Course introduces students to systematic theological reflection on the sacramental economy and the concept of sacramentality in general including the introduction and subsequent adoption of of the term sacramentum; on the Seven Sacraments in general; and on each of these seven in particilar.  This reflection presents the perspective of the Roman Catholic tradition, especially as represented by the teachings of St. Thomas Aquinas: namely, that (1) the Seven Sacraments are instituted by Christ, derive their power from him, and introduce us to his divine life; and that (2) they are celebrated by the Church so that this life may be professed and shared. Requirements: assigned readings, submission of student's commentary and questions in response to assigned readings for each session; a research paper of 2500-3000 words which includes a proposal and an annotated bibliography; and a final exam. Intended Audience: MDiv or MA Theology students; other graduate students admitted with permission.
