Former dicasteries Praedicate evangelium (Preach the gospel[1]) is an apostolic constitution reforming the Roman Curia and was published and promulgated on 19 March 2022 by Pope Francis; the document took effect on 5 June 2022.

According to the official communiqué, the Pope had stated that the reform coming with the constitution was "already underway, also in some administrative and economic aspects".

He says: "Now it is a question of giving homogeneity to all the reforms which have been made, by means of the new apostolic constitution which has for at least provisional title: 'Predicate Evangelii [sic]'".

[11] Cardinal Parolin stated in July 2021: "The text [of the constitution], which aims to give a coherent framework to all the reforms already undertaken, is currently being examined by canonists to adapt the terminology to the juridical character of the document".

[2] Praedicate evangelium confirms the changes previously made by Pope Francis to the structure of the Congregation for the Doctrine of the Faith in February 2022.

[17] The document states: "This new apostolic constitution proposes to better harmonize the present exercise of the Curia's service with the path of evangelization that the church, especially in this season, is living".

[20][1] The constitution says the role of Catholic laity in taking part in the governing of the Roman Curia is "essential" due to their familiarity with family life and "social reality".

The apostolic constitution states without giving any more precision that officials must have "an adequate number of years of experience in pastoral activities" before being appointed.

The doctrinal section must also "examin[e] writings and opinions that appear contrary or harmful to the right faith and morals", seek "dialogue with their authors and presen[t] suitable remedies to be made, in accordance with its own norms" and "endeavo[r] to ensure that there is an adequate refutation of the dangerous errors and doctrines which are spread among the Christian people".

[2] The apostolic constitution gives the Dicastery for Divine Worship and the Discipline of the Sacraments responsibility for "promoting the sacred liturgy according to the renewal undertaken by the Second Vatican Council"[22] and "the regulation and discipline of the sacred liturgy with regard to the use — granted according to established norms — of the liturgical books prior to the reform of the Second Vatican Council".

Furthermore, "[t]he dicastery confirms the translations of liturgical books into current languages and gives recognitio [formal recognition] to their appropriate adaptations to local cultures, legitimately approved by the bishops' conferences".

The first section has broad responsibilities; those include "attending to the handling of affairs concerning the daily service of the Roman Pontiff," coordinating the work of dicasteries "without prejudice to their autonomy," drafting papal documents such as apostolic letters, and giving "indications to the Dicastery for Communication regarding official communications concerning both the acts of the Roman Pontiff and the activity of the Holy See".

[26] In April 2022, Pope Francis stated that the book-length interview of cardinal Oscar Rodriguez Maradiaga on the constitution, titled Praedicate Evangelium: A new curia for a new time, "adequately unravels the meaning and itinerary of this meticulous and decisive work of revision and proposals".

[27] In a June 2022 interview, Pope Francis stated Praedicate evangelium was the culmination of "eight-and-a-half years of work and inquiries".

He adds that the document implements the requests made by cardinals before the 2013 conclave, and places "a missionary-style experience" at the heart of the Catholic Church's work.
