John Bonus of Milan, St.


Bishop; b. Camogli, Italy, end of sixth century; d. Jan. 2 (3?), 660. John (Giovanni) Camillus the Good was bishop of Milan from 649 until his death. The name Camillus derived from Camogli, where he was born of a noble family; the cognomen Bonus became attached to him in his own time because of his great prudence, magnanimity, and especially his easy friendship with and love of neighbor. He fought strenuously against Monothelitism and had a part in the lateran council of 649. His cult grew only after the discovery and translation of his relics by Bp. Aribert of Milan in the 11th century. His remains are at present in the cathedral of Milan, brought there by Charles borromeo in 1582.

Feast: Jan. 10.

Learn more about citation styles

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:

  • 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.
