The Paschal Mystery of Christ made present in the sacramental liturgy is a model of spiritual growth of Christians on the way of purification, illumination, and unificati-on. The transition (Passover) of Christ from death to life is a model of a Christian way. Christians live in connection with the paschal mystery every day when they strive to do what is more perfect and when they express the newness of life in the performance of good deeds. The participation in the transition of Christ through death to a new life consists in abandoning the way of life of a sinful man and striving for deeds of a man renewed in the mystery of Christ’s death and His glorious resurrection. Faith received at baptism enables a man to participate in the paschal mystery of Christ and offers a participation in the resurrection of the Son of God. The union with Christ and remai-ning in Him is the participation in the sacrifice of the Savior according to the paschal theology. The Passover is an event that brightens with its splendor not only the life of the individual Christian, but also the whole history of mankind. The final fulfillment in Christ is the purpose of the whole universe.

This paper focuses on three issues. First, it is about the context and environment of pre-Nicene theology. It is emphasized that pre-Nicene theology did not neglect ca-techetical and liturgical reflection (ad intra) while at the same time successfully ente-red into a critical and creative dialogue with both the Semitic and Greco-Roman world where first Christians lived (ad extra). For contemporary theology its means that it cannot reject historical reasoning, placed in space and time. The second part stresses that, in spite of different situations and all historical and cultural contexts, theology before Nicea was above all an understanding of Sacred Scripture to which the key is the Risen Christ as the source and definitive fulfilment of the inspired writings. Finally, the third part of the paper focuses on the existential and spiritual experience from which pre-Nicene theology originated. For this theology the Gospel of Christ is not just the rule of faith but also the rule of life. This leads to a conclusion that a contem-porary theologian is a to take up an existential-personalistic reflection on Revelation using the historical-hermeneutic method .
