The Pilgrim's Friend Society, which provides care for the elderly in a Christian environment, was speaking after recent figures revealed 500,000 home care visits in a two-year period lasted five minutes or less.
Large workloads and travelling time between each appointment contribute to the short amounts of time.
Charities have raised concerns that vulnerable people are having to choose between being washed or fed because of the lack of time their home carers have.
According to government website, home carers legally should be paid for their travel between appointments as well as the care itself, however charities have said this does not always happen.
The figures have prompted the health watchdog NICE to issue new guidelines, stating that - generally - home help visits should be at least 30 minutes long.
NICE has also said home carers should be allowed more time travel between appointments.
Louise Morse told Premier's News Hour carers do want to give excellent care and spend more time with their patients, but workloads make this difficult.
She said: "Over the years, the money available [for care] has diminished and diminished until its practically not there at all now. And this is what it boils down to, it's actually a lack of money and a growing population of older people with no one else to look after them.
"Churches actually have an amazing opportunity if they would just turn their minds to it, and many are, and reaching people in the community with the kind of help that the Church has always done in the past. I think the Church as an organisation is basically well set to do it.
"Churches are setting up programmes for meeting older people's needs in their communities... I can think of six pastoral workers who are dedicated to doing just that."
