Churches and mosques remained shut over the weekend, but congregations still found a way to connect with their faith.
Religious services were relayed via webcam and radio to stem the spread of Covid-19 and comply with social distancing directives.
After Sunday Mass, which was streamed live from St John's Cathedral in Limerick, Bishop Brendan Leahy admitted: "None of this is easy. It doesn't come naturally to us to isolate, to restrict our movements like this."
In Kilkenny, Bishop Dermot Farrell broadcast from KCLR radio studios.
He told listeners how he had celebrated the funeral Mass of the Diocese of Ossory's oldest retired priest during the week. Just 25 people were present, mainly family.
"It shocked me to think how much our country had changed in a few weeks. The one we were laying to rest had ministered so long in that parish, there were many people - parishioners, priests, and friends - who would have loved to have been present for the funeral Mass, but they could not attend because of the Covid-19 public health emergency," he said.
The Catholic bishops of Munster described the situation as "difficult", but said people have been able to find some comfort and support through Masses streamed online.
Thousands of Muslims across Ireland have also been forced to say prayers at home as the country's mosques remained shut in response to the pandemic.
On the Islamic holy day last Friday, Shaykh Dr Umar Al-Qadri, chair of the Irish Muslim Peace & Integration Council (IMPIC), broadcast via the internet from west Dublin.
He told the Irish Independent the closure of mosques was in line with Islamic jurisprudence in which the protection of human life is a priority.
"We have closed the doors of the mosque and not just for Friday prayer. This particular virus is easily spread. When we pray, we prostrate to the ground. The carpet could transmit the virus. If people gather in the mosque it is highly likely that the virus will be transmitted rapidly among worshippers," he said.
"That is something we have to avoid at this stage."
In the case of death due to Covid-19, the Irish Council of Imams is recommending direct transfer of the body to the cemetery where the funeral prayers will be offered.
Shaykh Al-Qadri said the containment measures meant that many Irish Muslims who had booked to go on pilgrimage to Mecca this year have had to cancel.
Asked about broadcasting Friday prayers via webcam, he said that it is not essential as "in Islam if you cannot attend the Mosque to pray the Friday prayer then you just say the standard afternoon prayer".
As part of the Muslim community's pastoral outreach, Dr Ali Selim, project manager at the Islamic Cultural Centre of Ireland, told the Irish Independent that the centre is providing dry food dishes and hygiene kits in Dublin, Cork, Mullingar, Kilkenny and Mayo, mainly focused on people of 70 years or older.
"We are also delivering orders made by old people," he added.
The Church of Ireland, like the Catholic Church, operates on an all-island basis across 32 counties. Spokesman Peter Cheney said that on March 17 it issued an updated guidance advising the suspension of all public worship services until further notice.
"This guidance applies across the whole island," Mr Cheney said.
Just prior to the decision to suspend services, the Diocese of Down and Dromore's St Patrick's Day service took place largely in open air at Saul, Co Down, and around 50 pilgrims walked together from Saul to Downpatrick.
While a number of Church of Ireland churches remain open for private prayer, this is at the discretion of local clergy.
Funerals and weddings are continuing, Mr Cheney said, but on a small scale and subject to guidance from the diocesan bishop and in compliance with the government's recommendations.
Parishes may choose, at a later date, to hold larger services of thanksgiving or for the renewal of marriage vows when the crisis is over.
