This present research is a dialogue between two fundamental themes and at the same time challenging for the pastoral agenda of the XXI century: initiation into Christian life and parochial institution. Initiate faith, in the end times of sociological Christianity, and to attract community life, when growing religious disinstitutionalization, are not easy tasks. The Church has been committed to respond to these challenges. In the catechumenate, is found the great pastoral rediscovery of faith initiation. It treats a privileged way to transmit faith, ripen it and make it progress. The catechumenal pedagogy has fundamental characteristics for the maturity of the Christian being, such as the progressing of faith, the marriage catechesis- liturgy, strong mystagogic density and experiential of faith, among others. However, the catechumenate depends on renewed ecclesial structures, and here we come to the parochial level, whose institutional fatigue does not come today, as they are not today s attempts of renewals. Our research shows that fundamentally, it is seem that, the Christian Initiation catechumenal and the parochial renewal are not two distinct themes , therefore, should be thought of together, in the certainty that the future of one depends on the vitality of the other, and vice versa . There is a very close relationship between them, a happy dependency, which we call dialectical relationship. The catechumenal dynamical is essential not only for the Christian initiation, but questions, provokes, enlightens parochial conversion, and this , as it renews itself, is decisive for the consolidation and catechumenal practice. Therefore, it treats a relational process of mutual illumination. Among new model of parochial, and consolidating catechumenal practice, the future of one depends on the vitality of the other.
