My family, my wife, our four children and me, lived 10 years in Ireland from 1996 to 2007. We found Irish Masses to be quick: the quickest I went to was 33 minutes, but 40 minutes or less is the norm. That includes any singing. Lectors get to the altar quick: they don’t wait for a long pause before getting up there and doing the readings. The homily is almost always heartfelt and makes a lasting impression. Maybe it is because Irish people are so articulate and eloquent.
I remember my Dad used to say that if Mass went over 40 minutes, the Irish would start heading for the exit door, and he was born and reared in Iowa!
Almost everyone does the half-sitting kneel, even young healthy people.
The people tend to say the “Through Him, with Him and in Him” prayer with the priest. The priests don’t comment on the practice, but have tried to get it halted by singing the prayer. Irish congregations don’t much like to sing, so that is effective!
The Creed has two small wording differences. Christ “…suffered death and was buried. On the third day He rose again, in accordance with the Scriptures.” not “…suffered, died and was buried. On the third day, He rose again, in fulfillment of the Scriptures.”
In many parishes, old men sit in the back of church, and you can hear their voices rumbling during their conversations throughout Mass. They stop talking and even take off their caps and kneel at the Consecration, though. In 1983 my family and I went to Mass and were surprised to see women and girls on one side of the center aisle, men and boys on the other.
In 1971 I was on my way to Mass in another small town and saw many men and older boys all outside, strung across down the front path, out on the street, some leaning up against shop windows across the street, smoking and conversing. However, at the sound of the consecration bells, all hats came off, and all knelt. Conversation resumed at the end of the consecration.
I wonder if the men outside is a vestige of the day when the church space was too small to allow women and children and men and boys inside to shelter, and the men remained in the weather out of chivalry.
