Christians do not say that people should be reduced merely to what they can produce or what they can buy - that we should let the weak go under and only the strong survive. No, we say, 'Do to others what you would have them do unto you.'
The British economy of the future must be built not on the shifting sands of boom and bust, but on the bedrock of prudent and wise economic management for the long term. It is only these firm foundations that we can raise Britain's underlying economic performance.
To my astonishment, everything that I had assumed was now questioned by the findings. What started off as a search for identity that appeared to be purely Scottish in origin ended up as a discovery of my migrant roots - indeed an understanding that almost all of our families, at some stage, have been migrants - and my European roots.
The motto of the old order in the City of London was, 'My word is my bond,' but the financial crisis revealed a culture quite alien to that heritage. The stewards of people's money were revealed to have been speculators with it.
While you cannot deliver policies without principles, you cannot deliver principles without having power. You have quickly to move to a stage where, emphasising your principles, you build a programme, then call for popular support.
We must understand that the British public's relationship with Europe is - and always has been, the sporting arena aside - about the benefits we can achieve in jobs, security, and quality of life from membership and how these benefits outweigh any disadvantages.
I had to deal with terrorist finance. And we had to, if you like, ensure that the accounts of people who were guilty of terrorist finance or using their accounts for terrorist finance were closed down. So we had to do asset freezing.
I have to say that if our global alliances are going to be alliances with Hezbollah and Hamas and Hugo Chavez's Venezuela and Vladimir Putin's Russia, there is absolutely no chance of building a world-wide alliance that can deal with poverty and inequality and climate change and financial instability, and we've got to face up to that fact.
We are being tough in saying it is a duty on the unemployed in future not only to be available for work - and not to shirk work - but also to get the skills for work. That is a new duty we are introducing.
The best way of realising our high ideals is to show that we have an alternative in government that is credible, that is radical, and is electable - is neither a pale imitation of what the Tories offer nor is it the route to being a party of permanent protest rather than a party of government.
Take, therefore, what modern technology is capable of: the power of our moral sense allied to the power of communications and our ability to organize internationally.That, in my view, gives us the first opportunity as a community to fundamentally change the world.
Do you think that I or anybody else who cares about the NHS would stand by and do nothing if we thought the NHS was going to be privatised in Scotland and its funds were going to be cut? Would we stand back and do nothing without a fight? Of course not.
So another challenge for our generation is to create global institutions that reflect our ideas of fairness and responsibility, not the ideas that were the basis of the last stage of financial development over these recent years.
I'm all for greater co-operation between Europe and America because I think that sometimes we've missed out on the benefits that transatlantic trade could give both continents, and I've been pressing this since 1997.
Other prime ministers leave office and stay in London. I have come back with my whole family to Fife. This is where they are being brought up. It is better for them and better for me. It's great to see more of the kids.
You need in the long run for stability, for economic growth, for jobs, as well as for financial stability, global economic institutions that make sure that growth to be sustained has to be shared, and are built on the principle that the prosperity of this world is indivisible.
If our economies are to flourish, if global poverty is to be banished, and if the wellbeing of the world's people enhanced - not just in this generation but in succeeding generations - we must make sure we take care of the natural environment and resources on which our economic activity depends.
