Trust me. Our diocese would NEVER recommend something that was not solidly Catholic.
I know that.

The problem comes when a diocese puts a list out like you posted and some DRE/CRE who is eager to economize goes looking for material on the web instead of going to the Catholic publisher directly. They might get the Protestant material instead of the Catholic adaptation.
Hmmm, I think 1ke and I are talking about different programs, and maybe Corki and I are talking about the same one. If you google Crocodile Dock a whole bunch of VBS programs come up from different companies. Interesting–it is as if there’s some originator of the theme and then all these different publishing companies tailor them to their needs. Its all very confusing. Now I wonder where our parish ordered their stuff from…
These programs are sold through a variety of channels. The web sites that you find in a google seach are not usually for the company that developed the material but the retail sources. It’s like buying a book from Amazon or Ignatius Press. The book isn’t related to either one. I was also disappointed to find that the book companies are not always 100% truthful. At the conference I mentioned above, I got a sample of material for a program that, the rep assured me, was designed entirely for Catholics. It wasn’t; it was a popular Protestant VBS that was edited to include some Catholic content.
My problem with the Catholic adaptations was just that it was quite obvious that it was an “add on”. For example, in a small bubble in the leaders material, it might say to skip a portion on Scripture being the only guide. The portion was still in the material but there was a “Catholic” footnote directing the leader to skip it. The Catholic activities were not even included in the time line. If your volunteers were not thoroughly prepared or if the parish could not invest in a leaders guide for each volunteer, you would never know.
But again, even the Protestant versions are not likely to contain anything offensive to Catholics. The goal of VBS in Protestant churches is to be an outreach/evangelization tool while for Catholics, I think we see VBS as more of an summer extension of CCE/CCD.
BTW, Growing With the Saints is soldly Catholic by design, not adapted. I believe one of the developers posts here at CAF - or at least did last year at VBS time. K4J Summer Blast is another program that is designed to be Catholic from the ground up. It’s too late for this summer but might be useful to know when planning for next year.
