Ireland probably has the most explicitly Christian constitution in the world. Its preamble begins: “In the Name of the Most Holy Trinity, from Whom is all authority and to Whom, as our final end, all actions both of men and States must be referred, We, the people of Éire, Humbly acknowledging all our obligations to our Divine Lord, Jesus Christ, Who sustained our fathers through centuries of trial…”
The constitution was adopted early in the 20th century, in 1937. In the 21st century, the Irish have been chipping away at anachronistic relics of Christian sexual morality in their legislation. Same-sex marriage was adopted in 2015 and abortion was legalised in 2018. The government is working on legalising surrogacy.
And now, an all-party parliamentary committee has recommended that assisted dying be legalised for people with a terminal illness—with the usual safeguards. Legal experts believe that legalising the right to die would only require a change in the law and not a constitutional referendum.
