I beseech you, sister Florentina, that women who do not hold one and the same profession with you may not come to your fellowship. For what they love, that they suggest: and they will pour into your ears those things which are bound up in their own desires. Alas for me, sister, evil communications corrupt good morals (1 Cor. XV). With the holy you shall be holy: far be it from you, sister, that with the perverse you should be perverted (Ps. XVII). What has the married woman in common with the virgin? She does not follow you, who loves a man; she flees your purpose; and even if she has feigned to love you, she lies in order to deceive. What does she have to do with you, with whom you do not draw the yoke of Christ on a common neck? Unlike in dress, unlike in affection.
This organ of Satan will sing to you that which may stir you by the allurements of the world, and may make fat the paths of the devil. Flee the songs of the Sirens, my sister: lest, while you delight to hear earthly delights with itching ears, you be turned aside from the straight way, and either be dashed upon a rock on the right hand, or be swallowed up on the left by the gaping maw of Charybdis. Flee the songs of the Sirens, and hedge your ears against the tongue of the evil counselor. Fortify your heart with the shield of faith, when you see one unlike your own purpose; and arm your brow with the trophy of the cross against her who is unlike your profession.
