I believe A Little Catholic Catechism
- Vatican City Kirche in Not / Ostpriesterhelfe 2004
catechism should faithfully and systematically present the teaching of Sacred Scripture, the living Tradition in the Church and the authentic Magisterium, as well as the spiritual heritage of the Fathers, Doctors and saints of the Church, to allow for a better knowledge of the Christian mystery and for enlivening the faith of the People of God. It should take into account the doctrinal statements which down the centuries the Holy Spirit has intimated to his Church. It should also help to illumine with the light of faith the new situations and problems which has not yet emerged in the past. This catechism will thus contain both the new and the old (cf. Mt 13:52), because the faith is always the same yet the source of ever new light. (Apostolic Constitution "Fidei Depositum")
