This afternoon, in St Patrick's Cathedral, Dublin, there will be a service to launch the fifth edition of the Church Hymnal, which has been published by Oxford University Press.
Choirs and congregations from Church of Ireland parishes will join, under the baton of John Dexter, to sing a selection from the new hymnal.
The book will be launched by the BBC broadcaster, Pam Rhodes, and dedicated by the Archbishop of Armagh.
Pam Rhodes, who is well known for her association with the Songs of Praise programme, will speak with some of those who have been involved with the project.
Among those to be interviewed will be Dr Donald Davison, the music editor, pupils from Strandtown Primary School, Belfast, the Bishop of Down and Dromore and Canon Michael Burrows, who were both members of the Hymnal Revision Committee, and Ms June Howard, the committee's honorary secretary.
The Church Hymal is the work of the Hymnal Revision Committee which has been meeting since 1994 under the chairmanship of the recently retired Bishop of Limerick, the Right Rev Edward Darling.
Sing to the Word, a guide to the new hymnal, by Bishop Darling, will be published shortly by Oxford.
The service will begin at 3.00 p.m. and the congregation is invited to a "warm-up" at 2.30 p.m. All are welcome to attend.
Later in the afternoon the Lord Mayor of Dublin, Alderman Maurice Ahern, will officially open the restored guild chapel of St Anne in St Audeon's Church, Cornmarket.
The restoration work has been carried out by Duchas, which will be organising guided tours of the chapel and the parish church, where the vicar is Canon John Crawford.
Next week the Bishop of St David's and his clergy will be in Dublin for a study conference.
Among those who will address them will be the Bishop of Meath and Kildare and the Church of Ireland Historiographer, Dr Kenneth Milne, who will brief the visitors about the historical dimension of the Church of Ireland within the Anglican Communion.
Tomorrow RTE will broadcast a Parish Eucharist from St Nicholas' Church, Adare, where the rector is the Ven Michael Nuttall. In Clane, the Bishop of Meath and Kildare will rededicate the clock tower of the Church of St Michael and All Angels which has been restored in memory of the late Mrs Lily Stewart of Prosperous.
On Monday evening the Bishop of Down and Dromore will institute the Rev Denise Blakely to the incumbency of Carrowdore and Millisle, and on the following evening the Archbishop of Dublin will introduce the Rev Katherine Poulton as Bishop's Curate of the parishes of St George and St Thomas.
On Wednesday the Rev David Johnston will be instituted to the parishes of Sixmilecross and Termonmaguirke by the Archbishop of Armagh.
In Dublin on Thursday morning the annual fair in aid of St Mary's Home for Elderly Ladies will be held in the Royal Hospital, Donnybrook.
In the evening, in Christ Church Cathedral, Therese Timoney and Mark Duley will direct Christ Church Baroque in a performance, using period instruments, of works by Vivaldi, Corelli, Pergolesi and Handel.
The Rev Bernadette Daly has been appointed as Director of Pastoral Studies in the Church of Ireland Theological College.
