ChapterIII-VIII. Readings in Honor of Saints
166. The "hagiographical" readings or readings in honor of saints are either texts from a Father of the Church or another ecclesiastical writer, referring specifically or rightly applicable to the saint being commemorated, or the readings are texts from the saint's own writings, or are biographical.
167. Those who compose particular propers for saints must ensure historical accuracy  as well as genuine spiritual benefit for those who will read or hear the readings about the saints. Anything that merely excites amazement should be carefully avoided. Emphasis should be given to the individual spiritual characteristics of the saints, in a way suited to modern conditions; stress should also be laid on their contribution to the life and spirituality of the Church.
168. A short biographical note, simply giving historical facts and a brief sketch of the saint's life, is provided at the head of the reading. This is for information only and is not for reading aloud.
