Although I am not a Catholic, I was among the many outside the Church who found Pope John to be an inspirational figure during his tragically short Vatican tenure in the early 1960's at the height of the Cold War.
Chances are good that we will soon be acknowledging JPII as "Saint," but none of this will make much difference in how Catholics live their lives everyday. There is a more important reason, I think, to remember JPII.
In enshrining the Church's divided World War II loyalties by canonizing the ambivalent pope at the time, the Church would be announcing to the world what it's made of. Pius should be neither demonized nor sanctified.
