The Common Catechism
The Common Catechism: A Book of Christian Faith is an ecumenical Christian catechism that is the result of Catholic-Protestant dialogue and work. It was first published in 1973 and is the first joint catechism published by theologians of the Catholic Church, and the Lutheran Church and the Reformed Church, among other Protestant traditions, since the Reformation: The Common Catechism is ecumenical not only in drawing on the resources of scholars of many nations, but also on all the major Western Christian traditions.
