there is at least one past thread on this program, possibly in Liturgy or Family Life. The concept as far as it goes, catechizing the entire parish is sound, the framework of this program is sound, but like all these programs, the implementation makes all the difference. Who is running it, who is teaching it, what resources will be used, who will be invited, who will actually attend. How will sacramental preparation be handled, since GOF does not address it.
Get involved in the planning and implementation. Homeschoolers should love it in theory, because it places a lot of stress on the family taking the lesson home and expanding it.
A comparable family-centered program from Liguori is FIRE.
the difference between GOF or inter-generational catechesis, and CCD is that the same content is presented but in a different order and format. In a traditional program the sequence is usually creation, God, the Trinity, prayer, story of the fall and salvation in 1st grade
2nd grade prayers, penance, Eucharist
3rd grade, the Mass and the elements of the Catholic Church and creed
4th Grade, commandments & beatitudes
5th grade expanded teaching on the sacraments
6th Grade, OT and salvation history
7th grade NT and life of Christ
8th Grade Church History and Catholic Identity.
Saints, prayer and spirituality and Catholic practice are incorporated in the various age levels.
In an inter-generational program everyone receives the same content in any given year, in age-specific presentations, then comes together as a group to do process activities to reinforce the lesson. A typical plan is
year 1 - liturgical year and communion of saints
year 2 - moral life in Christ
year 3 - sacraments and liturgy
year 4 - OT
year 5 - NT
year 6 - the Creed.
so if a person attends for 6 years he gets all the content, but not in the traditional order.
there are also programs which are lectionary-based, the theory being that if you cover the 3 year lectionary cycle you will automatically cover all the doctrine. this would work of classes met weekly for 3 years, but in practice they usually meet once a month for half the year, leaving out out course a huge chunk of the lectionary.
sacramental preparation is usually handles separately with parent/candidate meetings, at-home study resources given to parents, or both.
problems: in a family centered program, only intact functional committed families are likely to participate, and to do the at-home activities suggested. other kids may be left out, those who attend Mass only occassionally will not be reached or involved. Parents not prepared to teach a lot at home will be left floundering.
What is supposed to be inter-generational and to involve the entire parish, actually seems uninviting and exclusionary if it is perceived as a family-only activity, or only for families with young children. Teens, singles, young adults, childless couples and retirees, while invited in theory often feel excluded by the way programs are run and presented and by the choice of resources used, format of meetings etc.
