The Vatican II bishops issued four constitutions, nine decrees, and three declarations.
The four constitutions are considered the foundation works of the Council. They are joined in the sidebar by three declarations now, the ones on relations with non-Christian religions, Christian education, and religious freedom. Seven more decrees to go.
Maybe this is a good time to field suggestions on future Church documents to examine. That seems to be an ingrained thing on this web site. And there’s seemingly no end to Church teaching in various official formats ranging from papal letters to conciliar constitutions.
