another name for it is inter-generational catechesis. in theory it is a good thing, providing ongoing teaching for all ages and involving all age groups in one lesson on one topic, with presentations and activities geared age appropriated. It is usually based on the lectionary and follows the liturgical year, rather than the more traditional systematic presentation of doctrine.
In practice, in the parishes I know of that use one of several programs out there, it is families with young children, meeting once a month for a 2 hour presentation, very fluffy, of a topic with games, songs, crafts etc to “reinforce” the lesson (such as it is). there still has to be a first communion program since sacramental preparation is not covered. If a family attended faithfully for 6 years they would get a general overview of the same topics covered in 6 years of conventional CCD.
Problems: other than families, almost nobody else participates. Teens HATE it unless they have roles as teachers aides and it does nothing to meet their unique needs. There still has to be parallel RCIA and sacramental prep programs. It is fine for involved families, but leaves no room and makes no provision for kids who are “dropped off” at conventional CCD and have no one in the family who will become involved in the family program. some programs are intended for small groups of families in neighborhoods to meet in homes, but with the recent stricter guidelines for oversight of any programs involving children, this is not really possible or advisible.
Any adults interested in serious adult education or bible study will be bored stiff and turned off by the Catholic lite approach of an intergenerational program.
we do have a family program, it is intended for families where both children and adults need sacraments, meets on Sunday at the same time as RCIA, and adults, teens, and children have their own catechists for their age level, and come together for the scripture and breaking open the Word portion and some seasonal activities. It is also offered as an alternative for those who cannot attend regular CCD during the week, but parents must participate, it is not drop-off. This removes their excuses for not coming to CCD.
Our version of whole community catechesis is to send home (after an intro and explanation of how to use it) CTL’s Family page in English/Spanish with Sunday readings, reflection and suggested activities for sharing and implementing the gospel message in daily life. This sheet is used in all CCD and RCIA classes, and goes home to all families, and is available with bulletin as well to non-CCD households. We also do a brief faith sharing with the Sunday Gospel before each parish meeting and gathering, to get people in the groove with the concept. Some small faith communities have also started using it, and some of the neighborhood prayer groups.
