Sixty years ago today, a young woman spoke about the speed of technological change as she presented the first television broadcast of its kind. She described the moment as a landmark:

“Television has made it possible for many of you to see me in your homes on Christmas Day. My own family often gather round to watch television as they are at this moment, and that is how I imagine you now.”

Six decades on, the presenter has ‘evolved’ somewhat, as has the technology she described.

Back then, who could have imagined that people would one day be watching this on laptops and mobile phones – as some of you are today.

But I’m also struck by something that hasn’t changed. That, whatever the technology, many of you will be watching this at home.

We think of our homes as places of warmth, familiarity and love; of shared stories and memories, which is perhaps why at this time of year so many return to where they grew up.

There is a timeless simplicity to the pull of home.

For many, the idea of “home” reaches beyond a physical building – to a home town or city.

This Christmas, I think of London and Manchester, whose powerful identities shone through over the past twelve months in the face of appalling attacks.

In Manchester, those targeted included children who had gone to see their favourite singer. A few days after the bombing, I had the privilege of meeting some of the young survivors and their parents.

I describe that hospital visit as a “privilege” because the patients I met were an example to us all, showing extraordinary bravery and resilience.

Indeed, many of those who survived the attack came together just days later for a benefit concert.

It was a powerful reclaiming of the ground, and of the city those young people call home.

We expect our homes to be a place of safety – “sanctuary” even – which makes it all the more shocking when the comfort they provide is shattered.

A few weeks ago, The Prince of Wales visited the Caribbean in the aftermath of hurricanes that destroyed entire communities.

And here in London, who can forget the sheer awfulness of the Grenfell Tower fire?

Our thoughts and prayers are with all those who died and those who lost so much; and we are indebted to members of the emergency services who risked their own lives, this past year, saving others.

Many of them, of course, will not be at home today because they are working, to protect us.

Reflecting on these events makes me grateful for the blessings of home and family, and in particular for 70 years of marriage.

I don’t know that anyone had invented the term “platinum” for a 70 wedding anniversary when I was born. You weren’t expected to be around that long.

Even Prince Philip has decided it’s time to slow down a little – having, as he economically put it, “done his bit”.

But I know his support and unique sense of humour will remain as strong as ever, as we enjoy spending time this Christmas with our family and look forward to welcoming new members into it next year.
