Two snippets I'll highlight but it is a very moving article and you should read the whole thing here
The University of Notre Dame has been reprimanded by many for what seems to be a myopic decision to invite president Barack Obama—44th president and often staunchly opposed to the Church’s political positions—to give the commencement address at graduation and receive an honorary degree. The invitation has sparked outrage from many students and alumni, the former writing a petition protesting the president’s visit, and the latter withholding donations from the school. None of this, however, seems to me to be the fundamental problem, and I doubt whether these ancillary issues can be viewed correctly until the essential problem is addressed. This essential problem is that Christianity, to many people—including Christians—is nothing more than a moralistic, political ideology.
I haven’t mentioned much about Obama, because I think the issue his visit to Notre Dame has raised is ultimately: “What is Christianity? What about it is so worth defending?” This question remains unanswered unless we arrive to a true recognition of Christ, on the cross, giving us everything. In a sense, this is all that is asked of us. What upset me so much about the whole issue is how devoid of a recognition Christ’s presence the whole of popular reaction has been. If the essence of Christianity is power, as it is being portrayed both by the media and by those utterly outraged at the invitation, then I am not interested in being a Christian. I am interested in what made Zaccheus a protagonist; I am interested in the man who is able to call me down from the tree.
