time."
However, the Archbishop acknowledged that the Government was better informed than he was, making clear that he had no sense that politicians were "slavering" to "unleash the dogs of war".
The Archbishop of Canterbury's decision to turn down the role of vice-patron of the RSPCA will set back an organisation that has endured some negative recent press.
The animal charity has been accused of being heavy-handed in its approach to pet-owners and of allegedly pursuing criminal convictions to increase its revenue.
It was also accused of wasting public donations by spending £326,000 in pursuing legal action against fox hunters in the Cotswolds last year.
A spokeswoman for Lambeth Palace has explained the Archbishop of Canterbury's decision not to follow his predecessors in accepting the role of vice-patron of the RSPCA.
Since taking office in March this year, the Archbishop has received many kind invitations to patron a large variety of charities and good causes. Each invitation has been an honour, and in an ideal world he would like to accept them all.
However, in light of the sheer volume of the requests the Archbishop receives, and the many pressures on his time and resources, he has reluctantly decided to restrict his patronage to a manageable number of organisations, based on where he feels his support could be most beneficial.
She added: "Nevertheless, the Archbishop has enormous admiration for the RSPCA and hopes to see its work thrive long into the future."
The Archbishop of Canterbury has broken with tradition and turned down a post as vice-patron of the RSPCA, which has faced criticism for its recent bullish pursuit of animal welfare issues.
The animal charity, which was founded by an Anglican priest in 1824, has been accused of wasting donations on legal action.
Lambeth Palace said the Most Rev Justin Welby has "enormous admiration" for the RSPCA but had declined the invitation as he has "reluctantly decided to restrict his patronage".
The Archbishop of Canterbury has told Wonga that the Church of England wants to "compete" it out of existence as part of its plans to expand credit unions as an alternative to payday lenders.
The Most Rev Justin Welby told Total Politics magazine he had delivered the message to Errol Damelin, chief executive of Wonga, one of Britain's best-known payday lenders, during a "very good conversation".
“I’ve met the head of Wonga and I’ve had a very good conversation and I said to him quite bluntly we’re not in the business of trying to legislate you out of existence, we’re trying to compete you out of existence.” He flashes that smile again. “He’s a businessman; he took that well.”
The Archbishop of Canterbury announced a campaign to stamp out homophobic bullying in Church of England schools as he warned the faithful of a "revolution" in attitudes to sexuality in society.
He told members of the Church of England's General Synod: "We may or may not like it, but we must accept that there is a revolution in the area of sexuality and we have not yet fully heard it.
"The majority of the population rightly detests homophobic behaviour or anything that looks like it and sometimes they look at us and see what they don't like.
"With nearly a million children educated in our schools we not only must demonstrate a profound commitment to stamp out such stereotyping and bullying but we must also take action".
Pope Francis spoke about shared hopes for social justice as he welcomed the Archbishop of Canterbury the Most Rev Justin Welby to the Vatican for the first time.
Mr Welby was enthroned as Archbishop of Canterbury, head of the Church of England, and leader of the worldwide Anglican Communion, in March, days after the inauguration of Pope Francis.
The Pope said the closeness of their inaugurations meant that they always had a "particular reason to support one another in prayer".
He added: "Among our tasks as witnesses to the love of Christ is that of giving a voice to the cry of the poor, so that they are not abandoned to the laws of an economy that seems at times to treat people as mere consumers."
Mr Welby has spoken of the inspiration he draws from Catholic social teaching.
The Archbishop said in an address after their meeting: "We must love those who seek to oppose us, and love above all those tossed aside - even whole nations - by the present crises around the world."
Mr Welby was accompanied on his visit to the Vatican by the Most Rev Vincent Nichols, Archbishop of Westminster and leader of Roman Catholics in England and Wales.
Earlier, Mr Welby, who was visiting Rome with his wife Caroline, visited the excavations beneath St Peter's Basilica to pray at the tomb of St Peter.
He also prayed before the tomb of the late Pope, Blessed John Paul II, who died in 2005.
Pope Francis has welcomed the Archbishop of Canterbury the Most Rev Justin Welby in Rome. It's the first time the two church leaders have met.
The leader of the Roman Catholic Church said the two men shared a common desire for social justice, peace and the promotion of Christian values in areas such as marriage.
The Vatican's announced that Pope Francis is to meet the Archbishop of Canterbury for the first time later this week.
The Most Rev Justin Welby will be in Rome to visit the head of the worldwide Catholic Church on Friday.
The Vatican said the two clerics have shared interests in global justice, ethical regulation of financial markets and conflict resolution.
Earlier in the day, the Most Rev Welby will visit the excavations beneath St Peter's Basilica to pray at the tomb of St Peter, as his predecessor Dr Rowan Williams did on his first visit to Rome.
