Editing Humanae vitae (section)

===Drafting of the encyclical===
In his role as [[Theologian of the Pontifical Household]], [[Mario Luigi Ciappi]] advised [[Pope Paul VI]] during the drafting of {{lang|la|Humanae vitae}}. Ciappi, a doctoral graduate of the {{lang|la|Pontificium Athenaeum Internationale Angelicum}}, the future [[Pontifical University of Saint Thomas Aquinas]], {{lang|la|Angelicum}}, served as professor of dogmatic theology there and was Dean of the {{lang|la|Angelicum}}'s Faculty of Theology from 1935 to 1955.

According to [[George Weigel]], Paul VI named Archbishop [[Karol Wojtyła]] (later Pope John Paul II) to the commission, but Polish government authorities would not permit him to travel to [[Rome]]. Wojtyła had earlier defended the church's position from a philosophical standpoint in his 1960 book ''[[Love and Responsibility]]''. Wojtyła's position was strongly considered and it was reflected in the final draft of the encyclical, although much of his language and arguments were not incorporated. Weigel attributes much of the poor reception of the encyclical to the omission of many of Wojtyła's arguments.<ref>{{cite book|last=Weigel|first=George|title=Witness to Hope|publisher=HarperCollins|orig-year=1999|year=2001|isbn=978-0-06-018793-4|quote=The encyclical was not drafted precisely as Wojtyla proposed.|url=https://archive.org/details/witnesstohopebio00weig}}</ref>

In 2017, anticipating the 50th anniversary of the encyclical, four theologians led by Mgr. Gilfredo Marengo, a professor of theological anthropology at the [[Pontifical John Paul II Institute for Studies on Marriage and Family]], launched a research project he called "a work of historical-critical investigation without any aim other than reconstructing as well as possible the whole process of composing the encyclical". Using the resources of the Vatican Secret Archives and the [[Congregation for the Doctrine of the Faith]], they hope to detail the writing process and the interaction between the commission, publicity surrounding the commission's work, and Paul's own authorship.<ref>{{cite news|last1=Wooden|first1=Cindy|title=Theologians studying development of Humanae Vitae given access to Vatican Secret Archives|url=http://catholicherald.co.uk/news/2017/07/27/theologians-studying-development-of-humanae-vitae-given-access-to-vatican-secret-archives/|access-date=27 July 2017|work=Vatholic Herals|date=27 July 2017}}</ref><ref>{{cite news|last1=San Martín|first1=Inés|title=No, Virginia, there's no 'secret commission' on Humanae Vitae|url=https://cruxnow.com/commentary/2017/07/27/no-virginia-theres-no-secret-commission-humanae-vitae/|access-date=27 July 2017|work=CRUX|date=27 July 2017|archive-date=27 July 2017|archive-url=https://web.archive.org/web/20170727080835/https://cruxnow.com/commentary/2017/07/27/no-virginia-theres-no-secret-commission-humanae-vitae/|url-status=dead}}</ref>
