“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.”
(St Tikhon of Zadonsk,  ‘Spiritual Treasure’)
