The call comes following the UK's decision to leave the EU as well as various shootings against both white and black men in America and the terror attack in Nice.
Speaking to Premier, Daniel Singleton from Faith Action UK said: "It's worthwhile looking at the things that unite us, and the things that bring us together.
"Despite some of the headlines, some of the noise, actually the United Kingdom is a place that people have been able to come to for a place of tolerance, a place of sanctuary, and so we pick out some of those things."
Christian MPs have put their name to a number of requests that the UK stay a united nation.
They've asked:
- That the United Kingdom has been and will continue to be a place of tolerance and sanctuary;
- That this nation has been and will continue to be at the forefront of the development of democracy, rights and freedom, that we are proud of these traditions, and that they are our most lasting export;
- That we have been and will continue to be a dynamic nation where many settle and play an important part in our economy and cultural life;
- That we have a hope in our nation; that the United Kingdom continues to have a positive role to play in the world, and;
- That we continue to have purpose to benefit not only the people of the United Kingdom, but also of Europe, the Commonwealth and the rest of the world.
The letter says: "the reverberating context of the economic crash of 2008 and the growth of terrorism, crisis and wars in recent years have resulted in a great movement of people, which has led to distant problems rippling into our local settings.
"The European Referendum campaign and its aftermath have served as a lightning rod, and the result is great concern about uncertainty and intolerance."
"Faith groups are often the very glue of society; they provide a place for people to come together, they seek out solutions, and they provide hope.
"We want to affirm these values of community and hope for the United Kingdom today."
Daniel Singleton told Premier it is significant that the All-Party Parliamentary Group on Faith and Society issued the statement.
He said: "Because of the relationship with have with as a group of people... and because we're looking at what good can be contributed to society, it felt like a good opportunity to bring this statement, these things, these words of hope together.
"Thankfulness is a great starting point and once we start from that individual basis and look to our families, people around us, the provision of work, homes - and all those kind of things."
