Last week at the HLI World Prayer Congress in Rome, Archbishop Burke stated plainly that (and I quote verbatum) “When a person has publicly espoused and cooperated in gravely sinful acts, leading many into confusion and error about fundamental questions of respect for human life and the integrity of marriage and the family, his repentance of such actions must also be public.”
I urge you to read the full article at Lifesite News, which also contains links to the full address and to the video. Archbishop Burke has spoken on this subject before, and has also been quite plain in proclaiming truth.
I urge all prelates in the United States, and the world, to take seriously to obey Canon 915 in dealing with those politicians who remain recalcitrant. That's an obligation, not a "pastoral option". It's not a matter of "turning Holy Communion into a weapon". It's a matter of preserving the Blessed Sacrament from blasphemy and preventing the politician from committing yet another mortal sin, that of sacrilegious Holy Communion. I also raise the question of whether or not the knowing distribution of Holy Communion to such a person constitutes formal and material cooperation with the blasphemy - a serious matter in and of itself, I'd think.
