Sunday-School
Short answer: Deuteronomy 6:6-9 answers the question of who teaches the faith: the words of God are to be on the heart, taught diligently to children, and spoken of at home, on the road, at bedtime, and at rising. Sunday school is not commanded in this passage, but the pattern it describes gives the classroom its proper place. A weekly class can reinforce, explain, and extend what parents begin, and it gives children a community of believers beyond their own family. What Scripture does not support is outsourcing the faith to a program. The class helps; the home remains the primary school. Parents who teach, and teachers who come alongside them, both serve the same command. Where faithful Christians differ is in how formal that partnership should look, not in whether it should exist.
What Deuteronomy 6:6-9 actually commands
The passage begins with the heart, not the schedule: Deuteronomy 6:6 says, "These words, which I command you today, shall be on your heart". Before anything is taught to a child, the words must live in the teacher. That order matters for Sunday school because a lesson prepared from a curriculum but not from a heart shaped by Scripture will produce information without formation. The teacher's own life is the first classroom.
The command then moves outward to the next generation. Israel was to teach these words diligently to their children, speaking of them when sitting in the house, when walking by the way, when lying down, and when rising up. The verbs describe ordinary, repeated, daily conversation, not a single weekly event. The setting is the whole of life, and the teachers named are the adults who share that life with the child.
Finally, the words were to be bound on the hand, worn between the eyes, written on doorposts and gates. Israel took these instructions literally in various ways, but the underlying point is that God's truth should mark the spaces where a family lives and moves. A house that visibly belongs to God makes teaching natural rather than awkward. Sunday school can echo that environment, but it cannot create it from the outside.
Why the home has the first claim on teaching
The home has the first claim because it has the most time. A Sunday school teacher sees a child for roughly one hour a week. A parent sees that same child for dozens of hours, in moods and moments no classroom can reproduce. Deuteronomy 6:6-9 assumes this ordinary time is the raw material of discipleship. The parent who answers a question at bedtime, prays before a meal, or admits a fault and asks forgiveness is teaching in the exact way the passage describes.
Time is not the only factor. The home also has the deepest authority and affection. Children learn what they see repeated. A faith that is only discussed in a classroom and never practiced at the dinner table becomes a subject rather than a life. Paul reminded Timothy that he had known the sacred writings from childhood, and he connected that knowledge to the people from whom Timothy learned it. Teaching is always personal before it is institutional.
This does not mean every parent feels adequate. Many do not. Moses himself objected that he was slow of speech when God sent him. The command in Deuteronomy is not a demand for expert teachers; it is a call for faithful ones. A parent who reads a passage aloud, asks what it means, and prays with a child is obeying this text, however imperfectly.
What Sunday school can do that the home cannot
Sunday school offers something the home cannot always supply: a wider community. A child who learns the faith only at home may come to think of it as a family quirk. A class gathered with other believers shows the child that the truth is held by many. Acts 2:42 describes the first church continuing steadfastly in the apostles’ teaching and fellowship, in the breaking of bread, and prayer. Teaching and fellowship belong together, and a class can join them.
A class can also provide structure and a teacher with preparation time. Some parents are new to the faith, some work long hours, some struggle to read well. A trained teacher who studies the passage during the week serves those families genuinely. The class can introduce a book of the Bible the family has not yet tackled, explain difficult words, and give children the vocabulary to ask better questions at home.
Finally, the class can reach children whose homes do not teach the faith at all. For a child whose parents are indifferent or absent, the Sunday school teacher may be the only adult speaking the words of God. In that case the classroom is not competing with the home; it is filling a gap the home has left open. The command to teach children is not limited to parents by blood.
Psalm 78 and the chain between generations
Psalm 78 begins with the same burden: the teaching spoken to the people is to be turned into words for the next generation. Psalm 78:1 says, "Hear my teaching, my people. Turn your ears to the words of my mouth." The psalm goes on to describe a pattern of telling, of not hiding the works of God from children, but declaring them to a generation to come. The concern runs backward and forward at once.
The psalm is honest about why the chain matters. Israel’s history records generations that forgot, rebelled, and repeated the failures of their ancestors. The psalmist is not merely recommending education; he is diagnosing a pattern of forgetting that produced disaster. A class that only entertains children while leaving them ignorant of God’s works has missed the psalm’s point entirely. The aim is remembrance that shapes obedience.
Notice that the psalm does not locate this teaching in a single institution. It calls the whole congregation to hear, then charges each generation to tell the next. Sunday school is one link in that chain, useful when it serves the telling, harmful when it replaces it. The question to ask of any program is whether it makes the next generation more likely to remember and obey, or merely more likely to attend.
Matthew 28: making disciples, not just running classes
The risen Jesus commissioned his followers to make disciples of all nations, baptizing them and teaching them to observe all that he commanded, and he grounded that commission in his own authority and his presence to the end of the age. The word translated as teaching in that commission is broader than a lesson delivered; it includes the ongoing formation of obedience. A Sunday school class is one way to obey this commission, but the commission itself is given to the church as a whole, not to a classroom.
This matters for how we judge success. If a class produces children who can recite Bible stories but do not follow Christ, it has not made disciples. If a class produces children who follow Christ but cannot explain the gospel, it has been incomplete. The goal is whole persons who know the truth, love the Savior, and obey him. That goal is too large for a weekly hour and too important to leave with a single teacher.
The promise attached to the commission, that Jesus is with his people to the end of the age, is a comfort to anyone who teaches. The work does not depend on the teacher’s eloquence or on visible results. Christ is present in the gathering of even two or three who meet in his name, and he is at work in the slow, unglamorous business of teaching children to obey.
Colossians 3 and the whole congregation as teachers
Paul’s instruction in Colossians 3:16 widens the circle again: "Let the word of Christ dwell in you richly; in all wisdom teaching and admonishing one another with psalms, hymns, and spiritual songs, singing with grace in your heart to the Lord." The teaching here is mutual and shared by the whole assembly, not the responsibility of a select guild of educators. Sunday school is one organ within that body, not the body itself.
This has practical consequences. If the congregation sings, prays, and speaks the word together, children absorb far more than a weekly lesson provides. The songs they hear in worship, the prayers they hear spoken, and the conversations they witness between adults all teach. A child who hears a psalm sung in the assembly alongside a lesson on that psalm receives a double formation, and the two reinforce each other.
It also means Sunday school teachers should not work alone. When a teacher and the worshiping congregation are at cross purposes, the child receives mixed signals. When they agree, the child learns that the faith is one thing, held by one people, spoken in many settings. That unity is itself a form of teaching, and it may be more powerful than anything said from the front of a class.
Where the modern Sunday school model falls short
The Sunday school movement, as it developed over the past few centuries, has done real good: it has taught literacy, reached poor children, and given countless people their first knowledge of Scripture. But the model has weaknesses worth naming. When parents assume the class will handle spiritual formation, the primary command of Deuteronomy 6:6-9 goes unfulfilled. The classroom becomes a substitute rather than a supplement, and the family loses the habit of talking about God at home.
Another weakness is the pressure to entertain. When a class exists to keep children happy, the content can shrink to what is easy and pleasant. 2 Timothy 3:14-17 presents Scripture as profitable for teaching, reproof, correction, and instruction in righteousness, categories that include uncomfortable material. Children can handle the whole counsel of God, including judgment and repentance, when it is presented with care and hope. Watering it down underestimates them and disobeys the text.
A third weakness is isolation from the rest of the service. Where children are sent out for the sermon and never see adults worshipping, they learn that the gathered church is an adult thing. A healthier arrangement lets children participate in worship and receive instruction, so that both are seen as belonging together. Congregations will weigh the practical details differently, and faithful Christians differ here, but the principle is worth considering.
A workable partnership between home and class
A simple partnership works best. The class teaches a passage during the week’s gathering, and the family revisits the same passage at home. Parents do not need to prepare a lesson; they need only to read the text aloud and ask two questions. The repetition across settings is precisely what Deuteronomy 6:6-9 describes, where the words are spoken when sitting, walking, lying down, and rising.
Teachers can help by sending home the passage and one question the class discussed. A single sentence on a slip of paper is enough. If the teacher tells parents what was covered, parents can extend it naturally at dinner. 2 Timothy 3:14-17 assures us that Scripture itself is able to make a child wise for salvation, so the goal is not to produce clever lessons but to put the text in front of the family repeatedly.
Churches can also resist the temptation to build a program larger than their people can staff. A single class taught well, with parents engaged, will do more than several classes run on exhausted volunteers. The measure is not the number of rooms in use but whether children are coming to know the Lord and whether homes are becoming places where his words are spoken.
Biblical fidelity check
Deuteronomy 6:6-9 establishes that God’s words are to be on the heart, taught diligently to children, and spoken of in the ordinary settings of daily life. It does not establish Sunday school as an institution, does not prescribe a curriculum, and does not specify a classroom, an hour, or a teacher. The passage commands a practice, not a program. It also does not say that parents are the only permitted teachers, since the wider assembly is plainly involved in teaching elsewhere in Scripture.
A common misreading is that this passage makes Sunday school unnecessary, as though serious families must teach everything themselves. That overcorrects. The passage commands the home to teach; it does not forbid the church to help. The opposite misreading is equally wrong: to treat the class as the place where children get their religion, freeing parents from the task. Moses puts the words on the parents’ hearts first. The class may assist, but it cannot carry what the text assigns to the home.
Other passages that speak to Deuteronomy 6:6-9
Several related studies help fill out this picture. Psalm 78 shows how one generation is charged to tell the next, which is the wider purpose behind any teaching ministry. Matthew’s account of the Great Commission roots all teaching in the authority of Christ and his ongoing presence, which steadies anyone who teaches. Paul’s letters to Timothy give practical instruction on sound doctrine, on overseers and servants in God’s house, and on guarding faith and godliness across generations. Read together, these passages show that the classroom and the home are not rivals but partners in one calling. To explore further, see What Does 1 Timothy 1:15 Mean? Context, Theology, and Application, 1 Timothy 1: Grace, Mercy, and Sound Doctrine, 1 Timothy 3: Overseers and Servants in God's House, and 1 Timothy 4: Guarding Faith and Godliness.
Frequently asked questions
Is Sunday school commanded in the Bible?
No. Sunday school as a weekly class is a historical development, not a biblical command. What Scripture commands is that God’s words be taught to children, that they be on the heart of the teacher, and that they be spoken in ordinary life. A class is one faithful way to obey that command, but the command is not tied to a particular program, hour, or room. Churches are free to organize teaching differently, as long as the substance and the setting of Deuteronomy 6 remain in view.
Whose job is it to teach children the faith?
Deuteronomy 6 gives the primary responsibility to parents and to the home, and the wider assembly shares in it. Parents are told to teach their children diligently, in the house and along the way. The church joins that work through gathered teaching and worship, as Acts 2:42 describes the early believers continuing in the apostles’ teaching together. The two are not in competition. A child is best served when both the home and the congregation take the task seriously and reinforce one another.
What should a Sunday school teacher aim for?
A teacher should aim at understanding and obedience, not attendance or entertainment. 2 Timothy 3:14-17 says the Scriptures are profitable for teaching, reproof, correction, and instruction in righteousness, which means the whole counsel of God belongs in the classroom, taught with patience and hope. Practical goals follow: help children know the passage, grasp what it means, and see how it applies. A teacher who does this, week after week, serves the home and the church at the same time.
