1917 Code of Canon Law in the context of "Promulgation (Catholic canon law)"

In the Catholic Church, an association of the Christian faithful or simply association of the faithful (Latin: consociationes christifidelium), sometimes called a public association of the faithful, is a group of baptized persons, clerics or laity or both together, who, according to the 1983 Code of Canon Law, jointly foster a more perfect life or promote public worship or Christian teaching, or who devote themselves to other works of the apostolate.

A 20th-century resurgence of interest in lay societies culminated in the Second Vatican Council, but lay ecclesial societies have long existed in forms such as sodalities (defined in the 1917 Code of Canon Law as associations of the faithful constituted as an organic body), confraternities (similarly defined as sodalities established for the promotion of public worship), medieval communes, and guilds.

Decretals (Latin: litterae decretales) are letters of a pope that formulate decisions in ecclesiastical law of the Catholic Church.

They are generally given in answer to consultations but are sometimes given due to the initiative of the pope himself. These furnish, with the canons of the councils, the chief source of the legislation of the church, and formed the greater part of the Corpus Iuris Canonici before they were formally replaced by the Codex Iuris Canonici of 1917. However, Cardinal Pietro Gasparri led the papal commission for the revision of canon law and later on published a guide to the fontes (sources) used in the 1917 code. Many canons in this code can easily be retraced in their relationship to and dependency on medieval decretals as well as Roman law.

The 1983 Code of Canon Law (abbreviated 1983 CIC from its Latin title Codex Iuris Canonici), also called the Johanno-Pauline Code, is the "fundamental body of ecclesiastical laws for the Latin Church". It is the second and current comprehensive codification of canonical legislation for the Latin Church of the Catholic Church. The 1983 Code of Canon Law was promulgated on 25 January 1983 by John Paul II and took legal effect on the First Sunday of Advent (27 November) 1983. It replaced the 1917 Code of Canon Law which had been promulgated by Benedict XV on 27 May 1917. According to canon 6, the 1983 code of canon law abrogates the 1917 code of canon law and any penal laws made under it that are not contained in the 1983 code.

The 1983 Code of Canon Law is composed of laws called canons.

The Corpus Juris Canonici (lit. 'Body of Canon Law') is a collection of significant sources of the Canon law of the Catholic Church that was applicable to the Latin Church. It was replaced by the 1917 Code of Canon Law which went into effect in 1918. The 1917 Code was later replaced by the 1983 Code of Canon Law, the codification of canon law currently in effect for the Latin Church.

The Corpus Juris Canonici was used in canonical courts of the Catholic Church such as those in each diocese and in the courts of appeal at the Roman Curia such as the Roman Rota.

Pope Pius X (Italian: Pio X; born Giuseppe Melchiorre Sarto; 2 June 1835 – 20 August 1914) was head of the Catholic Church from 4 August 1903 until his death in August 1914. Pius X is known for vigorously opposing modernist interpretations of Catholic doctrine, and for promoting liturgical reforms and Thomist scholastic theology. He initiated the preparation of the 1917 Code of Canon Law, the first comprehensive and systemic work of its kind, which was ultimately promulgated by his successor. He is venerated as a saint in the Catholic Church.

Pius X was devoted to the Blessed Virgin Mary under the title of Our Lady of Confidence; while his papal encyclical Ad diem illum took on a sense of renewal that was reflected in the motto of his pontificate. He advanced the Liturgical Movement by formulating the principle of participatio actuosa (active participation of the faithful) in his motu proprio, Tra le sollecitudini (1903). He encouraged the frequent reception of Holy Communion, and he lowered the age for First Communion, which would become a lasting innovation of his papacy.

Raymond of Penyafort OP (Catalan: Sant Ramon de Penyafort, IPA: [ˈsan rəˈmon də ˌpɛɲəˈfɔɾ]; c. 1175 – 6 January 1275) was a Catalan friar with the Dominicans who was a canon lawyer. He compiled the Decretals of Gregory IX, a collection of canonical laws that remained a major part of Church law until the 1917 Code of Canon Law abrogated it. He was canonized by Pope Clement VIII in 1601 and is the patron saint of canon lawyers.

He wrote one of the first manuals for user of the inquisitors, the Directorium inquisitoriale (1242).
