Harmony or Discordance between Sacramental and Liturgical Theology?

This paper aims to show a way of approximating between liturgical studies and sacramental theology, trying to undo a too formal separation between the two sciences. The paramount cause is to be found at the request of Sacrosanctum Concilium, starting from the link between the two to achieve a greater and more fruitful participation of those faithful to the sacraments. In the words of Card. Ratzinger, this request has not been fully met. The dichotomy and relationship between the notions of theoria and praxis in both sciences are presented as the need for a solid foundation or philosophical frame of reference with a metaphysical or realistic background, attending to the problems raised by the International Theological Commission in the document on “The Reciprocity between Faith and Sacraments in the Sacramental Economy” (1999). The pathway is open, some solutions are proposed, and an attempt is made to show the importance of this subject for the understanding of man himself and his Christian life.
