A documentary that delves into life in the UK's Mormon community has revealed tensions between the generations as a son grapples with his parents' beliefs.

Lindsay Preston, from Ashton-under-Lyne, Greater Manchester, who belongs to the Church of Jesus Christ of Latter-day Saints, appears on Wednesday's episode of Stacey Dooley Sleeps Over on W.

During the programme, she and her husband Mark insist they are not homophobic and say that although homosexual is not a sin in itself, acting on it violates the 'moral standard' of the Mormon church.

However, they clash with their son Adam, 17, who says that it's not a choice to be gay, and tells his father that his views on heaven make absolutely 'zero sense'.

Stacey met with the family as Adam prepares to go on a two-year mission to Zambia where he will try to recruit new members of the church, and will have limited contact with his family.

When quizzed on the church's views on homosexuality by Stacey, Lindsay said: 'We're not homophobic.

'But there are things that, if you were practicing that lifestyle, you wouldn't be able to be baptised, because you're not living the standard of morality that we would expect.

'There are gay members of the church and as long as they aren't practicing that, then everything remains the same.'

Stacey then pondered whether two gay people would be allowed to have sex if they were married, to which she said: 'We don't recognise marriage between same sex couples.

'We believe marriage is between a man and a woman.'

The prompted her 17-year-old son Adam, who is also a devout member of the church, to reply: ' You don't wanna be homophobic do you?'

Her husband Mark defended his wife, insisting: 'I honestly don't think we are homophobic. It's an eternal principle.'

However teenager Adam wasn't convinced, and continued to quiz his parents on their views, arguing: 'It's not something you choose, it's just in your brain.

'It's not really a problem. Well, I don't think it's really a problem.'

Journalist Stacey Dooley quizzed the Preston family on their beliefs, asking whether it would be acceptable for two people to practice homosexuality if they were married

Mark went on to explain that he feels the human race is being 'tried and tested', and believes people will eventually transcend to a hierarchical afterlife.

He said: 'We do believe we're here to be tried and tested and it's not going to be easy.

'We believe that the majority of the world will go to heaven, but there will be different levels.'

Adam Preston, 17, disagreed with the church's viewpoint, and felt that individuals should be embraced for who they are, regardless of their sexuality

His son promptly replied: 'I just don't understand it. That's the thing, it makes zero sense. The reason you gave, that's just a rubbish reason

'God made us to be who we are. Why would he make gay people and say "but you can't really be gay?".'

Stacey then asked Adam whether he felt worried about being asked on his forthcoming Mission about the church's stance on same-sex marriage,.

He confessed: 'Even if I knew God was real, I wouldn't want to be part of that, even if he was homophobic, because you're not gonna wanna be, are you?'

The Preston family are soon to see their eldest son Adam travel nearly 5,000 miles away to Zambia to embark on his Missionary work

At the time of filming, Adam was preparing to travel nearly 5,000 miles away to embark on the Zambia Lusaka Mission in East Africa for two years.

A typical missionary day begins by waking at 6:30 a.m. for personal study followed by appointments, visiting homes or meeting people in the street and other public places, and finishes by 10:30 p.m.

What is a Mission? The Church of Jesus Christ of Latter-day Saints often send out members on a 'Mission' Mormon missionaries can be seen in hundreds of major cities in the world as well as smaller communities Missionaries can be single men between the ages of 18 and 25, single women over the age of 19 or retired couples Their aim is to recruit members for the LDS Church Single men serve missions for two years and single women serve missions for 18 months Advertisement

Missionaries are not allowed to use social media with restricted contact to family and friends, and Adam's mum insisted it's 'really important' for young Mormons to embark on their mission.

She said: 'It's really important that they serve a mission, it's a really difficult thing to do because, as you know, not a lot of people are interested in religion, and it's getting less so.

She continued: 'They're out from 10 till 9 at night. They get a short break for lunch.

'When they're on a mission they won't have their phone on them, they won't have contact, they won't use social media.

'He'll just have a mission phone, which will be used to contact the mission president or other members.

'While it's hard, it is a struggle, but for those that do it, it's a massive growth experience.'

In preparation for his mission, Adam met two oversea Missionaries who have come to the UK from the US and Ghana.

The pair of missionaries, who are refereed to as Elder Miller and Elder Frey, opened up about their experiences, confessing that they've previously had people 'scream in their faces' over their beliefs.

The pair insisted that although some may feel it's 'crazy' for teenagers to abandon their home lives they have faith in their religion

The pair insisted that although some may feel it's 'crazy' for teenagers to abandon their home lives, they believe in the 'blessings' their religion brings, and don't feel as though they've been 'brainwashed'.

Elder Miller said: 'Why I'm here is because I have seen the blessings that come from the message we share from people, not that i'm brainwashed like that, but I've seen it in my own life.'

Elder Frey added: 'I guess 18/19 year old leaving their whole lives behind to do something like this to the outsider is crazy but I don't think I've been brainwashed'.
