Ponderings of an Old Theologian is a book in which the author reflects on his life as a youngster and a seminarian in the pre-Vatican II Catholic Church, as a priest and missionary in the Philippines, and as a resigned priest and lay teacher at a Catholic school. The Second Vatican Council (1962-5) and Pope John XXIII had a life-shaping effect on him throughout his journey. Early on, he decided to help implement the renewals of Vatican II, and did so as a missionary and a teacher. In simple language, his narrative and reflections cover the development of Catholic thinking through several generations and look at the papacy of Pope Francis as the hope of a real Vatican II Church. The work invites the readers to find how they can make Vatican II relevant in their lives (part memoir, part reflection on Catholic theology).
