As usual Orson Scott Card says something better than I could ever hope in his World Watch column Why I Miss Karol Wojtyla:

John Paul II, more than any other Pope, united, in feeling if not in fact, Christians who take the divine Redeemer seriously. That’s the “ecumenical movement” that means something, in my opinion.

Even though I am not a Mormon or a Catholic, I feel the greatest kindred spirit with those Christians whose faith demands (quoting Orson Scott Card’s column again)

…some real and rational degree of sacrifice, obedience, and adherence to faith…

so to Karol Wojtyla and Orson Scott Card I can only follow with an simple Amen.
