After-school Catholic religious education classes are the issue, not attendance at a Catholic school.
oh cripes I totally misread that - you'd think I'd know better after attending Catholic schools for 10 years!!! ha! But you know what's odd, I knew quite a few kids who had split parents, one Catholic, one protestant, and they didn't attend Mass, but they sent their kids to CCD classes. Interesting that they're wanting to handle it this way.
