Once in the chair of [[Saint Peter]], Gregory XIII dedicated himself to reform of the Catholic Church. He implemented the recommendations of the [[Council of Trent]]. He mandated that cardinals reside in their [[Episcopal see|see]]s without exception, and designated a committee to update the [[Index of Forbidden Books]]. Gregory XIII was also the patron of a new and greatly improved edition of the {{lang|la|Corpus juris canonici}}. In a time of considerable centralization of power, Gregory XIII abolished the Cardinals [[Papal consistory|Consistories]], replacing them with Colleges and appointing specific tasks for these colleges to work on. He was renowned for fierce independence; some confidants noted that he neither welcomed interventions nor sought advice. The power of the papacy increased under him, whereas the influence and power of the cardinals substantially decreased.{{Citation needed|date=August 2020}}

Gregory XIII also established the [[Discalced Carmelites]], an offshoot of the [[Carmelite Order]], as a distinct unit or "province" within the former by the decree "Pia consideratione" dated 22 June 1580,<ref>Otilio Rodriguez, OCD, Appendix I: The Third Order of the Teresian Carmel; Its Origin and History, page 129, in Michael D. Griffin, OCD, ''Commentary on the Rule of Life'' (superseded) (The Growth in Carmel Series; Hubertus, Wisconsin: Teresian Charism Press, 1981), pages 127-36; and Peter-Thomas Rohrbach, OCD''Journey to Carith: The Sources and Story of the Discalced Carmelites'', Chapter 6: The Struggle for Existence, page 200 (Washington: ICS Publications)</ref> ending a period of great difficulty between them and enabling the former to become a significant religious order in the Catholic Church.
