Saint Catherine of Siena: In wicked ministers, the sin against nature (the vice of homosexuality) reigns. (The Dialogue, 124)
I displease this last sin, because I am the Eternal Purity. It is to Me so abominable that by its cause I made disappear five cities. (cf. Genesis 19, 24). My Justice is not able to support it more.
That sin, nevertheless, does not only dislike to Me. It is even unbearable to the demons, who are had by patterns by those unfortunate ministers.
The demons do not tolerate that sin. They do not wish the virtue, but by his angelical origin, they challenge to see so stinking vice.
They throw the poisoned arrows of lust, but they turn round at the moment at which the sin is committed ".
