The Christian family
The Christian family is a communion of persons, a sign and image of the communion of the Father and the Son in the Holy Spirit. In the procreation and education of children it reflects the Father's work of creation. It is called to partake of the prayer and sacrifice of Christ. Daily prayer and the reading of the Word of God strengthen it in charity. The Christian family has an evangelizing and missionary task.
