As a member of a Diocesan Catholic Committee on Scouting, my number one desire is a way to identify Catholic families participating in non-Catholic units. We have a mandate and desire to offer our religious emblems and other ministries to them, yet we have no good way of communicating with those families. I hear very similar thoughts from the scouting committees of other church bodies. Probably the majority of Scouts (other than in LDS units) are generally not members of the chartering religion, and likewise the majority of the scouts of a given religion are in units of another faith or a civic organization. This makes religious emblems and other religious ministry through scouting much more difficult. (Has anyone else noticed that religious preference isn't on the medical forms anymore either?)
I would be perfectly happy to see some sort of more autonomous form of Catholic Scouting in the USA, but still formally in relationship (even if only as a licensee) with the BSA. Frankly, I think if BSA had been built on a federated model rather than constructed as a rigidly uniform national corporate/bureaucratic organization, many of the present issues and controversies could have been avoided. It still could take a federated path, though I think it unlikely.
I don't think there will ever be a global Catholic Scouting organization that reaches from the Vatican directly to the individual Scouts. (Plus the Vatican is often as poorly run as the glass tee-pee in Texas that oversees the BSA, old saying about the Vatican goes: technology should be updated every 75 years if it is needed or not.) However, I do sometimes think some form of international Catholic Scouting honor society, based on a chivalric model, could have some real potential. Imagine the selling power of an organization that had Papal Knighthoods as its top honors.
Another note, take all statements from the National Catholic Committee on Scouting with a bit of skepticism. The NCCS-BSA is specifically charged by the bishops with maintaining good relations with BSA. It doesn't really have the option, on its own, of terminating or significantly modifying the Church-BSA relationship. It can't even offer a clear rebuke or criticism, all it can offer is mild statements of disappointment. The NCCS doesn't even really have any clear policy making authority at all. Likewise, the members of the NCCS aren't really objective, most are very deeply embedded in the Scouting system, to a degree that may compromise the independence of the members (I say this with full awareness that I myself am not able to be fully objective on these questions, either).
I fear that the more liberal sorts of Catholic parishes will increasingly become the place of refuge of scout units booted out by churches that wash their hands of BSA, meanwhile I suspect more conservative Catholic parishes will convert their BSA units into some other form of youth ministry (alternate "Scout" programs, Columbian Squires, Knights of the Altar, young men's ministry, etc.).
Also, the "Troops of Saint George" (BSA persists in its heavy handed monopoly on "Scout") actually does exist. I signed up for their mailing list just to keep aware of what they are up to. Like the Federation of North American Explorers, I expect their growth path to be very gradual, but I think both the FNE and the Troops of Saint George are better fits for Catholic parishes than Trail Life USA. I just don't see a Catholic future in Trail Life from where I sit.
Now, the big question is, is there a Catholic future in BSA?
I am increasingly skeptical and cynical, but not yet convinced in either direction.
