Theological disagreements on particular moral issues often reflect underlying but unnoticed differences on the more general question of how a theologian properly makes any moral judgment. This course draws on the writings of Bernard Lonergan to explore both (i) that more general question and (ii) current theological disagreements on two particular issues of sexual morality, namely, contraceptive acts and homosexual acts. Previous familiarity with Lonergan's work is helpful but not required. Readings include selections from Lonergan's writings and Vatican documents.
