The question, then, is, "Do these events do good in the world?"
Does the Al Smith Dinner do good? As I understand it, the ostensible point is the cultivation of rich benefactors for good works. However, to what extent do these potential good works really occur, and (on the other hand) to what extent does the scandal of displays of bonhomie with Death Eaters discourage the faith and good works of others?
Again, does the St. Patrick's Day parade do good in the world? What are the costs vs. the benefits, both in monetary terms to the city, and in pleasant-socialization vs. drunkenness and other harms? On the specific issue of homosexual groups' participation, does the celebration of homosexuality - an objectively dangerous lifestyle, regardless of moral concerns - do good in the world?
When anyone like ND or the diocese of NY invites the hero of Benghazi to dinner they are honoring a person who believes it is ok to let a baby born after a “failed abortion” attempt to die of neglect. And sitting and laughing with him. What could be so funny or important to ignore those beliefs?
This is who some in the church would and have honored.
I guess of Pelousy and Kerry can receive communion then anything is possible.
