[1.15.2] "O brother, why do you eat the flesh of the serpent when there is plenty of fruit available to satisfy your hunger? Our father Adam drank of the juice of a plant he did not know and which the serpent had prepared with cunning and mastery in its boundless malice to destroy him and his descendants. Because of that he sinned before the Lord of all justice, and all of you through him. And I myself was burdened with the weight of the guilt before God and had to do penance like you who all drank of the juice of perdition, and like you I had to leave Paradise and take your burden upon myself bodily and all your blessings spiritually and thus had a twofold burden because of all.
[1.15.3] "And you eat the flesh of the live serpent together with its blood. Why did you do that, Cain?"
