St. Tikhon of Zadonsk 1724-1783
God will not ask you Whether you taught your children French, German or Italian or the politics of society life – but you will not escape divine reprobation for not having instilled goodness into them. I speak plainly but I tell the truth: if your children are bad, your grandchildren will be worse…and the evil will thus increase…and the root of all this is our thoroughly bad education. (On The Duty of Christian Parents to Their Children and of Children to Their Parents)
