Jeff Jacoby uses Cardinal Sean O'Malley's address to Boston's Jewish community to write about improved relations between Catholics and Jews in America. Jacoby is right about improved relations over the last half century or so, but he is wrong in tracing it to a Vatican pronouncement in 1965. The real origins came about twenty years earlier.
I'm not a disinterested party in the discussion, but if you are interested, order and read this. Or wait around a while, there might be a book someday.
