9.1 [603] So then, by taking up our shield a longside the doctrines of the truth with the utmost endurance, so it seems to me, we have held our own against the nonsensical words of those who know only how to disparage our doctrines.1 But because our opponent bears down upon the ineffable glory with all his sails unfurled and dares, as it were, to lead forth his profane ideas in unbearable assaults, expending his most effective resources on the task of stripping the nature of God the Father of his progeny and stripping the true Son, who came from his nature, of his hypostasis2 (for he does away with his existence and engages in such extremely perilous undertakings), come now, “putting on the breastplate of justice,” while also lifting up “the shield of faith” and whetting against him “the sword of the Spirit, which is the word of God,”3 let us show that he is a liar and in his extreme arrogance all but kicks against the goads4 and leaps down into the deep pit of destruction.5 [604]
