The thesis deals with the questions, how the Christians in the Liturgy of Saint John Chrysostom remind themselves the history of salvation and how they make the history of salvation present (i. e. anamnesis of the history of salvation) trough the symbols followed by the word. In the first part the author deals with the Christians symbolic acts in the liturgy as the symbolic acts express their relation to God. In the next part he pays attention to the process of the celebration of the liturgy of Saint John Chrisostom. These themes that describe symbolic acts of celebration are followed by the chapter that deals with the spiritual aspects of the liturgy. For a better orientation in the next text he closes the introductory part with the theological conception of the selected authors of the liturgical commentaries. In the main part of the thesis the author focuses on the history of the liturgy and on the liturgical commentaries of the selected authors of the Orthodox Christianity, who influenced the development of the Byzantine liturgy. Further, he focuses on the analysis of the present text of the liturgy of Saint John Chrysostom, where he searches for the ways the anamnesis of the history of salvation is reached. In the final part of the work he presents the results of the analysis and concludes that the Jesus life is really reminded and made present in the particular parts of the Byzantine liturgy.

La présente thèse a pour principal objectif l’analyse empirique et théologique de la participation active (PA) des pratiquants dominicaux au sein de deux communautés montréalaises catholiques romaines. Les débats portant sur l’objet de l’étude sont encore ouverts eu égard aux récentes réappropriations religieuses des contemporains et aux nouveaux modes culturels. Cette thèse se penchera succinctement sur le sens historique de ce principe, pour ensuite privilégier l’évolution contemporaine des discussions. Ce sont, tout particulièrement, les catégories de participation théologale, externe, interne, communautaire et d’expérience liturgique qui constitueront le cadre d’observation qualitative de cette étude. La notion de PA est en pleine évolution depuis la réforme voulue par Vatican II. En s’appuyant sur des postures théologiques récentes, cette thèse vise à savoir comment les différents paramètres de la PA sont perçus et vécus chez certains pratiquants. Du point de vue pastoral, cette thèse prend appui sur ce courant théologique pour interroger les manières de faire participer les pratiquants pour leur faire vivre authentiquement le mystère eucharistique en s’inspirant notamment des perspectives patristiques. Elle procède aussi à l’étude de l’expérience liturgique des pratiquants suivant les traces de Join-Lambert et de Jean Séguy. Ces théologiens ont traité des problématiques liées au champ émotionnel de la liturgie, Séguy le subordonnant au rituel régulé et rationnel dans le Catholicisme romain. Tout en faisant état des dissidences théologiques concernant cette notion, sujet à controverse, cette thèse conclut que les réformes conciliaires ont eu des impacts positifs sur la pratique liturgique. Elle indique que la participation liturgique paraît moins envisagée sous l’angle d’un rapport implicatif, que d’un rapport électif à la liturgie dominicale. Exprimant des attentes à la fois rituelles rationnelles et rituelles émotionnelles, les pratiquants recherchent davantage l’expérience d’une rencontre personnelle avec Dieu, alors que certains valorisent l’assemblée elle-même. Ensuite, la thèse révèle les enjeux liés au défi ministériel. Surgit la question de la centralité de la figure du prêtre, à l’heure de la synodalité en Église. / The main focus of this thesis is the empirical and theological analysis of the active participation (AP) of Sunday churchgoers in two Roman Catholic Montreal communities. Debates on the object of the study are still open in view of the new religious reappropriations of contemporaries and new cultural modes. This thesis will briefly examine the historical meaning the notion of AP, to then focus on the contemporary evolution of the debate. It is, in particular, the categories of external, internal, community participation and liturgical experience that will constitute the qualitative observation framework of this study. The concept of PA is in full evolution since the reform desired by Vatican II. Based on recent reflections, this thesis aims to know how the different parameters of AP are perceived and experienced by some practitioners. From a pastoral point of view, this thesis is based on this theological current to question the ways of involving practitioners in order to make them live authentically the Eucharistic mystery by drawing inspiration in particular from patristic perspectives. It also proceeds to the study of the liturgical experience of practitioners following in the footsteps of Join-Lambert and Jean Séguy, theologians who have dealt with issues related to the emotional field of the liturgy, Séguy subordinating it to regulated and rational ritual in Catholicism. While noting the theological disagreements concerning this controversial notion, this thesis concludes that the conciliar reforms have had positive impacts on liturgical practice. It indicates that liturgical participation seems less envisaged from the angle of an implicative relationship, than of a selective relationship to the Sunday liturgy. Expressing both rational ritual and emotional ritual expectations, practitioners seek more the experience of a personal encounter with God, while just some value the assembly itself. Then, the thesis reveals the issues related to the ministerial challenge. The question of the centrality of the figure of the priest arises at a time when synodality in the Church is being considered.

The presented work deals with the conception of the Eucharist in the Gospel of John. The first chapter is dedicated to terms of the Eucharist, the Last Supper and the Lord{\crq}s Supper and also to the existing division of possible approaches to the sacramentality in the Gospel of John. In the subsequent chapters it deals in detail with five places of the Gospel of John, that are mostly mentioned in connection with the Eucharist. It is the wedding at Cana (2,1-11), the eucharistic section (6,51-58), washing of the feet of disciples (13,1-20), the Vine and the Branches (15,1-17), opening of the side of Jesus (19,34). The work tries to solve the topic (question) in the context as wide as possible including the question of the johannine sources of inspiration. In this way it can be seen the mutual correspondence of these varios places and the deep theological conception of the hole Gospel. The replacement of the institution of the Eucharist in the thirteenth chapter with the washing of the feet and it{\crq}s displacement to {\clqq}the bread of life discourse`` in the sixth chapter is due to the proper evangelist{\crq}s intention. There was an impending danger, that the Eucharist became a magical medicine without any relation to the incarnation and the sacrifitial death of Jesus. These facts have theirs own consequences for the life of the christian community. So the subject of the sacraments has been subordinated to the christological accent.
