Gravissimum Educationis is
Vatican II's
Declaration on Christian Education. Passed by a vote of 2,290 to 35 of the assembled bishops, it was promulgated on
October 28,
1965 by
Pope Paul VI. The title means "importance of education" in
Latin and is drawn from the first line of the declaration, as is customary with
Roman Catholic documents.
