St John Chrysostom on having children study the Bible, in a homily on Ephesians 6.1–4:
Don’t say, ‘Bible-reading is for monks; am I turning my child into a monk?’ No! It isn’t necessary for him to be a monk. Make him into a Christian! Why are you afraid of something so good? It is necessary for everyone to know Scriptural teachings, and this is especially true for children. Even at their age they are exposed to all sorts of folly and bad examples from popular entertainments. Our children need remedies for all these things! We are so concerned with our children’s schooling; if only we were equally zealous in bringing them up in the discipline and instruction of the Lord! And then we wonder why we reap such bitter fruit when we have raised our children to be insolent, licentious, impious, and vulgar. May this never happen; instead, let us heed the blessed Paul’s admonition to bring them up in the discipline and instruction of the Lord. Let us give them a pattern to imitate; from their earliest years let us teach them to study the Bible.
Having just come back from the 2017 Thematic Bible Conference in Princeton, I heartily approve. Even children can learn through inductive Bible studies to study the word of God for themselves, and even older high-schoolers should learn to make ready and lead a systematically inductive Bible study. It can be done, if only we will get it done by faith.
