First, thanks to American Papist for the tip on this one.
Archbishop John Nienstedt of the Archdiocese of St Paul-Minneapolis denied Holy Communion to 25 "rainbow sash" types who were protesting the Church's stance on the sanctity of marriage. I urge you not only to read the full article, but to take the suggested action to voice support for the archbishop. Already one of his priests acted to undermine his authority by giving Communion afterwards to the protesters.
One can only imagine that the Archbishop will suffer additional fallout, and I regret pointing out that some of the opposition will come from some of his brother bishops who should know better.
