'Change is in the air': What do Christians in Saudi Arabia think of the reforming Crown Prince?

Saudi Arabia's crown prince will meet Theresa May today as part of a three-day visit to the UK where he hopes to promote his economic reforms as well as his PR image as a moderniser.

The 32-year-old Mohammed bin Salman is considered the presumptive heir to the 82-year-old King Salman and it will be his first visit to the UK since taking up the role of crown prince last year. As well as meetings with the prime minister and the heads of MI5 and MI6, he will have lunch with the Queen and dinner with Prince Charles and the Duke of Cambridge.

However he is expected to face noisy protesters outside Downing Street for his country's role in the Yemen conflict, which the United Nations has branded 'the world's worst humanitarian disaster for 50 years'. The war has killed an estimated 10,000 people with 8.3 million people depending on food aid and 400,000 children have life-threatening levels of malnutrition.

Saudi-backed airstrikes, supported by the UK and US, are battling the rebel Houthi movement, which is backed by Iran.

The prince is attempting to move Saudi Arabia's economy away from a reliance on oil and is instilling sweeping reforms that included arresting a number of senior politicians on charges of corruption last year. He is also credited for lifting the ban on women driving and is hoping to promote his Vision 2030 plan while in the UK.

However questions are also being raised about Saudi Arabia's tolerance of other religions.

The persecution charity Open Doors ranks the Islamic country the 12th worst to be a Christian in the world.

However a number of Christians in Saudi Arabia, most of whom are migrant workers, are optimistic about their prospects under the new crown prince.

'Change is in the air. That is for sure,' one Western Christian working in Saudi Arabia told the charity. 'Everything is changing. Some people are more open to the gospel, but others are radicalising.

'This is a crossroads. If it works, it will bring huge change and more freedom to this country. If it fails, Saudi might be the next Yemen – only worse. If the fundamentalists win the battle that is now being fought behind the curtains and spark a civil war, this place will go back to the dark ages. So, this is either going to be a huge awakening or it will be one of the biggest bloodbaths in history.'

Another said that with Mohammed bin Salman's focus on reforming the economy and tackling corruption, targeting Christians is no longer a focus.

'Christians are plankton compared to the whales that are now being hunted. So, they simply don't have time to care. As long as believers keep their heads low and don't get themselves reported in the government, they will be fine,' she told Open Doors.

However not everyone is optimistic about the widespread changes.

ReutersThe Saudi Crown Prince has taken out adverts in the Guardian, the Times and the Financial Times newspapers as he seeks to promote his image as a moderniser.

'Change can lead to disruption. No-one knows what will happen if large groups of people start feeling left behind in their own country,' warned one man.

And despite promises to return the kingdom to a more 'moderate, balanced Islam that is open to the world and to all religions and all traditions and peoples', all Saudis are still considered Muslims and conversion to another religion is punishable by death.

Most converts are forced to keep their newfound faith a complete secret from their families and places of worship for non-Islamic religions are banned.

However Open Doors insists that despite the ongoing pressure the 'numbers of Christians are growing'. What is not yet clear is whether the crown prince's reforms will include an easing of laws restricting religious freedom and freedom of expression.
