Persons with failed marriages constitute a marginalized sector of the ecclesial community, requiring a targeted outreach in keeping the Church’s call to evangelize all sectors of society. In this vein, CANL 512 Introduction to Marriage in Canon Law is a pastorally oriented course intended to introduce the foundational elements of marriage in canon law. It thus responds to Pope Francis’s call for the establishment of diocesan and parish ministries to assist those with doubts concerning the validity of their marriage. In this eight-week course, students will explore the natural law basis and ecclesiastical law structure of marriage as established for the Latin Catholic Church. Having explored these foundations, the course then explores fatal defects which may lead to invalidly tendered marital consent. This course will be eminently practical, including case studies and mock pastoral exercises. It seeks to provide a working familiarity with key concepts for persons working in parish ministry, adult faith formation and sacramental initiation, marriage ministers, and those curious about the workings of diocesan marriage tribunals.
