Dialog of Catherine of Siena

“The fruits of this death-giving tree, are as diverse as sins are diverse. See that some of these fruits are the food of beasts who live impurely, using their body and their mind like a swine who wallows in mud, for in the same way they wallow in the mire of sensuality. Oh, ugly soul, where have you left your dignity? You were made sister to the angels, and now you are become a brute beast. To such misery come sinners, notwithstanding that they are sustained by Me, who am Supreme Purity, notwithstanding that the very devils, whose friends and servants they have become, cannot endure the sight of such filthy actions. Neither does any sin, abominable as it may be, take away the light of the intellect from man, so much as does this one. This the philosophers knew, not by the light of grace, because they had it not, but because nature gave them the light to know that this sin obscured the intellect, and for that reason they preserved themselves in continence the better to study. Thus also they flung away their riches in order that the thought of them should not occupy their heart. Not so does the ignorant and false Christian, who has lost grace by sin.”
