Here is a significant book comprising Joseph Ratzinger's report on the debates and struggles that made up each of the four sessions of Vatican II (1962-65), along with theological commentary by a noted scholar and professor.

At the council Ratzinger worked on the Dogmatic Constitution on Divine Revelation (Dei verbum), the Dogmatic Constitution on the Church (Lumen gentium), and the Decree on the Missionary Activity of the Church (Ad gentes). Topics he treats in detail in the book include the debate on the liturgy schema, the early debate on divine revelation, the questions of Mariology and ecumenism, the decree on the bishops office in the Church, religious liberty, the Church and the Jews, and the schemas on the missions and on priestly ministry and life. He gives special attention to the Dogmatic Constitution on the Church and to the Pastoral Constitution on the Church in the Modern World.
