I think - speaking for my tradition, but I suspect it may be true to some degree in yours too - we have in recent decades talked a lot about how everyone has gifts and a part to play, how the mission of the church belongs to all its members, and so on, and on one level we believe it; but on another level, we deep down really believe much of the work of the church belongs to the "experts."
So, for example, I'll have someone who's doing a very good job visiting a housebound person, get upset because I haven't been to visit said housebound person. Why? I'm not bringing anything the lay person isn't; but somehow it's not as good if it's not the priest. Now that's nonsense, but it's really deeply culturally embedded.
That's just one example, but it's a pattern that repeats over a lot of things...
