Thanks for the question Sunstone.
John Paul II is an example to the whole world of genuine holiness and peace. From his earliest days working against the Nazi's in WWII, to the world shaping influence he used to liberate Poland from Soviet rule, I don't believe any other single person in the last 100 years has done more to promote peace and the dignity of the human person. Some say that his influence in Poland was the turning point to the end of the cold war... I am sure that there were several other important factors, but none can deny that his influence played a large part.
As faith is very important to me (as you know) JP II has succeeded in comprehensively restating the contours of the Catholic faith in the light of Vatican II and in relation to postconciliar developments in the Church and the world. With his keen interest in contemporary culture, philosophy, economics, and international affairs, he has been
able to give fresh relevance to the Catholic tradition.
His encyclical letter Ut unum sint in 1995 will be viewed as the blueprint for the Catholic Church in the area of ecumenical relationships for 100's of years. I also believe that he has moved the faith forward post Vatican II towards a true repair of the broken relationship we have with the Eastern Churches. For the first time in almost
1,000 years, the faith has a real chance to once again "breath with both lungs" in a large part due to the beauty and brilliance of his encyclical letter Orientale lumen (1995).
I also believe that his defense of the dignity of human life is the fullness of the message of peace. To defend the innocent is the basic theory of peace, and I don't think many have done more to open awareness to the holocaust of abortion in this country.
Peace,
Scott
