    The Death of Catholic Ireland, Should We Celebrate or Mourn?
    Niall Boylan


New figures suggest Ireland’s relationship with the Catholic Church is continuing to change dramatically, with the annual number of Catholic baptisms across the island falling by around **30% over the past decade**.

In this episode, Niall speaks to **Dr Tom Finegan, Chairman of The Iona Institute**, whose organisation compiled the new figures, and **Michael Nugent of Atheist Ireland**, to debate what is driving the decline and what it could mean for Irish society.

The Iona Institute says the fall is not simply about people abandoning religion. Births across the island have fallen by almost **19% over the same period**, with the organisation estimating that declining birth rates account for roughly 60% of the reduction in baptisms, while increasing secularisation accounts for the remainder.

But the Census figures also show a significant generational shift. In 2016, **78.3% of children aged 0 to 4 were recorded as Catholic**, compared with **65.4% in 2022**. Over the same period, the proportion recorded as having **no religion rose from 9.2% to 15.6%**.

There are also striking regional differences. Baptisms have fallen by almost **40% in Dublin**, more than **40% in the Diocese of Meath**, and almost **38% in Down & Connor**, while some more rural dioceses have experienced much smaller declines.

Tom Finegan argues that despite declining Mass attendance and increasing secularisation, **“cultural Catholicism” remains a significant force in Ireland**, with large numbers of parents still identifying as Catholic and choosing baptism for their children.

Michael Nugent offers a very different perspective, examining whether the decline represents Ireland becoming a genuinely more secular society, whether religion should continue to have such an influence over schools and public institutions, and whether traditional religious identity is gradually being replaced by a society where people increasingly define their morality and values without reference to a Church.

Niall asks whether Ireland is simply witnessing the natural decline of an institution that once held enormous power, or whether something important could be lost with it.

**Does society need religion to provide community, morality and a sense of belonging? Can those things exist just as strongly without God? And when cultural Catholicism eventually fades, if it does, what takes its place?**

A lively debate about faith, atheism, falling birth rates and the changing face of modern Ireland.
