Aren't we lucky that we are so much more intelligent and knowledgeable than those gone before us. That we have this 'deeper' understanding of Christian history and the teachings of Jesus. I would, of course, hesitate to reprimand Our Lord for lumbering previous generations with relative ignoramuses such as the Fathers of the Church, Saints Augustine and Thomas Aquinas, Theresa of Avila among others.
Why couldn't Hans Küng, Charles Curran, Matthew Fox, Jacques Gaillot, Eugene Kennedy et al have been born several generations earlier when they could have teamed up with Luther, Melancthon, Calvin, Zwingli, Bucer and the rest. 
We would have had a comprehensive world religion today headed by the United Nations in New York rather than in the centre of the Old World.
