From St. John Chrysostom’s Homily 21 on Ephesians 6:1-4
“Let everything take second place to our care for our children, our bringing them up in the discipline and instruction of the Lord. If from the beginning we teach them to love true wisdom, they will have greater wealth and glory than riches can provide. If a child learns a trade, or is highly educated for a lucrative profession all this is nothing compared to the art of detachment from riches; if you want to make your child rich, teach him this. He is truly rich who does not desire great possessions or surround himself with wealth, but who requires nothing.
This is how to discipline and teach your child; this is the greatest of riches. Do not worry about giving him an influential reputation for worldly wisdom, but ponder deeply how you can teach him to think lightly of this life’s passing glories; thus he will become truly renowned and glorious. Whether you are poor or rich, you can do this; these lessons are not learned from a skillful professor but from divine revelation. Do not ask how he can enjoy a long life here, but how he can enjoy an infinite and eternal life in the age to come. Give him the great things, not the little things. Do not strive to make him a clever orator, but teach him to love true wisdom. He will not suffer if he lacks clever words; but if he lacks wisdom, all the rhetoric in the world cannot help him. A pattern of life is what is needed, not empty speeches; character, not cleverness; deeds, not words. These things will secure the Kingdom and bestow Gods blessing. Do not sharpen his tongue but purify his soul.”
