"The family is the heart of the New Evangelization, since it is where the faith is first encountered, passed down, lived, and sustained." (USCCB, Marriage and Family: Home of the New Evangelization)
As stated on the USCCB website, evangelization first takes place in the family. Parents, “by word and example, are the first heralds of the faith with regard to their children” (Lumen Gentium, no. 11). Also called the “domestic church,” the family is a small version of the Church. The family receives its life from the Church and in turn mirrors the life of the larger Church. In the family, children first learn about God, love, and the Church. Mothers and fathers are indispensable in sharing the faith with their children. When parents practice and live their Catholic faith, children receive a sure foundation to assist them in difficult life choices. As parents and families learn and live their faith, they grow in confidence in the Gospel of Jesus Christ and his Church and are nourished by the sacraments and desire to share. The family has an invaluable role in passing on the faith in a joyful and bold manner. Children will learn that they are members of the Body of Christ and have a valuable role in the Church.
Evangelization in the family is not a complicated task. It can be age appropriate and begin with simply teaching children the Sign of the Cross, the Our Father, Hail Mary, and Glory Be. As they mature, reading from Scripture and the lives of the saints can touch their hearts and imaginations. Parents teach children to live the virtues (Gal 5:22-23) and love the Lord with their whole hearts (Mt 22: 27). When children see their parents committed to the Lord and his Church, they are much more likely to do so themselves. Families are uniquely qualified to invite their family members, friends, and neighbors to return to the Church or to consider becoming CatholicThe home is the first school of Christian life and “a school for human enrichment.” Here one learns endurance and the joy of work, fraternal love, generous — even repeated — forgiveness, and above all divine worship in prayer and the offering of one’s life."
