Richard Dawkins has said that Catholics who do not believe in transubstantiation - the doctrine that the bread and wine become Christ's body and blood during the Mass - should admit that they do not truly follow the faith.
The atheist author and evolutionary biologist made the remarks in Dublin, during a public interview as part of the city's Writers Festival.
The Irish Times newspaper had run a poll with Ipsos/MRBI which found that 62 per cent of Catholics said the bread and wine "only represents" the body and blood of Christ. By contrast, 26 per cent said that they believed it physically transformed.
“If they don’t believe in transubstantiation then they are not Roman Catholics,” Dawkins told the audience in the National Concert Hall. “If they are honest they should say they are no longer Roman Catholics.” Asked about the results of the poll, he said: “I wouldn’t hold back on the ridicule”.
Dawkins's comments provoked a riposte from columnist John Waters  in the Irish Times about the "ideological smugness" of those questioned in the poll. He wrote:
Does “rationality” involve a requirement to understand the processes you claim to believe in or trust? If so, how many people could tell you, off the top of their heads, that the margin of error in any particular aspect of an opinion poll is calculated by multiplying by two the square root of the result obtained when the quantum at issue is multiplied by 100 minus itself and the answer divided by the sample? Give me transubstantiation any day – much easier on brain, mind and reason.
Dawkins's comments on the situation in Ireland follow similar remarks on the religiosity of Britain. In his guest-edit of the New Statesman magazine in December 2011, Dawkins wrote  about the findings of a UK poll commissioned by the Richard Dawkins Foundation for Reason and Science which showed that 54 per cent of those surveyed described themselves as Christian. He described them as "Census Christians", for only a third ticked the box because of their religious beliefs.
The bottom line is that anybody who advocates a strong place for religion in government cannot get away with claiming that ours is numerically a Christian country as a basis for giving religion privileged influence. This conclusion is further borne out by part two of our Ipsos MORI survey. Census Christians were asked explicitly about their attitudes to various social issues as well as their views on religion in public life. Seventy-four per cent of them said that religion should not have special influence on public policy. Only 12 per cent thought it should. Only 2 per cent disagreed with the statement that the law should apply to everyone equally regardless of their religious beliefs (so much for the Archbishop of Canterbury's opinion that sharia law in Britain is "unavoidable", and for attempts to exempt Christians from compliance with equalities legislation). More Census Christians oppose than support the idea of the UK having an official state religion, and the same applies to the presence of bishops in the House of Lords.
Less than a quarter of Census Christians think state schools should teach children a religious belief. Sixty-one per cent support equal rights for gay people and 59 per cent support assisted suicide for the terminally ill, given certain safeguards. And for those MPs worried about re-election and the need to appeal to the allegedly powerful Christian lobby, 78 per cent of Census Christians say that Christianity has no or not much influence on how they vote.
