Thanks for posting the video as it helps me understand another side of the mission.
I maintain that there is no monopoly on the mission. What works for some may not work for others. However the mission remains to bring the good news to people.
What is interesting to me at least after hearing Fr. Leo speak is what he believes is the proper response to a flock that is leaving the church at an alarming rate. He cites between 70-85% of confirmed Catholics leave the faith once they become adults. This is a different metric than newly baptized which are typically children. I would tend to agree with those numbers if I look at just my own family. For us it's more like 50% that grow up and stop attending church on a weekly basis. My adult kids are in their 20s-30s. Unless it's Ash Wednesday, Christmas, or Easter they are not regulars. We had a full pew this past Christmas as they have honored mom and dad to attend mass at the school they attended for 10+ years as children. It is actually something they look forward to thankfully.
That said, I would have to agree more with what Vatican II has identified as the prime focus for the "Church in the World" through its Pastoral Constitution Gaudium et Spes, a landmark document calling for the Church to engage in dialogue with modern society, interpret "signs of the times," and apply Christian faith to contemporary issues like human dignity, social justice, peace, and cultural development, shifting from an inward-looking stance to an outward-facing mission to serve humanity's joys and anxieties.
My kids attended a gothic cathedral, full of all the sacred art, vestments, music, and visuals one can imagine. They benefited from religious instruction both at school and at home. No doubt it had an effect on them as children and young adults. All but one is confirmed. All but one was active with the youth ministry attending retreats, DCYC youth days, and more.
If I am being honest, what stuck with them the most was our weekly interaction with the homeless that are all around the Cathedral in downtown Austin. They would give out of their own money and food to these people on their own. Even now, they care about the less fortunate and marginalized which we as parents tried to model charity those many years ago.
I believe that what draws some people into the church is different than what is needed to transform their hearts to keep them close to God.
