Students of church history know that some views that are mocked and condemned are eventually embraced as church teaching. Such was the case with the Franciscan Duns Scotus, who defended the idea of the Immaculate Conception before it was accepted by the universal church. One sticking point was whether Mary could be conceived without original sin by virtue of the merits of Christ's passion, death and resurrection which had not yet happened in time. The resolution was to insist that Mary, like all of us humans, was redeemed by Christ's merits, but outside of earthly time.
Both John Paul II and Benedict XVI have also recently embraced another opinion of Duns Scotus that Jesus's Incarnation had been a plan of God all along, not only after Adam and Eve's sinful disobedience led to "the fall." This to fully sanctify human nature and become one with us.
Sometimes, with humility and trust in God, you have to be willing to be wrong for a very long time!
