The Code of Canon Law establishes the legal framework of the Latin Church, preserving specified concordats, privileges, customs, and liturgical laws while replacing conflicting earlier legislation. It sets norms for promulgation, interpretation, custom, decrees, privileges, dispensations, governance, offices, legal acts, and time. It defines the rights and duties of the faithful, clerical formation and obligations, associations, personal prelatures, papal and episcopal authority, diocesan and parish structures, and temporary governance. It also regulates institutes of consecrated life, secular institutes, societies of apostolic life, admission, formation, vows of chastity, poverty, and obedience, communal life, apostolic work, departures, and dismissal, emphasizing ecclesial communion, lawful authority, accountability, pastoral care, and fidelity to mission.

The Code governs the Church’s teaching and evangelizing mission, education, communications, publications, liturgy, sacraments, marriage, sacramentals, sacred places, and cemeteries. It establishes rules for holy days, Sunday worship, fasting, abstinence, and dispensations, then regulates ecclesiastical property, financial administration, taxation, donations, charitable bequests, and donors’ intentions. Its penal system addresses culpability, penalties, remedies, offenses, reform, justice, reparation, and prevention of scandal. Extensive judicial and administrative procedures cover tribunals, evidence, appeals, marriage nullity and separation, challenges to ordination, investigations, recourse, and the removal or transfer of pastors, with emphasis on fairness, canonical equity, pastoral care, and the salvation of souls.
