The Cabinet is expected to agree today to hold a referendum on same-sex marriage.
Taoiseach Enda Kenny has also committed to outlining his personal position, and that of the Fine Gael party, on the issue.
Minister Michael Noonan said he personally has "no objection" to the principle, and that Ireland had to have a "non-judgemental society, where different lifestyles are not only accepted, but celebrated."
The Constitutional Convention recommended a referendum on the issue when it met over the summer, with the Government agreeing to a four-month deadline to respond - a deadline which has now arrived.
It is expected that the Cabinet will today agree to hold the referendum within the lifetime of the Government, but it is unlikely an exact date will be set this morning.
Fine Gael TD Pat Deering said he thinks the issue will be divisive in the party.
"We've just come through a difficult enough six months after the abortion matter … which has been bruising from a party point of view," he said.
"I would be reluctant at this stage to open old wounds."
Minister Brendan Howlin, however, said it was on the Cabinet agenda, and that he believes a majority of the members would agree with the Constitutional Convention that there should be a referendum.
