Confirmation and First Communion services will be postponed in Dublin if the capital moves to level three of coronavirus restrictions.
As part of level three restrictions, places of worship will once again largely be closed to the public.
While weddings and funerals could still take place with up to 25 attendees, other services would have to be broadcast online.
In a notice to churches today, the Archdiocese of Dublin said: "It is likely that places of worship will remain closed from midnight tonight, except for private prayer, weddings and funerals.
"Effectively this places Churches in the position they were before the reopening earlier this summer, or as the situation was in counties Kildare and Laois early this month.
"Confirmation and First Communion services will therefore not be possible during this period and will have to be postponed."
Last week, the Acting Chief Medical Officer Dr Ronan Glynn warned that communion and christening parties in households 'need to be stopped' for the next few weeks wherever possible because of the surge in COVID-19 cases.
The Government is set to announce new restrictions for the capital this evening, with Cabinet now considering whether to ban indoor dining in restaurants and pubs for the next few weeks.
