The church has often spoken paradoxically about growth in Christian faith: to grow means to stay at the beginning. The great Reformer Martin Luther exemplified this. “Although I’m indeed an old doctor,” he said, “I never move on from the childish doctrine of the Ten Commandments and the Apostles’ Creed and the Lord’s Prayer. I still daily learn and pray them with my little Hans and my little Lena.” He had just as much to learn about the Lord as his children. The ancient church was founded on basic biblical teachings and practices like the Ten Commandments, baptism, the Apostles’ Creed, the Lord’s Supper, the Lord’s Prayer, and corporate worship. These basics of the Christian life have sustained and nurtured every generation of the faithful—from the apostles to today. They apply equally to old and young, men and women, pastors and church members. “In Christ Jesus you are all sons of God through faith” (Gal 3:26). We need the wisdom of the communion of saints. They broaden our perspective beyond our current culture and time. “Every age has its own outlook,” C. S. Lewis wrote. “It is specially good at seeing certain truths and specially liable to make certain mistakes.” By focusing on what’s current, we rob ourselves of the insights and questions of those who have gone before us. On the other hand, by reading our forebears in faith, we engage ideas that otherwise might never occur to us. The books in the Christian Essentials series open up the meaning of the foundations of our faith. These basics are unfolded afresh for today in conversation with the great tradition—grounded in and strengthened by Scripture—for the continuing growth of all the children of God. Hear, O Israel: The Lord our God, the Lord is one. You shall love the Lord your God with all your heart and with all your soul and with all your might. And these words that I command you today shall be on your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise. You shall bind them as a sign on your hand, and they shall be as frontlets between your eyes. You shall write them on the doorposts of your house and on your gates. (Deuteronomy 6:4–9) 

THE APOSTLES’ CREED
 I BELIEVE IN GOD THE FATHER ALMIGHTY,

maker of heaven and earth,

AND IN JESUS CHRIST, GOD’S ONLY SON, OUR LORD:

who was conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, died, and was buried. He descended into hell. On the third day he rose again from the dead. He ascended into heaven and is seated at the right hand of the Father, and he will come again to judge the living and the dead.

I BELIEVE IN THE HOLY SPIRIT,

the holy catholic church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting. AMEN.
