What can be done about this?
Probably nothing. We’re talking about reversing a seventy-year-old-and-still-going-strong civilization-wide trend that affects not only Catholics, nor only Christians, but people of all religions, not only in the US, but in every country outside of sub-Saharan Africa. When people have a real free choice to join the religion of their choice or to change religions or leave religion altogether, they more and more decide to leave religion altogether, or to become “culturally”, but not practicing religious.
The coercive methods available to religious groups in the past are no longer in force. There is no longer any stigma in not being associated religious among younger people today. In fact, the opposite is quickly becoming true.
Add to that that Catholicism, Christianity and “Religion” in general are broadly associated by young people with social views that young people not only do not agree with, but find morally repugnant, like misogyny, homophobia and xenophobia, and are often politically allied with right-wing political parties and organizations that young people consider “the enemy”, and it’s little wonder that there is little appetite for religion among younger people.
Then add a long and ongoing history of hypocrisy and incessant scandals related to sex and finance, fostered by a culture of cronyism and secrecy that abhors the light of day and lacks anything resembling transparency and accountability and possesses a strong reflex to blame anyone else for its own failings, from the “mainstream media” to “secular culture” to “TEH GAYZ”, and you have exactly the type of organization that young people are out to destroy rather than to join.
Unless Church leaders are able to view the Church with the same untinted glasses that young people of today do, and honestly own up to it, warts and all, they will never be able to correct their failings. They will continue to scare off more young people than they tiny few that they attract, and the Catholic Church, like just about any other religious body in the world outside of sub-Sarahan Africa, will become a ever-shrinking niche group devoid of cultural significance.
Call me a pessimist, but I don’t see much in the way of leadership, fortitude and intellectually honesty among the leaders of our Church. Most are hoping for a quick and easy magical solution, like pixie dust you can sprinkle on a congregation and make it swell with young people. Whatever solution there might be, if there is one at all, is going to be a bear to implement.
Sorry to rain on your parade, but if you are going to start anywhere, you’re going to have to start with a honest acceptance of the brutal facts, and admit that the damage has been almost entirely self-inflicted. Only from that perspective are you going to be able to come up with a solution.
I sincerely wish you luck with that. My generation failed abjectly. Maybe yours will succeed. There’s always hope.
