Nardia Foster, a Christian psychologist and former psychology teacher, is speaking after the mental health charity Mind found out through a Freedom of Information request that one in ten people who had been in hospital in England and Wales for mental health problems hadn't received a follow-up appointment within a week - the timeframe they're meant to.
It also reported a majority of health boards in Wales could not provide the information they required.
In a survey Mind conducted of 850 people who'd been in hospital because of mental health conditions, they found people who hadn't received a follow-up within a week were twice as likely to attempt suicide than those who'd received them within a week.
It's prompted the charity to call for mental health follow-up appointments, whether they are in person or over the phone, to always be delivered within 48 hours in order to reduce the chance someone may attempt suicide.
Speaking on Premier's News, Nardia Foster said: "Many of these people are being picked up, they're getting support, but [the answer is] recognising that the support must continue. Letting somebody out of the door doesn't mean the support ends.
"That's where the churches step in, that's where the community needs to step in. What's happened was the Church has been vilified, the community has been vilified, and now these people are dropping through the net."
"We've forgotten the value of life. We've forgotten that each person is special. Until that happens in the system, we are going to have problems."
An example of a Christian practically getting behind Mind's proposal could include visiting or speaking on the phone with a person suffering from mental health problems who's just been discharged from hospital, or praying for them or the NHS.
A Department of Health spokeswoman said: "We know that follow-up treatment is crucial for people with mental health conditions, which is why we have invested £400 million to improve mental health crisis care in the community, allowing more people to be treated closer to home and get the support they need following discharge from hospital.
"Any failure to meet Nice guidelines on follow-up appointments must be taken extremely seriously, and we expect trusts to take action to prevent this."
