XLIX. To Penitents.
You have become a penitent; pray night and day; yet from your Mother the Church do not far depart, and the Highest will be able to be merciful to you. The confession of your fault shall not be in vain. Equally in your state of accusation learn to weep manifestly. Then, if you have a wound, seek herbs and a physician; and yet in your punishments you shall be able to mitigate your sufferings. For I will even confess that I alone of you am here, and that terror must be foregone. I have myself felt the destruction; and therefore I warn those who are wounded to walk more cautiously, to put your hair and your beard in the dust of the earth, and to be clothed in sackcloth, and to entreat from the highest King will aid you, that you perish not perchance from among the people.
