Textbooks are aids offered to the Christian community that is engaged in catechesis. No text can take the place of a live communication of the Christian message; nevertheless, the texts do have great value in that they make if possible to present a fuller exposition of the witnesses of Christian tradition and of principles that foster catechetical activity. The putting together of these texts requires a co-operative effort by a number of catechetical experts, and also consultation with other experts.
