I think sometimes we stand so close to an issue that our view becomes distorted - sort of the “forest for the trees”, if you will.
Most of the chaos in the liturgy (and for that matter, elsewhere in the Faith) started in the 1970’s and seemd to peak somethere in the late 1980’s - early 1990’s, if one was to step back and look at matters overall. If one is right in the middle of everything, it is easy to lose sight of changes, particularly when they are gradual and when they are over a much larger area (as in, for example, the US as opposed to your own diocese, or your diocese as opposed to your parish - of for that matter, the world Church as opposed to the US). John Paul 2 started the process of cleaning up many of the problems; Benedict 16 was forthright in saying that we need to look at Vatican 2 in light of the history of the Church and dogma, and many do not see that things have been moving away from the sillines, sometimes outright stupidity, and anchorless experimentation (whether liturgical, or in moral or dogmatic theology) of the past through the leadership both Popes have given us.
There are always going to be people who “don’t get it”. That has been going on for 2000 years or so, and going into a rigid “nothing can change” mode is not going to impact that one way or another.
One of the biggest problems laity have had in the last 40+ years has been the lack of adequate catechesis. What the Pope has done is just that - catechesis; read what Brother JR has posted.
For those poor souls who simply cannot absorb any instruction, there is not much that can be done. That however, is not a reason to stop instructing those who can learn, and in learning, can grow in their faith.
Far too many people have become hide-bound in their views of many rubrics, presuming that whatever is the first appearance of the meaning of the rubric, is the only meaning of the rubric. As in, many have been so caught up in, for example, the possible meaning of the 12 to be washed, that they missed the other points, particulalry service. On occasion, we need to have our preconceived notions challenged as they are limiting our fuller understanding of what Christ wants to teach us.
I suspect this Pope will have much to teach us; but we can learn only if we do not react in fear, do not have a knee-jerk response to the lesson, and quitely listen.
