A major change in the way people should think was also recognized in the Council. More of an emphasis was placed on individual or personal conscious. The Church believes that once one know the doctrines and the teachings of the church they will present the material in a way that is consistent with church teachings but will do so with the individuals own conscious. This acceptance of personal conscious accounts for the differences in presentation of material by priests. It allows for conservative and liberal priests.
Some clergy put more personal conscious into their teachings than others.
Vatican II is recognized in varying degrees throughout the Catholic community. For instance, most of the priests in the Eastern United States haven't recognized many of the changes from Vatican. They are generally more conservative and resistant, change may not occur in their parishes. Catholics in the Western U.S. attending mass in an Eastern U.S. Church probably wouldn't recognize most of what goes on in an eastern mass. Eastern U.S. has more European influence and is watched much closer by Rome.
