I've read 13 of the 16 documents of Vatican II. The three remaining are Christus Dominus (on Bishops), Perfectae Caritatis (on Religious Life), and Gaudium et Spes (on the Church in the Modern World). I've loaded all 16 into the Magisterial Document Search Tool.
I'll be making use of them in the near future. What did Vatican II say about the sacraments? About the liturgy? Look for posts answering these and other questions in the coming weeks.
