Linfield was once regarded as a protestant club for protestant people.
It still draws the vast majority of its support from one side of the community but its squad is one of the most diverse in the Irish League.
Not so long ago the notion of Linfield FC having any association, however tenuous, with the GAA would have also been held to ridicule.
But the Blues have now developed links with the organisation.
Former Strabane Gaelic footballer JP Gallagher and West Belfast man Paul Munster, who also played GAA, told UTV Live Tonight how well they were received when they joined the Blues.
"I like the Gaelic alright and I'd still go to the matches but soccer has always been my first love," said Gallagher.
"Everyone gets on really well irrespective of what religion they are and the banter's great."
Munster lives close to Ulster GAA's Casement Park Headquarters in Andersonstown and he too is enjoying his time at Windsor Park.
"The fans have been brilliant to me and there's never any talk about who you are or what you are - football's the only religion for us all."
Linfield manager David Jeffrey insists that it is the players desire to wear the famous blue shirt, not religious affiliation, which matters most.
"I don't care if they come from Mars. The only thing that concerns me is that players want to wear the shirt. Linfield reflects the changes in society here. But my players just want to play for Linfield and win trophies," he said.
But there were darker times in the club's past.
On Boxing Day 1948, so-called Linfield fans assaulted Belfast Celtic player Jimmy Jones after a game at Windsor Park, leaving him with a broken leg.
That incident ultimately led to Belfast Celtic withdrawing from the Irish League at the end of that season.
In 1990, Linfield played Donegal Celtic in the Irish Cup. The game made headlines around the world for the wrong reasons.
"At half time we had the discussion to whether we were going to go out again. We were afraid of somebody getting killed and at the end of the day it wasn't worth that", Raymond Bonnar told UTV Live Tonight.
Thirty people were injured in some of the worst scenes of sectarian violence involving sport.
"Again that was probably a reflection or mirror image of what was going on in the country at the time. And there were people here on that particular day just intent on trouble. They'd no interest in the game of football", Linfield manager David Jeffrey said.
Sixteen years later the wounds were well and truly healed. In 2006, Linfield played Donegal Celtic at Suffolk Road in west Belfast.
"The warmth, the friendship and the welcome was something else. We had such a fantastic day. It was all about the football", David Jeffrey recalled.
"We were royally treated. It was a good day all round and we remember we won 1-0, so I was pleased about that."
"To have a team like Linfield to come up was unbelievable for the whole community", former Donegal Celtic Manager Paddy Kelly said.
"We got the players together told them this isn't an ordinary team you are playing, this is Linfield football club. The whole day went really, really well apart from the result."
On Tuesday night, the programme looks back at Linfield's first game with Cliftonville at Solitude, after both teams were banned from playing each other there for 28 years.
The feature also includes a look back through the eyes of former Linfield manager Roy Coyle at what came to be known as the 'Battle of Dundalk' in 1979.
