The Archbishops of Canterbury and York are urging people to reach out to others during the current period of national mourning.
In an open letter, Most Rev Justin Welby and Most Rev Stephen Cottrell encouraged people to offer support and company to those who might be finding this weekend especially difficult.
They said the Queen's funeral should be an event that unites people, in line with the Queen's legacy of bringing people together.
The letter reads: “On Monday the country will take part in the biggest act of collective grieving in our history.
“It will have a profound impact on many of us. Some may feel the distress of the loss of Her Majesty directly, someone who - even if we didn’t know her ourselves - played a role in so many of our lives and who came to symbolise the best of our country. For others, this public grief may trigger our own private grief for those we have loved and lost.
“Grief is a natural process. Something we must endure in order to come out of the other side. But we know it can also create huge pain and if not managed well can lead people towards isolation and depression.
“That’s why we are asking everyone to do their bit this weekend to make sure that no one has to grieve alone. We urge companies, councils and public spaces to do whatever they can to open up places where people can be together. And even more importantly, we urge all of us to reach out to neighbours, friends, anyone who might find this moment difficult.
“Invite them to watch it together, raise a glass to Her Majesty or someone we’ve lost, or simply just be together.
“The Queen has many legacies, but one of the most important is her work in bringing people together. It would be fitting that her funeral might do the same.”
The letter was organised by the Together Coalition, chaired by the Archbishop of Canterbury and backed by groups including the Football Association, the Federation of Small Businesses, UK Sport, the Royal Voluntary Service, Rotary, Marie Curie, Saint John Ambulance, the Jo Cox Foundation and many more.
