Again, papal infallability is not an issue here because JPII has not refined any church doctine (that I know about). However, perhaps because of the post-Vatican II collapse in catechesis, most Catholics don't understand the doctrine of church, and therefore papal, infallability.
The pope is NOT and was NEVER proclaimed to be infallable in matters of governance, only in his definition of doctrine acting as supreme leader of the church.
Since Vatican II the Catholic Church has been crumbling. It has joined the decaying hulks of the Episcopalian, Presbyterian, and Methodist Churches. Christianity in general is in bad shape. Its unfortunate at this time as it is facing a serious threat from both secular humanism on one hand and Islam on the other.
