You know, I've wondered about this myself. I have always figured that it was due to the hand of God having protected him during those years.
Your post implies that there may have been some nefarious plot by the communists to enthrone John Paul as the Pope. Let's, for the sake of argument, say that this is true. God's ways are not our ways. It appears that God willed that this man be the Pope. He was duly elected by the College of Cardinals. No one has come forward seriously claiming to be the true pope. (Except for that poor, old, demented man in Montana.) And, after all, if it wasn't His will, God had the chance to be rid of him with the assination attempt quite a few years ago.
Do I agree with everything that the Pope says and does. No. Theologically, I'll leave that up to the Pope and the theologians to hash out. When I do question the Pope's theology, it is to understand what he is saying and not to look for imbedded heresy, as so many love to do. His prudential decisions and actions, yes, I question and have my own opinions. For instance, if I were Pope, I wouldn't kiss the Koran, or allow the ecumenical shindigs at Assisi. I would have quite a few Cardinals and Bishops looking for other employment. However, I'm not Pope, and until the time that God sees fit for me to be Pope, I will allow God to work His will through this Pope.
In the end, there are 2 things that we all can do. 1) Pray unceasingly for the Pope and the Church. 2) Trust in Jesus' promise to St. Peter that "the gates of Hell will not prevail."
You underestimate the power and presence of evil within the College of Cardinals. From John XXIII to present the college has been stacked to elect another Wojtyla or worst.
Our Heavenly Father isn't in the business of interfering in the 'free will' of those placed in the top leadership roles of His Church. Although they may have achieved their posts by deceit, once anointed, the when, where, what and how they act or fail to act covertly or overtly is their 'free will'. But rest assured there are no free passes to His Kingdom.
Every Roman Catholic has a duty to expose contamination within The One True Faith. Every 'Christian' made aware of the One True Faith, but decides to refuse conversion will likewise answer for their 'free will' decision. Conversion is essential to salvation, because God said so. There will not be an ACLU on judgment day to defend against the Will of God.
What we do or don't do in response to our awareness of evil within the walls of His Church falls once again into the realm of 'free will'. Rest assured The Blessed Trinity has an accounting of each of our failings to rise above vanity and defend The Faith. Our actions and our unwillingness to act according to His Will awaits our judgment.
Yesterday a Christian in Saudi Arabia chose to deny The Blessed Trinity in order to save his life. May God have mercy on his soul.
