I’ve seen all the popes since Pius XII. Each one was the right man for his time, even if it did not seem so at the time.
We had John Paul I for only a little more than a month. I don’t know what the cardinal electors expected him to accomplish. JP II took his name out of respect and memory of him, and that was a big tribute, if nothing else. That name was a combination of all three of his predecessors.
I think JPII and BXVI did a lot, but they had the priest sex scandal in their terms of office. Vatican II put the emphasis on the local bishops to govern the church, but there seems to have been failures up and down the line, things that should never have happened.
There is suspected to be a large homosexual lobby in the clergy right now. this is very controversial. A couple active priests have come out of the closet in the last couple of months.
None of the recent popes have come to terms with homosexuality directly head on. Watching them grapple with this crisis is like watching a bug trapped in a bottle. But, a lot of popes have been trapped by past crises. None of them has yet solved the schism with the Orthodox Church or the Protestant heresy of 500 years standing.
