In a statement agreed at their summer meeting last week, the bishops said some public representatives seemed "determined at all costs to widen the scope of the present law".
Its publication coincides with an announcement by Sinn Féin leader Mary Lou McDonald that the party will move legislation next week to remove the current three-day mandatory waiting period.
The Bishops' Conference expressed "gratitude" to public representatives who had "courageously affirmed the right to life of the unborn".
Marking the Catholic Church’s annual 'Day for Life’, due to take place next Sunday, the bishops questioned why there had been "no attempt" to find out why 90% of abortions take place in the first 12 weeks.
"Neither the State, nor the mainstream media, seem to have any interest in exploring what leads women to choose abortion or what happens to them afterwards," it said.
They quoted a recent address by Pope Leo XIV, who told the Spanish parliament that human life must be recognised and safeguarded from conception to its natural end, in every circumstance of its existence.
Last month, the National Women’s Council marked the eighth-year anniversary of the referendum on abortion by calling for "compassionate care" to be given to any woman seeking abortion services in her locality.
A bill was also introduced by the Social Democrats to address what the party described as deficiencies in the Termination of Pregnancy Act 2018.
The party argued that a review of the legislation - commissioned by the Government - proved that Ireland's abortion laws were failing women.
The bill sought to abolish the three-day wait period, end the criminalisation of medical professionals, and expand the grounds for fatal foetal abnormality.
However, it was defeated in the Dáil by 85 votes to 30.
