The Catechism of the Catholic Church and local catechisms: the symphony of faith

136. The Catechism of the Catholic Church and local catechisms, each, with its own specific authority, naturally, form a unity. They are a concrete expression of the "unity of the same apostolic faith", (⁴⁷⁰) and, at the same time, of the rich diversity of formulations of the same faith. To those who contemplate this harmony, the Catechism of the Catholic Church and local catechisms together express a "symphony" of faith, a symphony inherent above all in the Catechism of the Catholic Church which has been drawn up with the collaboration of the entire Episcopate of the Catholic Church, a symphony harmonized with this and manifested in local catechisms. This symphony, this "chorus of voices of the universal Church", (⁴⁷¹) heard in the local catechisms and faithful to the Catechism of the Catholic Church, has a very important theological significance.

– It manifests the Catholicity of the Church: the cultural riches of the peoples is incorporated into the expression of the faith of the one Church.

– The Catechism of the Catholic Church and local catechisms make manifest to the ecclesial communion of which "the profession of the one faith" (⁴⁷²) is one of the visible links, "in which and formed out of which the one and unique visible Church of Christ exists". (⁴⁷³) The particular Churches, "parts of the one Church of Christ", form with the whole, the universal Church, "a peculiar relationship of mutual interiority" (⁴⁷⁴) The unity which thus exists between the Catechism of the Catholic Church and local catechisms makes visible this communion.

– The Catechism of the Catholic Church and local catechisms equally express, clearly, the reality of episcopal collegiality. The Bishops, each in his own diocese and together as a college, in communion with the Successor of Peter, have the greatest responsibility for catechesis in the Church. (⁴⁷⁵)

The Catechism of the Catholic Church and local catechisms, by their profound unity and rich diversity, are called to be a renewing leaven of catechesis in the Church. Contemplating them with her Catholic and universal gaze, the Church, that is, the entire community of the disciples of Christ, can say in truth: "This is our faith, this is the faith of the Church".
