Micheál Ó Comáin, a herald of arms at the Genealogical Office in Dublin, informs me that the Chief Herald is not taking sides in the fundamental divide between the Church of Ireland and the Roman Catholic Church in Ireland. As reported earlier, the Church of Ireland arms of the Archdiocese of Dublin and Glendalough, that is:
Azure, an episcopal staff in pale or, ensigned with a cross pattée argent, surmounted of a pall of the last, edged and fringed of the second charged with five crosses pattée fitchée sable
must now be differenced by a bordure Or, while the Roman Catholic Archdiocese of Dublin gets the arms without any difference at all. Would this be to suggest that the Roman Catholic Church is more legitimate than the Church of Ireland? Just because the pre-Reformation Church was “Catholic” does not mean that the current Roman Catholic Church is its actual successor – that case could be made just as easily for the Church of Ireland, which possesses most of the pre-Reformation church buildings, and which represents legal institutional continuity, even if most Irish people didn’t become members of it.
No, all that happened is that “a certificate in favour of Cardinal Archbishop Desmond O’Connell ratifying and exemplifying his personal arms impaling the undifferenced diocesan arms was issued during his incumbency [1998-2004]. The diocesan coat appearing on a such a document and duly recorded in the Register of Arms is tantamount to a Confirmation.” In other words, the Catholic Archbishop simply beat the Protestant Archbishop to the registration, forcing the Protestant to difference his archdiocesan arms when he got them confirmed in 2016.
