2. Vain, therefore, and truly miserable, are those who do not choose to see what is so manifest and clear, but shun the light of truth, blinding themselves like the tragic Œdipus. And as those who are not practised in wrestling, when they contend with others, laying hold with a determined grasp of some part of [their opponent's] body, really fall by means of that which they grasp, yet when they fall, imagine that they are gaining the victory, because they have obstinately kept their hold upon that part which they seized at the outset, and besides falling, become subjects of ridicule; so is it with respect to that [favourite] expression of the heretics: "Flesh and blood cannot inherit the kingdom of God;" while taking two expressions of Paul's, without having perceived the apostle's meaning, or examined critically the force of the terms, but keeping fast hold of the mere expressions by themselves, they die in consequence of their influence (περὶ αὐτὰς), overturning as far as in them lies the entire dispensation of God.
