Research a saint or Catholic leader from a moment of great change in the Church: Post-Resurrection (33 A.D. - 350 A.D.), Post-Constantine (313 A.D. - 1400 A.D.), Post-Reformation (1519 A.D. - 1700 A.D.), Post-Enlightenment (1620 A.D. - 1815 A.D.), or The Contemporary Church (1959 A.D. - Today). What was their motivation? How did they move the Church closer to her mission? How were they perceived by others at the time of their work? How are they seen today? What can we learn from their work in the Church and in the world?
