Pope Benedict, at age 81, was remarkable in the USA. Such energy and clarity of mind. Such a fluent speaker. And that mass in Yankee Stadium was unsurpassed in the way it was organized and orchestrated.
However, two problems.
(1) Pope Benedict made two major gaffes some months ago. One was to quote a medieval Catholic who declared that Islam was evil. Not smart to do, even if the Pope thought it. Even more detrimental in the USA were his comments last summer to the effect that Protestant churches were not really churches bu 'ecclesial entities' and that Protestant ministers did not properly conduct communion. Again, even if he thought this it casts doubt on his judgment to say this aloud. It certainly disgusted many of my Protestant friends.
(2) Pope Benedict's emphasis at Yankee Stadium was on the authority of the church and the need for Catholics to obey their church. Sounds okay but Catholics have been rebelling against church authority and do not want to be told like children that they have to believe and do what Mother Church says. This is why so many in, say, Catholic Quebec and Catholic Ireland have become alienated. They have come to resent any attempt of the church to make them conform. They have to be won over and will not respond to appeals to church authority. They can be attracted by a church that is open to new ideas and practices, a church that is not anchored in the ancient and medieval past and refuses to budge.
