The phrase “domestic church” has been used to describe families since the beginning of Christianity. In his Letter to Families, Pope St. John Paul II explained, “The Fathers of the Church, in the Christian tradition, have spoken of the family as a ‘domestic church,’ a ‘little church.’”

The domestic church is believing that how you live your faith in your councils, families, parishes and community has a ripple effect that changes the world.

It is the council, the family and the parish that knows that everything they do must be based in surrendering prayer.

It describes the imperfect family and council who deliberately chooses to live contrary to what seems like a Godless world and says, “In our home, council and parish, we choose to live our faith.”

It is the family and council who prays together, goes to Mass weekly, frequents the Sacrament of Confession and (because they realize they are powerless without God), deliberately avoids that which pollutes their minds and hearts.

It is the imperfect, humble and joy-filled family and council that rarely preaches the faith because they are too busy living it.
