Parish priest Fr Liam Ó hIcí said Liam Miller "completed his life to the full" during the requiem mass for the former Republic of Ireland midfielder who lost his battle with cancer at the age of 36.
The funeral mass took place at the Church of St John the Baptist in Ovens, County Cork, with Roy Keane, Martin O'Neill, Steve Staunton, Denis Irwin, John O'Shea and Kevin Doyle among the mourners.
The ex-Celtic and Manchester United player died on Friday.
"Liam who died so young on Friday night last after he had completed his life to the full," Fr Ó hIcí said.

In the homily Fr Ó hIcí paid tribute to the fortitude Miller displayed battling illness.
"Liam fought his illnesses with the same resilience he played but it was not to be," the priest said, who also spoke of Miller as a man of faith.
Among the gifts brought to the altar during the mass were football jerseys, rosary beads and photos of his family, his First Holy Communion and one of him with team-mates.
"Liam used his talents to the full and in so short a time," the priest said.
"And through that (Liam) gave so much joy to people and also glory to God who gave him those talents and pride to his family."
Mourners heard a roll call of some of the sport's greats who Miller played for including Alex Ferguson, Kenny Dalglish and Giovanni Trapattoni.
"As one might say, follow that," Fr Ó hIcí said.
The funeral mass was held in St John the Baptist Church where Miller was baptised and confirmed and across the road from where he went to school.
Legendary Glasgow Celtic figure Willie McStay said Liam Miller was a joy to work with, and that he will always remember "that wee boy who never gave the ball away and could run all day".
The former Glasgow Celtic player and Head of Youth addressed the congregation gathered and said the Cork native was one of the most promising and sought after talents around when he came to the club and soon won the respect of all he played with.
He described him as having an upright and elegant style and was a boy who loved to play football but also enjoyed the fun and banter that goes with the dressing room.
He said the Miller family would always be part of the Glasgow Celtic family and that Liam would never walk alone.
The President of Ireland, Michael D Higgins was represented by his aide-de-camp Commandant Brian Walsh, while Taoiseach Leo Varadkar was represented by his aide-de-camp Comdt Caroline Burke.
Mr Miller is survived by his wife Clare and three children, Kory, Leo and Belle together with his parents, Billy and Bridie, brothers Sean, Robby, Martin and sister, Suzanne.
