Ireland's church leaders say they're "gravely concerned" at the prospect of abortion legislation being introduced in the North.
During the summer, MPs in the House of Commons voted to decriminalise abortion in Northern Ireland if power-sharing is not restored before 21st October.
In a joint statement, church leaders said they want members to "pray, call for change and to lobby their locally elected representatives".
They claim there is no evidence these change reflect the will of the people as they were not consulted, and that the new rules will be "almost unregulated".
The leaders state: "We recognise that time is short, but that if our devolved institutions are re-established before 21 October, this Westminster based legislation will not be imposed on Northern Ireland.
"Our Northern Ireland political parties have it in their own hands to do something about this.
"They all need to take risks and make the compromises necessary to find an accommodation that will restore the devolved institutions."
The statement is signed by leaders of the Church of Ireland, Presbyterian Church, Methodist Church, Catholic Church and Irish Council of Churches.
In July, British MPs supported an amendment to introduce same-sex marriage in Northern Ireland by 383 votes to 73, while the abortion amendment was backed 332 to 99.
The measures will come into effect unless devolution is restored in the coming weeks.
The last Northern Irish elections were held in March 2017, and efforts to form a new executive have repeatedly stalled since then.
Amnesty International called the abortion vote in Westminster a "significant defining moment for women's rights in Northern Ireland".
Currently, abortion is outlawed in Northern Ireland except for in cases where there is a risk to the life or health of the pregnant woman.
The eighth annual March for Choice demonstration took place in Dublin on Saturday, with campaigners calling for "free, safe and legal abortion access" in the North.
