He's only half right here. He, like many of the "American Catholics" he seems to be talking about, has the irksome quality of treating the Church as if She is a great universal political party for the world.
"Since our own dreams are always more limited than those ... [other people throughout the world]" Bleech! What about God?
A good poet (of which I'm not) might finish it off something like this:
"Since our own dreams are always more limited than the Grace God wishes to bathe us in to participate in performing His Will".
True ... but ... he touches on some excellent points that impact and get to the bottom of the Catholic Church's approach to ecumenism. That, more than anything else in this article, is what captured my interest.
To cite an example, on Thursday morning, the governor of NY, visiting China for trade negotiations, established a live link with the US press. In response to one reporter's question, he commented that though NY and many other states, have lost jobs to the Chinese marketplace, we must face reality. He cited Chinese history where they tried to protect themselves by building the Great Wall. It didn't work then and it won't work now.
The same is true for the Catholic Church. It must reach out to find and build upon common ground.
