The London and Stratford family catechism each began with three families, meeting at their homes on a regular basis for family rosary, snack, and a time of catechesis. These catechisms operated under seven guiding principles.
Over the years, additional families came to learn about the Family Catechisms through friendship and personal invite. Many wonderful initiatives (camps, conferences, clubs) have sprung up from these gatherings: the Holy Spirit is welcomed and active in this sort of organic group and it is amazing to see His work!
Seven Guiding Principles
Complete adherence to the teachings of the Magisterium of the Roman Catholic Church and the Pope.
Acceptance of the right and duty of parents to be the primary educators of their children.
This formational enterprise is a lay endeavor - not clergy - in order to demonstrate to the pupils their parents' faith.
Instruction will not criticize clergy. It should provide clear teaching in a positive manner of the Roman Catholic Church.
Parents as well as their children are to take part in this endeavor either as instructors or as participants in a parents' formation class.
The framework of the teaching enterprise is a community effort. As such, a fraternal bond and social interaction between families is to be fostered.
There is a joyful duty of apostolate for individuals and the group to follow the Holy Father's call to evangelize.
