Another question of method concerns the utilization in catechetical instruction of valid elements in popular piety. I have in mind devotions practiced by the faithful in certain regions with moving fervor and purity of intention, even if the faith underlying them needs to be purified or rectified in many aspects. I have in mind certain easily understood prayers that many simple people are fond of repeating. I have in mind certain acts of piety practiced with a sincere desire to do penance or to please the Lord. Underlying most of these prayers and practices, besides elements that should be discarded, there are other elements which, if they were properly used, could serve very well to help people advance towards knowledge of the mystery of Christ and of His message: the love and mercy of God, the Incarnation of Christ, His redeeming cross and resurrection, the activity of the Spirit in each Christian and in the Church, the mystery of the hereafter, the evangelical virtues to be practiced, the presence of the Christian in the world, etc. And why should we appeal to non-Christian or even anti-Christian elements refusing to build on elements which, even if they need to be revised or improved, have something Christian at their root?
