"You write—'I would like that my husband and I could escape the destructive disagreement in matters of upbringing that I seem to observe in almost all marriages.' Yes, this is truly a subtle thing! But it is not good to argue about this in front of the children, as you yourself noticed. Therefore, in cases of dispute, either turn away from it and leave, or pretend not to have heard it—but never argue about your differing views in front of the children. Counsel and discussion about this should be in private and as dispassionate as possible, so that it will be more real. Incidentally, if you succeed in implanting the fear of God into your children's hearts, then various human foibles cannot have such a corrupting effect on them."
