Purpose of the paper: 1. Investigate the role of the laity prior to Vatican II. 2. Understand the role of the laity in documents since Vatican II: – Lumen Gentium – Evangelii nuntiandi (Pope Paul VI) – Familliaris Consortio (Pope John Paul II) 3. Contrast between the pre-Concilliar/ post-Concilliar. For an example of this theology before the Council you might refer to Mystici Corporis 82-84, where the unity of the faithful are conceived in a eucharistic theology that draws heavily upon sacrifice. Compare later with, for example, Ratzinger’s Called to Communion. 4. I need other sources to support to this paper (Catholic Thoughts). The sources that you will work Must Be academic works (Books and Articles From the Library University). Footnotes must be clear and specific. 5. Notice: you must be distinguish the catholic thoughts and Lutheran thoughts. They are different. I want you work on thoughts of Catholic doctrine.
