Natalie Collins from Christian anti-domestic abuse charity SPARK was speaking as the NSPCC revealed a 75 per cent increase in calls over the last five years of adults concerned that children were suffering or witnessing domestic abuse.
On average ten adults day get in touch with the children's charity about the issue.
Natalie Collins told Premier: "20 years ago there was a real idea that whatever happens in the home is in the home.
"There's a sense that now we're more comfortable in intervening in other people's lives because we have been taught in society in a way that hadn't before been said, that children's safety is a higher priority than offending somebody.
"Obviously now that sounds totally logical - but I think ten, 15, 20 years ago there was a real different attitude in society."
The NSPCC helpline received 3,883 contacts in 2015/16, compared to 2,223 in 2011/12, from people worried about children living in a dangerous household.
In 2015 83 per cent of contacts to the helpline were so serious that counsellors referred them onto external agencies such as the police or social services.
More than half of the children referred by the NSPCC were under the age of six.
Ms Collins added that Christians need to be "praying for women who are in this situation where there is abuse, praying for children, praying for the system - for our politicians, for our structures."
