San Jose, CA is not my diocese, but I take interest in it because I used to live there. This month the diocese released its 2023 Pastoral Plan that will guide operations for at least the next five years. Several months ago, the diocese hired a lay C-suite level executive in a newly created directorship to oversee the plan's implementation. Link to the document here:

On page 6, the diocese states the following catastrophic declines in Catholic practice:

- While the general population in the diocese has increased by 5.8%, Mass attendance has decreased by 39.8% and children's faith formation enrollment has decreased by 40% over the past ten years.

A 40% drop in Catholic affiliation and practice is alarming, possibly a Blockbuster Video death-spiral level decline, but also consistent with what has occurred in other urbanized, secular regions of the United States.

Of particular interest to people here might be what the diocese proposes regarding worship. That section starts on page 13. On page 15 is this objective about liturgical music:

Objective 4: Lift spirits with engaging, liturgically appropriate music

In our parishes and schools, the People of God can expect:
• Improved quality of liturgical music based on the unique cultural preferences of each parish and school community.
• Highly trained and spiritually formed liturgical music leaders, cantors, and musicians.

The diocese will support parishes and schools by:
• Appointing a diocesan leader for music ministry.
• Updating diocesan music ministry standards, policies, procedures, roles, responsibilities, etc., based on best practices from within and beyond our diocese.
• Developing and supporting music ministry formation and training programs for liturgical music leaders.

Does anyone agree with me that this objective is flawed from its inception and at its core? "Lifting spirits with engaging music" is what has been attempted for the past forty years or more. That hasn't worked. Whether such music has contributed to the exodus of Catholics from attending Mass is debatable; I believe it has because it has made Mass seem like a secular activity with "Jesus sprinkles" that can easily be regarded as optional or uncompelling. Basing music choices on "the unique cultural preferences of each parish and school" is not a criterion for liturgical music that appears anywhere in the Church's documents or rubrics about liturgical music.

Regarding the goal of having "highly trained and spiritually formed liturgical music leaders, cantors and musicians," good luck with that when the document also admits that there are "financial challenges, staffing and compensation challenges, and rising costs of living" in most parishes. (pages 6-7)

I think implementing Vatican II's liturgical reforms and the new Missal authentically is going to take about 200 years. I also expect further catastrophic declines in Catholic affiliation and practice in the United States over the next 30 years. Many dioceses will contract further, and there will be even more parish mergers and consolidations.
