This work is an investigation of the ongoing methodical reconstruction of Catholic moral theology. As such it is based on and honors the work of Norbert Rigali, S.J., one of the most important contributors to this reconstruction. The decisive break from the traditional manual approach to moral theology represented by Vatican II reoriented moral theology away from universal natural law morality based on the commandments to a morality based on specifically Christian sources. This reorientation, however, was not an either/or but a both/and proposition. Father Norbert Rigali, S.J. has been an inspiration and a challenge to moral theologians working toward reconstruction. This essays in this collection address four questions in the renewal movement: an investigation of normative methods, a clarification of sources, an investigation of the tension between natural law morality and Christian ethics and/or morality, and a combination of methodical insights of philosophy and traditional Christian sources in their investigation of biomedical ethical issues.
