II.13-15
13. The Lord said: "whosoever shall offend one of these little ones that believe in me, it is better for him that a millstone were hanged about his neck, and he were cast into the sea" [Matt 18:6; Mark 9:42]. Therefore, I am afraid "lest I would be enveloped [from the flocks of your companions]" [cf. Song 1:7], that is, lest I would be separated from the only truth by the treachery of false priests and not naked and plainly apparent so that "your companions", that is the apostolic people, can see my pure and inviolate integrity and simplicity without any embellishment of deceit, that is not enveloped in any cloak of falsity. 14. The Lord had said that they would come to his Church "in sheep's clothing, but inwardly they are ravening wolfs" [Matt 7:15], and the holy Apostle had warned that after his departing the grievous wolfs would come, not sparing the flock [cf. Acts 20:29], that is heretics who devour the people of Christ by doctrine illicit because of sin. 15. Then after this words of menace uttered by the Lord, listen: "If thou not know, o thou fairest among women", he said, "go thy way forth by the footsteps of the flock" (Song of Songs 1:8). By these words He encouraged her to guard the faith and to provide a great care for the religious faith. Because the Church, a holy, simple and inviolate dove, greatly fears false, as I have said, doctors and corrupters of her virginity, who came in the clothing of the priests of God, that is "ravening wolfs in sheep's clothing", as the Lord had preached, and the Church asked for an account in the definite explanation of the evangelical truth "where he feeded, where he lied in the midday" [Song 1:6], that is, as I have said, in the combination of God and man, so that no one would separate God from man, or man from God, by some deceitful examples, then the Lord answered [to the Church]: "If thou not know, o thou fairest among women", that is, if you do not know that only you are a fair and uncorrupted virgin without stain, without wrinkle, and you shall be such as the Lord had shown and the Apostle defined: "go thy way forth", he said "by the footsteps of the flock".
