Having read the article, I am not convinced that all issues were resolved by it.
It may well be that a bishop in a different diocese than, say, Kerry resides, could tell Kerry not to present himself for Communion at any church in his diocese; and likewise, it may be that a bishop could tellthe priests in the diocese not to give Communion to Kerry should he show up.
However, the issue goes more to the parish priest in any given parish. If the priest does not know the status of an individual who shows up (say, the governor of Oregon, a Catholic who supports abortion), or does not particularly know what position the governor holds but might think that he is a candidate for exclusion, then I would think that before refusing the Governor, the priest would have to speak with the Governor.
In other words, Burke’s letter seems more directed to the pastor of the parish the individual resides in that to the sometimes hapless pastor of the parish the indvidual happens to go to Mass at next week while traveling.
And as to an EMHC, the issue is to be decided by the pastor, not on the EMHC’s call.
All of which gets back to Burke’s article; I wonder how many people would actually recognize Nancy Pelosi if she showed up, and if they did, how many would actually know what her postion was on abortion (or whatever specific issue would result in exclusion).
I know her position, but unless she were making a photo-op Mass, I wouldn’t know her from any other middle aged female who might be visiting the parish.
