This is especially the case with regard to the administration of the sacrament of Reconciliation, in which doctrinal affirmations confront concrete human situations and the spiritual paths of the individual faithful. It has become necessary, in fact, to recall firm points of reference which make it possible to deal pastorally both with new methods of contraception and the aggravation of the entire phenomenon."
