John of Montmirail, Bl.


Cistercian monk; b. 1165; d. Longpont Abbey, Sept. 29, 1217. An impetuous and loyal knight in the service of King philip ii augustus of france, he converted to a less worldly life and established a hostel near his castle, where he himself cared for the sick. In 1210 he left his wife and children to become a cistercian monk at the Abbey of Longpont in the diocese of Soissons. There he distinguished himself by his extraordinary devotion to the virtues of obedience and humility. His relics were translated to the abbey church in 1253, and he was honored as early as 1491 in the Cistercian martyrology. His cult was approved July 19, 1891.

Feast: Sept. 29 (Italian Cistercians and in the Dioceses of Soissons and Châlons-sur-Marne).

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
