On one level, this week's GetReligion "Crossroads" podcast is about young Catholics, Confession and campus ministry, using my Universal Syndicate column from this past week as a starting point.

But "campus ministry," narrowly defined, is not what this podcast is about.

What host Todd Wilken and I ended up discussing (click here to tune that in) was a much broader topic. The key is that my column grew out of a very specific statistic that I saw in a blog post by Marcel LeJeune, who is assistant director of the massive campus ministry program at St. Mary's Catholic Center across from Texas A&M University. He wrote:

We know that of those that no longer identify as Catholic 79% do so by the age of 23 (Sherry Weddell, Forming Intentional Disciples, Page 33). So, young adults should be the focal point of our efforts and if we want to get even more narrow, then the best way to influence young people is to start with the most influential ones in their age group, the leaders. Most who end up becoming influential leaders will go to college. Finally, since 90% of Catholic college students go to non-Catholic schools, we MUST focus our energies on continued growth and dynamic evangelization in campus ministries at non-Catholic schools (mostly public).
