There have been regular calls for it to be scrapped, but now TDs may be forced to stand for a prayer at the start of each day the house sits.
The Government Chief Whip, Regina Doherty, has proposed that "All members present shall stand while the prayer is being read, and when it is concluded, members shall remain standing for 30 seconds of silent reflection."
Solidarity TD for Dublin West Ruth Coppinger described the idea as "baffling" and a "violation of people's freedom of religion and freedom of conscience."
"Are TDs who are not Christians to stand outside the door each day if they don't want to take part? Will the Ceann Comhairle suspend TDs for not standing for prayer each morning?", she asked.
Census results from last year, which were released last week, show that there has been a 74% rise in just 5 years in the number of people that have no religion.
Not only do Solidarity TDs not want to stand for the daily prayer, they have submitted an amendment to the motion so that TDs will have opportunity to vote on having no prayer at all.
