The Unitarian Church on St Stephen's Green in Dublin will hold separate services today to commemorate the dead of 1916 and the Northern Ireland conflict.
At 11.15am members of the congregation and the public will read from the pulpit the names of all who died in Ireland during Easter Week 1916 and afterwards.
At noon the names of more than 3,500 people who died as a result of the conflict in Northern Ireland will be read, ending with Belfast prison officer Adrian Ismay who died last week following a car bomb attack.
Readers this year will include Lord Mayor of Dublin Cllr Críona Ní Dhálaigh, president of the Royal Irish Academy Prof Mary Daly, provost of Trinity College Prof Patrick Prendergast, broadcaster Joe Duffy and members of the Justice for the Forgotten group.
The papal nuncio Archbishop Charles Brown will preside at the liturgical celebration of the Passion of the Lord in Dublin's Pro-Cathedral at 3pm.
At 7.15pm, the ecumenical Walk of Witness involving Dublin's two archbishops will begin in Christ Church Cathedral. Led by Catholic Archbishop Diarmuid Martin and Church of Ireland Archbishop Michael Jackson, who will carry a cross of the ecumencial Taize monastic community, it will proceed down Dame Street to the Pro-Cathedral. It will stop at the GPO for one minute's silent prayer to remember those who died in Easter Week 1916.
