Archbishop Chaput gave a talk at Notre Dame on Catholics in the political square, according to LifeSite News:
There is unity among the bishops about abortion always being wrong, and that you can’t be a Catholic and be in favor of abortion - the bishops all agree to that - but there’s just an inability among the bishops together to speak clearly on this matter and even to say that if you’re Catholic and you’re pro-choice, you can’t receive holy Communion,” Archbishop Chaput said.
Chaput acknowledged he is only in favor of refusing Communion provided private notice is given to the individual ahead of time.
But Catholics who support legal abortion, Chaput continued, must be told they cannot receive Communion and told they should never approach Holy Communion. Along with other bishops, Chaput said he has been attempting for some years to have the USCCB speak publicly on the matter.
