“The fact that a man slips into accidental sins demonstrates the weakness of his nature; for to our profit God has permitted our nature to be susceptible to sinful occurrences. For He has not thought it good to make the soul superior to these occurrences before the second regeneration. It is profitable for the soul to be susceptible to accidental sins because this pricks the conscience. To persist in them is, however, audacious and shameful.”
As man I deliberately transgressed the divine commandment, when the devil, enticing me with the hope of divinity (cf. Gen. 3:5), dragged me down from my natural stability into the realm of sensual pleasure; and he was proud to have thus brought death into existence, for he delights in the corruption of human nature. Because of this, God became perfect man, taking on everything that belongs to human nature except sin (cf. Heb. 4:15); and indeed sin is not part of human nature, In this way, by enticing the insatiable serpent with the bait of the flesh. He provoked him to open his mouth and swallow it. This flesh proved poison to him, destroying him utterly by the power of the Divinity within it; but to human nature it proved a remedy restoring it to its original grace by that same power of the Divinity within it. For just as the devil poured out his venom of sin on the tree of knowledge and corrupted human nature once it had tasted it, so when he wished to devour the flesh of the Master he was himself destroyed by the power of the Divinity within it.
