According to the United States Conference of Catholic Bishops, “The Catechism consists of 2,865 paragraphs, each of which is numbered. There is an internal cross-referencing system among the paragraphs which makes it simple to find all the passages in the Catechism which treat a particular subject. In addition, the Catechism provides several indices for ease in locating particular passages. Indices are organized according to themes, Scriptural citations, symbols of the faith, documents of ecumenical councils, documents of other councils and synods, pontifical documents, ecclesiastical documents, canon law, liturgical texts, and ecclesiastical authors.”
It is at the level of doctrine, and all people are obliged to accept.
