The interest that leads me to develop this article is to elaborate the first phases of the urgent and irreversible dialogue and confrontation between the human sciences and the Liturgy. Corresponding to the requests of the Second Vatican Council, where, finally, the Liturgy turned its back to the stigma of a legal discipline that dealt with ceremonials and initials, therefore without any theoretical foundation. This research is part of themes that I have been deepening since 2015, with publications in some theological journals in Brazil. In this text, I have sought to clarify from the beginning and have constantly kept in mind the proper object of a liturgical science: the rite, both as a human dimension of religious experience and as an ecclesial modality of Christian faith. Moreover for that we have authors who, like R. Guardini and L.M. Chauvet, followed this line at different times. The privileged references are to the ludic dimension of the liturgy (Guardini) and to the symbolic language of the sacraments (Chauvet). Symbol and game constitute two indispensable poles for a more correct cinematic understanding of liturgical practice understood as ritual mediation of faith.
