Niedzielna Eucharystia, jej znaczenie w historii i we wspólnocie Kościoła

The article presents the sacrament of the Eucharist in the perspective of Sunday, because this sacrament is the source of the whole Christian life, and the Church lives thanks to the Eucharist (Ecclesia de Eucharistia vivit). It presents an overview of the major changes in the liturgy and the theology of the Holy Mass on Sunday, as well as the value of Sunday for the People of God. The liturgy, especially the Sunday liturgy, is not a theological treatise or a scientific lecture, but a celebration of the mystery of Christ, that is, the action of God himself together with the gathered People of God. It is an authentic confession of faith and a sign of belonging to the Church of God and union with him. The faithful, when they do not understand the spirit and meaning of the rites, withdraw, sometimes looking for other forms of religiosity. Therefore, there is a need to encourage, educate and prepare them for a fuller participation in the Sunday liturgy, which is, after all, of fundamental importance for the life of the Church and its individual members. It is the liturgy that effectively creates communion and educates to communion. The liturgy, especially the Sunday liturgy, lived in the full communion of the Church, reveals the entire mystery of Christ, from the Incarnation and Nativity to the Ascension and Pentecost, and the expectation of the blessed hope and coming of Christ. It is the realization of God’s plan of salvation and the continuation of the history of salvation to which all are called.
