As the Apostle says, ‘Do not be little ones in understanding, be little ones in malice.’What is being a little one in malice? A baby has no malice. If he is not treated with honor he is not angry; if he is honored, he is not subject to vainglory. If what he has is taken away he is not troubled. To be a little one in malice means having no desire for revenge and laying no claim to glory.
