Tomorrow will see RTÉ begin broadcasting its first Sunday Mass transmissions directly from churches instead of being produced in studio.
The new broadcasts will be produced by independent production company Scratch Films, which was awarded the contract last October for a three-year period.
The move to have RTÉ's Christian worship content be independently produced is part of RTÉ’s new direction strategy.
RTÉ has broadcast its Christian worship content for over 30 years from its Donnybrook studio.
However, the broadcaster said in October that the existing model meant bringing groups of people from parishes and schools around the country to Dublin, which was a "significant imposition on them with an associated carbon footprint".
Tomorrow’s service will be broadcast live from St Mary’s Church in Navan from 11am.
Archbishop Eamon Martin welcomed the move to broadcast from parishes around the country, calling it "an example of public service broadcasting at its best", adding that those who are housebound or elderly would value the service.
"While we are very grateful for past broadcasts of worship from the RTÉ studio, we believe that sharing the celebration of Mass directly from parishes and from our many beautiful and historic churches will provide a richer and more authentic experience for all concerned."
