Sixty Church of England Bishops have joined with other faith leaders to call for a rethink the Government's two-child limit on benefits.
They have signed a joint letter alongside representatives from other churches as well as Jewish and Muslim organisations.
The letter published in The Times argues that the policy - which restricts the level of financial support given to households with more than two children - is trapping families in poverty.
It coincides with the publication of a new report from the End Child Poverty coalition assessing the impact of the limit, which was introduced a year ago.
The Bishop of Durham, a signatory to the letter said: "It is simply not right that some children get support and others don't.
"We share a moral responsibility to make sure that everyone in our country has a decent standard of living and the same chances in life, no matter who they are or where they come from."
More details can be found in an announcement from the End Child Poverty coalition.
The letter is published here.
The report, entitled Unhappy Birthday: the two-child limit at one year, is also published today.
the full text of the letter reads:
Sir, Today the “two-child limit” policy, which restricts tax credit and universal credit to the first two children in a family, has been in place for a year. The policy is making it harder for parents to achieve a stable and resilient family life. By 2021, 640,000 families will have been affected. Most are low-earning working families, most have three children and some will have made decisions about family size when they were able to support children through earnings alone, but later claimed tax credits or universal credit after bereavement, redundancy, separation, disability, illness or simply low pay.
The policy is expected to tip an estimated extra 200,000 children into poverty. It also conveys the regrettable message that some children matter less than others, depending on their place in the sibling birth order.
It is a grave concern that there are likely to be mothers who will face an invidious choice between poverty and terminating an unplanned pregnancy.
Children are a private joy and a public good. They are all equally deserving of subsistence support.
