The government earlier outlined what new laws they'd like to see, including abortion without restrictions for up to 12 weeks.
The Government has published a six-page policy paper on abortion, setting out its plans for abortion legislation provided the upcoming referendum results in the repeal of the Eighth Amendment. Global Positioning System and other health practitioners will be licensed to prescribe the abortion pill.
The bill to hold a referendum on the Eighth Amendment, which provides for the equal right to life of the mother and the unborn, will be introduced in the Dáil today.
If the Eighth Amendment is repealed, women will be able to have an abortion up to 12 weeks into their pregnancy regulated through a GP-led service.
Currently, terminations are only allowed in the Irish Republic when the life of the mother is at risk, including from suicide, and the maximum penalty for accessing an illegal abortion is 14 years in prison.
The exact wording would be: "Provision may be made by law for the regulation of termination of pregnancy".
Ireland's health minister, Simon Harris, said on Friday that a yes vote in May would represent a "quantum leap from our position today, where have one of the most restrictive regimes, similar to Saudi Arabia". The referendum, slated for the end of May, will be putting a possible repeal of the Eighth Amendment to the Irish people.
"This referendum is about asking our citizens to allow women to make major decisions for themselves".
A change to the law would be a monumental step for Ireland, where since 1983 it has been estimated that 170,000 women have left the country to terminate pregnancies.
The bishops said in a statement: "We believe that the deletion or amendment of this article can have no other effect than to expose unborn children to greater risk and that it would not bring about any benefit for the life or health of women in Ireland".
"The minute an Irish woman becomes pregnant, she no longer has destiny over her own health care", Mr Kelleher said.
The move comes after a Supreme Court ruling on Wednesday that protections for the unborn child offered under the state's constitution do not extend beyond the right to life.
The debate is due on continue today until 4pm.
