JPII asked people to think about and even give him ideas on new ways to think about and exercise the Petrine ministry.
I don’t expect my idea to come to fruition ever, but I think it’s a good idea anyway
My idea is that all Christians would accept him as chief pastor. But no belief would be required for membership besides accepting him as chief pastor and a spirit of unity.
Then the traditional Catholic part of the new church would function just as it did always. Women wouild not be ordained, people not adhereing to Real Presence would not receive Communion, etc. And the pope would be recognized as chief pastor BUT the pope would STILL issue edicts just for these Catholics – so the pope would relate to the traditional Catholic Church just as before.
And the Anglican part of the new church would function a little differently. It would do as it does now except that the pope would be accepted as the head of the church instead of the Queen. Pastoral decisions of the pope would accomodate Anglican practice and views or if pastoral decisions would involve formal cooperation in evil (ex. appointing a woman as a bishop), then the pope could just let parts of the church be semi-autonomous.
And the Orthodox Churches would be in the same relationship to the pope as before the schism as they understand it. So they would view the pope of Rome as first among equals and the pope would respect that view. The only change would be that the Orthodox would have a practical acknowledgement of the pope in that special role of honor and apostolic authority and the pope could intervene when there is a dispute as the first among equals. Basically it would be exactly what the Orthodox want in their dialogue with Rome. Only difference is that the Anglicans would be given what they want too. The church would be a diverse organic unity with some parts (ex. Catholic and Orthodox) united in ways that other parts (ex. Catholic and Anglican) are not. IOW, there would be a lowest common denominator (acceptable to Protestants too), of pope as chief pastor and a spirit of unity. But there would be sub-ecclessial communities and communities of communities that have higher common denominators within the Big Tent. So in the Big Tent, there’s MidSize Tents that are in it and within the MidSize maybe some Little Tents too.
In a nut shell, everything in terms of beliefs would stay the same but structurally there would be greater unity and spiritually there would be a greater cohesion amongst all Christians.
