It could be a case of expectations versus reality - the expectation of a charismatic kneel to the ground and a kiss on the tarmac, of fanfare and hysteria.
But that was in 1979 and this is now.
Nearly 40 years after Pope John Paul II received an emphatic welcome, Pope Francis is visiting a different Ireland.
The Republic of Ireland today is more secular, far more liberal and, in many cases, angry.
The clerical sex-abuse scandals, the mother-and-baby homes, and the history of a Church covering its tracks has lessened the institution's influence over its Irish flock.
Protesting outside Dublin Castle as the Pope made a quick-stop tour of the city's streets, Savia, a group of survivors and victims of institutional abuse, laid out children's shoes tied in black ribbon in memory of those who had been robbed of their childhood by priests.
Even the country's prime minister, Taoiseach Leo Varadkar, an openly gay man, set aside the pleasantries when he asked the Pope to "bring justice and truth and healing for victims and survivors".
Perhaps it is no wonder that Pope Francis's visit is more of a sombre affair than that of his Polish predecessor.
For those who have been campaigning for abuse victims, some might take solace in the Pope's admission that he was ashamed by the Church's failure to address the "repellent crimes" of sex abuse.
They might also be consoled by the fact he spent 90 minutes in private with eight abuse survivors on Saturday afternoon.
But others might think that is not enough.
Neither referendum had the same tight margins as the divorce referendum in 1995. Both were a landslide in favour of a more liberal order.
While you might still come across the odd Sacred Heart statue in a more traditional home in rural stretches of Ireland, strong faith is less common than it was in 1979.
Catholic Ireland is now home to many who go to Mass for Christmas, weddings and funerals, but generally ignore the Sunday ritual.
Crowds lining the streets of Dublin to greet the Pope on Saturday were one-person deep.
Moving through these crowds was easier than trying to get through the city for the St Patrick's Day parade.
Plenty in the crowd had come from abroad especially for the visit.
While Ireland has also become more international in the last 39 years, as Dubliners wandered past the barriers en route to the shops, it was difficult to grasp the Irish enthusiasm.
At Saturday night's Festival of Families event - complete with performances by world-renowned tenor Andrea Bocelli, country singer Nathan Carter, and acclaimed Irish singer Daniel O'Donnell - the Croke Park stadium of 82,300 was not full to capacity.
And the weather dampened proceedings - if not spirits - on Sunday morning as the Pope visited the Marian shrine at Knock.
Eyes will now be on Dublin's Phoenix Park later on Sunday, to see if crowds will show up for the visit's closing Mass in greater numbers.
In his speech welcoming the Pope, Mr Varadkar said the time had come for Ireland to build a new relationship - "a more mature relationship" - between Church and state.
These words were indicative of the Republic of Ireland's move towards an arms-length relationship with an organisation that once wielded its power over all arms of the state.
