ACB is another Jeff Sessions. She would recuse herself if the legal ruling contradicts her faith. That means death penalty cases and cases that contradict open borders. This pick needs to be a hard core conservative, not another Gorsuch.
This is what she wrote...

The Catholic Church's opposition to the death penalty places Catholic judges in a moral and legal bind. While these judges are obliged by oath, professional commitment, and the demands of citizenship to enforce the death penalty, they are also obliged to adhere to their church's teaching on moral matters. Although the legal system has a solution for this dilemma by allowing the recusal of judges whose convictions keep them from doing their job, Catholic judges will want to sit whenever possible without acting immorally. However, litigants and the general public are entitled to impartial justice, which may be something a judge who is heedful of ecclesiastical pronouncements cannot dispense. Therefore, the authors argue, we need to know whether judges are legally disqualified from hearing cases that their consciences would let them decide. While mere identification of a judge as Catholic is not sufficient reason for recusal under federal law, the authors suggest that the moral impossibility of enforcing capital punishment in such cases as sentencing, enforcing jury recommendations, and affirming are in fact reasons for not participating.
Amy Coney Barrett has CLEARLY stated that she would recuse herself from any case where the constitutional answer contradicts Catholic teaching, such as the death penalty or open borders.

Kyle Duncan is a much better choice.
