CATECHISM OF THE CATHOLIC CHURCH
"The Catechism of the Catholic Church, which I approved 25 June (1991) and the publication of which I today order by virtue of my Apostolic Authority, is a statement of the Church's faith and of catholic doctrine, attested to or illumined by Sacred Scripture, the Apostolic Tradition and the Church's Magisterium. I declare it to be a sure norm for teaching the faith and thus a valid and legitimate instrument for ecclesial communion. May it serve the renewal to which the Holy Spirit ceaselessly calls the Church of God, the Body of Christ, on her pilgrimage to the undiminished light of the Kingdom!"
