President Michael D Higgins has led mourners at a mass of thanksgiving in Dublin this morning for the life of Fr Alec Reid.
The Redemptorist priest, who will be remembered for his influential role in the Northern Ireland peace process, died on Friday at the age of 82.
President Higgins and his wife Sabina joined relatives of Fr Reid, as well as political figures and members of the religious community, to remember the life of the priest.
The Taoiseach was represented by his aide-de-camp.
Also in attendance were Sinn Féin President Gerry Adams and deputy leader Mary Lou McDonald, as well as former minister for foreign affairs Dermot Ahern.
Reverend Dr Harold Good, who was a witness to the decommissioning of IRA arms along with Fr Reid, was also among the mourners.
In his homily, Fr Michael Kelleher said Fr Reid saw himself as a servant of Christ in a situation of conflict.
Fr Reid's remains will be taken to Clonard Church in Belfast later today where he will repose today and tomorrow.
An ecumenical service of gratitude for Fr Reid's life and ministry in Clonard Church will take place tomorrow evening, followed by funeral mass on Wednesday.
